Team Fortress Classic: Source

"'Anyone remember Half-Life: Source? Valve's port of Half-Life to the Source engine? It wasn't anything special - just a direct copy and paste with some improved graphics, but a LOT of bugs and glitches despite running on a technically superior engine. It was disappointing to fans who actually wanted a proper remake, which we didn't get until the spectacular Black Mesa over a decade later. A direct contrast to Counter-Strike: Source - the game that did kind of the same thing for the original Counter-Strike, but actually gave some improvements to the gameplay, weapons and physics. I also remember reading that some people were trying to make a similar thing for Team Fortress Classic, but it's apparently been cancelled due to behind-the-scenes drama and other things. Then I came up with another idea - doing something similar, but instead of a direct port, a complete overhaul to the original game, with new ideas, new gameplay mechanics, and new styles of tackling a problem. And so Team Fortress Classic: Source was reborn!'"Team Fortress Classic: Source is a Source mod concept by Red-Verse-Writer, a remake of Team Fortress Classic based on a cancelled mod of a similar name.

Gameplay
Team Fortress Classic: Source revolves around two teams, Red and Blue (although sometimes there is additional Green and Yellow teams), who can choose between nine (although sometimes ten) different classes. Each character class has a different set of weapons, abilities, strengths and weaknesses that count another class's in a rock-paper-scissors style of gameplay - in order to accomplish objectives efficiently, a balance of these classes is required due to how these strengths and weaknesses interact with each other in a team-based environment. Each class has four weapons - a melee weapon, a tertiary sidearm weapon, a primary weapon and a secondary weapon. The game also supports several different gameplay modes, including new game modes such as Domination, which features teams attempting to take control of all the specialised control points on a map while protecting their own control points from the enemy; Special Delivery, where one is attempting to push a cart along a track to the enemy's base while the other team attempts to stop them; and Murderball, a soccer-style game where each team is attempting to grab a single ball and deliver it to the enemy team's goal. The older game modes also return from the original game - Capture the Flag, where both teams attempt to steal the enemy's flag whilst keeping their own safe; Control Points, where each team must bring a flag to each control point to capture it; and Attack/Defend, where each team takes turns to either capture control points or defend against the enemy team, are unchanged, whilst Escort now features both teams being given a randomly selected Civillian, who they must safely escort to a given point while also trying to assassinate the enemy team's Civillian before they can reach the same point.

Compared to the original game, Team Fortress Classic: Source provides a complete overhaul to the gameplay and its mechanics. Each class is now capable of constructing their own unique building, with the Engineer class still being vital for repairing and upgrading these buildings. Engineers can regenerate their armour, see friendly buildings and ammo sources through walls, and create new sources of any type of ammo. They can also construct multiple new types of buildings, with their list now including security cameras for monitoring rooms, motion sensors for detecting enemy Spies, field generators to protect a area from enemies, amplifiers to improve a teammate's abilities for a brief period of time, repair nodes to automatically heal nearby buildings when the Engineer is not available, and Multi-Guns, which are initially inert turrets but can be transformed into a unique turret by having a different teammate run through it (for example, a Sniper can upgrade it into a Flak Cannon, which fires slowly but does immense damage on shot), as well as the returning Sentry Gun, Dispenser and Teleporter. Medics can build up Supercharges by healing allies, and can expend this charge to provide themselves and any nearby teammates with invulnerability for a short period of time. They can heal allies and infect enemies from a distance by throwing gas balls, and can build Buff Stations to provide players with portable charges that can be activated to provide a temporary buff. Scouts can perform parkour-style moves by building up momentum in order to perform feats such as vaulting over surfaces or enemies, sliding along the ground, and running along walls. They can also double-jump and build Speed Pads which can be reconfigured to either provide a teammate with a speed buff by running over it or function like a catapult and propel them a great distance. Pyros can fly around on jetpacks, throw cans of gasoline to use as explosives, and build Snark Nests to spawn the Snarks from Half-Life, which can serve as a distraction and harass the enemy team. Spies can eavesdrop on the enemy team's private conversation, sabotage a enemy building to make it function like a friendly building for a period of time, and use a motion-based cloak to become invisible for periods of time. They can also see enemies through walls via thermal vision and can build Mounted Sentry Guns which can be hidden on walls or ceilings to surprise attack enemies. Soldiers can perform Bullrushes to knock down and damage enemies whilst travelling great distances, and gather energy from dealing and taking damage to charge a Battlecry that temporarily increases the speed and damage of the user and all nearby teammates who hear the Battlecry. They can also deploy parachutes in mid-air to float and glide, and can build Bunkers for teammates to hide within. Snipers can build Anti-Rocket Shields to protect themselves and teammates from enemy explosives, and can partially cloak themselves when moving slowly and not attacking. They can also see enemies they hit but do not kill through walls, use a limited but self-regenerating supply of flares to light up dark areas or set enemies on fire, and call in airstrikes to devastate outdoor areas. Demomen can build Stationary Mortars that can be controlled using laser pointers, see placed explosives through walls, and remotely detonate their thrown grenades. They can also perform a shockwave stomp when landing from a great height and are immune to falling damage. Heavies can perform stomps that do no damage but momentarily stop a enemy from moving, use a Portable Medkit to heal their injuries or the injuries of a teammate, and gain a temporary damage buff on a killstreak. They also now take less damage from attacks and can build Security Pods to protect teammates, which can piloted and flown around in. Finally, if available, Civilians naturally provide all nearby bodyguards with a defensive buff and can grant a teammate a temporary buff to their health, speed, damage and damage resistance.

Due to the usage of the Source engine and improved computer software, the game features improved physics and graphics compared to the original Team Fortress Classic. Players can now sprint, which uses up a limited but self-regenerating Stamina meter, and the level of a player's armour can be upgraded from light to medium to heavy by an Engineer reinforcing the armour. Grenades can bounce off of walls when thrown, Animations mesh together (for example, rather than suddenly slumping to the ground instantly when killed, a player killed in mid-air will go limp in the air before slumping to the ground when they land) and play more fluidly. Each class has their own unique hand models in first-person, and the third-person models match the first-person models. Character models are much more high-poly and flexible, each class has their own unique voices and lines, and their mouths move when the player talks using a microphone. Maps are also much larger, and many feature interactable objects, such as ziplines and mounted machine guns. Health, armour and weapon damage is also increased, and ammunition now appears in specialized boxes, with backpacks filled with ammo only be spawned by either a player dying and dropping their ammunition or when a player is manually throwing spare or unneeded ammunition to a teammate. Servers can also now support a maximum of 128 players instead of just 32, and maps are much larger than ever before, with new paths, alternate routes, and secret areas.

 * Bullets: 600
 * Shells: 120
 * Rockets: 50
 * Energy: 200

The Scout is the fastest class in the game, and the most significantly changed from in the original game. As opposed to being exclusively focused on flag running like in Team Fortress Classic, he is more similar to his Team Fortress 2 counterpart, being a more combat-oriented character with a focus upon performing high speed, close range hit-and-run attacks. He is now capable of performing parkour feats when moving quickly, building up speed when moving to be able to run along walls, slide along the ground, and vault over enemies and obstacles. He can also double jump and wall jump even when not moving fast, further increasing his options, and can also use a radar scan to detect nearby enemies or friendlies. While his health and armour are both increased, he is still the most vulnerable of the main nine classes, unable to sustain much damage and needing to evade combat when possible. He also has very limited options outside of close range, requiring him to actively take risks and maintain momentum when in combat.
 * Role: Offense, objective capturing
 * Building: Speed Pad

Sniper

 * Health: 100/200 (Overheal)
 * Armour: 125/250 (Reinforced)
 * Standard Armour Type: Light Kevlar (absorbs 30% of all incoming damage and 50% of Bullet damage)
 * Speed: 100% (300 hu/s)/150% (450 hu/s, sprinting)
 * Weapons: Bat, Single-Barrel Shotgun, Sniper Rifle, Assault Pistol
 * Grenades: Hand Grenade, Freezing Grenade, Gravity Grenade
 * Special Abilities: Headshots, Scope Zoom, Headshot Immunity, Camouflage, Radio Tag, Flares, Airstrike Locating and Calling
 * Maximum Amount of Ammo Carried:
 * Bullets: 100
 * Shells: 75
 * Rockets: 40
 * Energy: 100

The Sniper is the master of long-range combat, a crack-shot with a focus upon destroying enemies from long-range. Able to blend into environments by staying still before taking a shot, he can instantly eliminate a enemy with a highly powerful headshot, being able trace enemies he hits but does not kill through walls. He can also provide support roles to his team by being able to use a limited but self-regenerating supply of flares to light up areas and alert them to incoming enemy attacks by observing their routes from afar, but his most powerful technique is to set spots for and then call in devastating airstrikes to utterly obliterate a outdoor area. While he has a large advantage over all enemies, his options at short-range are limited, requiring him to evade close-range encounters. He is also only slightly more durable than the Scout, further limiting his survival and capabilities in a firefight and requiring him to directly avoid confrontation unless absolutely necessary.
 * Role: Defence, elimination
 * Building: Anti-Rocket Shield

Soldier

 * Health: 300/600 (Overheal)
 * Armour: 500/1000 (Reinforced)
 * Standard Armour Type: Heavy Blast (absorbs 75% of all incoming damage and all Rocket or Grenade damage)
 * Speed: 80% (240 hu/s)/133% (400 hu/s, sprinting)
 * Weapons: Crowbar, Double-Barrel Shotgun, Rocket Launcher, Revolver
 * Grenades: Hand Grenades, Freezing Grenades, Nail Grenades
 * Special Abilities: Rocket Jumping, Automatic Reload, Quickswitch, Battlecry, Parachute Glide and Float, Bullrush, Last Resort
 * Maximum Amount of Ammo Carried:
 * Bullets: 40
 * Shells: 100
 * Rockets: 50
 * Energy: 100

The Soldier is the most flexible and one of the most powerful classes in the game. Tough and well-armed, he is able to assume many offensive roles, using his powerful weapons to take down attackers and punch holes in the enemy defence. He can automatically reload his weapons when not in use and immediately switch between his primary and secondary weapons, but his most notable ability is his spectacular rocket jump, launching a rocket at his feet to propel himself through the air at the cost of health. He can then deploy a parachute in mid-air to slow his fall, and perform bullrushes on the ground to travel across a small area quickly while knocking down enemies. As he takes damage, he can use his automatic Last Resort power to run faster and do more damage the closer he gets to death, and by dealing damage, he can charge up a Battlecry to temporarily enhance the performance of himself and nearby allies. While he lacks many exploitable weaknesses, he is not a master of one particular method of attack, and he has both slow ground speed and less effective methods of long-range combat, requiring him to understand map routes and be ready to get up close and personal with enemies to be effective.
 * Role: Offense, general offense
 * Building: Bunker

Demoman

 * Health: 200/400 (Overheal)
 * Armour: 300/600 (Reinforced)
 * Standard Armour Type: Heavy Blast (absorbs 75% of all incoming damage and all Rocket or Grenade damage)
 * Speed: 90% (270 hu/s)/133% (400hu/s, sprinting)
 * Weapons: Machete, Single-Barrel Shotgun, Grenade Launcher, C4
 * Grenades: Hand Grenades, MIRV Grenades, Claymore
 * Special Abilities: Pipebomb Jumping, Explosive Sight, Remote Grenade Detonation, Fall Damage Immunity, Shockwave Landing, Secret Path Sight, Laser Pointer
 * Maximum Amount of Ammo Carried:
 * Bullets: 20
 * Shells: 40
 * Rockets: 40
 * Energy:

The Demoman is the explosive master of the game and the class with the most direct firepower. Using many powerful explosive weapons that can be used for area denial, timed explosions, or even opening or closing alternative paths on the map, the Demoman is capable of seeing his placed explosives through any obstruction and can remotely detonate his thrown grenades. Tough and well-armed, he is also capable of performing long-distance Pipebomb jumps at the cost of health and armour, and is immune to taking damage from falling during this - in fact, he even creates a shockwave upon landing that pushes enemies back. His main weaknesses stem from his relatively slow speed, lack of accuracy with his weapons, danger of self-inflicted splash damage while using them, and the fact that his weapons take practise to master, requiring a efficient Demoman to train and understand physics to be able to effectively clear rooms and deal with enemy fortifications.
 * Role: Offense, room clearing
 * Building: Stationary Mortar

Medic

 * Health: 125/250 (Overheal)
 * Armour: 200/400 (Reinforced)
 * Standard Armour Type: Medium Shock (absorbs 50% of all incoming damage and all electrical or shock damage)
 * Speed: 120% (360 hu/s)/173% (520 hu/s, sprinting)
 * Weapons: Spade, Double-Barrel Shotgun, Medigun, Assault Rifle
 * Grenades: Hand Grenades, Concussion Grenades, Biological Grenades
 * Special Abilities: Health Regeneration, Infection Immunity, Infection, Supercharge, Overhealing, Medkit Enhancement, Dispenser Enhancement
 * Maximum Amount of Ammo Carried:
 * Bullets: 150
 * Shells: 80
 * Rockets: 20
 * Energy: 100

The Medic is the main healing force of the team and essentially the Scout's bigger, stronger brother. Possessing high speed and some powerful weapons, he is a proficient offensive support, able to both regenerate his own health and infect enemies with a deadly infection that spreads between enemies and can only be cured by a enemy Medic, surviving for long enough, or simply dying. This is, however, a secondary role to his main function as a team's primary healing force, being able to heal his allies, overheal them for extra health, enhance a healing source for a limited buff, and build up a Supercharge by healing allies before deploying it to give himself and nearby teammates temporary invulnerability. While these abilities can allow him to be a effective fighter, he lacks long-range capabilities, and while his health regeneration and armour can help him survive a few hits, he is not very durable and can be quickly brought down by sustained fire, requiring him to pick his battles and understand his function as a supporting player, healing allies while taking down lower-class enemies and causing panic on the enemy team with his infections.
 * Role: Offense, general support
 * Building: Buff Station

Heavy

 * Health: 500/1000 (Overheal)
 * Armour: 750/1500 (Reinforced)
 * Standard Armour Type: Heavy Metal (absorbs 75% of all incoming damage and all Shell or Cell damage)
 * Speed: 66% (200 hu/s)/128% (385 hu/s, sprinting)
 * Weapons: Hook, Double-Barrel Shotgun, Assault Cannon, Freeze Sprayer
 * Grenades: Hand Grenade, MIRV Grenade, Energy Field Grenades
 * Special Abilities: Slowdown Stomp, Damage Resistance, Killstreak Buff, Knockback Immunity, Portable Medkit, Enemy Tracking
 * Maximum Amount of Ammo Carried:
 * Bullets: 400
 * Shells: 200
 * Rockets: 100
 * Energy: 300

The Heavy is the strongest and most durable class, and the leader of any charge. Boasting the most health and armour of any class, he is able to sustain many attacks and take hits for his teammates, and even takes less damage per hit than anyone else. He is also a immensely powerful attacker, being able to shred through hordes of enemies in seconds, stop their movements with a shockwave stomp, resist knockback, track enemies he sees, and gain a temporary buff whenever he kills three enemies in one life. Aside from his immense attacking power, he can also be a lifesaver by using a Portable Medkit to restore a ally's health, or his own if needed. However, he is also the slowest class in the game, a easy target for Snipers, Pyros and Spies, and requires frequent support from his allies to stay in the fight and take out enemy attackers.
 * Role: Defence, defensive support
 * Building: Security Pod

Pyro

 * Health: 150/300 (Overheal)
 * Armour: 250/500 (Reinforced)
 * Standard Armour Type: Medium Asbestos (absorbs 50% of all incoming damage and all Fire or Smoke damage)
 * Speed: 100% (300 hu/s)/150% (450 hu/s, sprinting)
 * Weapons: Axe, Single-Barrel Shotgun, Incendiary Cannon, Flamethrower
 * Grenades: Hand Grenades, Smoke Grenades, Napalm Grenades
 * Special Abilities: Afterburn Immunity, Jetpack, Building Supplying, Airblasts, Gas Can Throw, Multi-Degree Burns, Upgrade on Kill, Fiery Combo, Emergency Rope
 * Maximum Amount of Ammo Carried:
 * Bullets: 75
 * Shells: 75
 * Rockets: 40
 * Energy: 500

The Pyro is the shield that keeps enemies away from the base and weaker teammates by cutting them down like a overclocked lawnmower. Focusing upon causing chaos and using divide-and-conquer techniques, she is able to use various flame-based attacks to burn enemies to death. Immune to fire herself, she can use streams of flame to ignite enemies, throw cans of gas to be ignited for massive explosions, do increased melee damage, and can push back enemies and their grenades. She can also assist her teammates by extinguishing them when on fire, resupplying buildings, or surveying enemies while flying around her jetpack, which has a limited but self-regenerating supply of fuel. While she is very powerful at close range, her options for long-range combat are quite limited, and while she has decent health and armour that can allow her to absorb several hits, her chances of survival are not as high as the heavier classes, requiring her to focus upon protecting a location from enemies and utilizing distraction techniques to allow her teammates to slip past the enemy defences untouched.
 * Role: Defence, frontline protection
 * Building: Snark Nest

Spy

 * Health: 125/250 (Overheal)
 * Armour: 200/400 (Reinforced)
 * Standard Armour Type: Light Asbestos (absorbs 30% of all incoming damage and 50% of Fire or Smoke damage)
 * Speed: 107% (320 hu/s)/170% (510 hu/s, sprinting)
 * Weapons: Knife, Double-Barrel Shotgun, Silenced Submachine Gun, Tranquilizer Gun
 * Grenades: Hand Grenades, EMP Grenades, Gas Grenades
 * Special Abilities: Disguise, Cloak, Backstab, Spy Disguise Removal, Fake Corpse, Building Sabotage, ID Theft, Silent Footsteps, Private Chat Eavesdropping
 * Maximum Amount of Ammo Carried:
 * Bullets: 300
 * Shells: 80
 * Rockets: 20
 * Energy: 50

The Spy is the assassin and saboteur of the game, waging a psychological war against the enemy using stealth and subterfuge whilst taking down enemies and buildings. Able to immediately eliminate a enemy from behind with a melee attack, he can also eavesdrop on their private chat and sabotage their buildings to make them work for him for a period of time. To aid him with these tasks, he can disguise himself as any enemy on their team, steal the identity of an enemy he kills, turn invisible with a motion-based cloak, move silently, and drop fake corpses when needed. While he has some average health and armour, as well as some sidearms to fight back if needed, he is quite vulnerable and lacks much offensive capabilities, requiring him to think and plan ahead before moving in and assist his allies in attacks by taking down the enemy defence from behind rather than directly attacking.
 * Role: Offense, sabotaging
 * Building: Mounted Sentry

Engineer

 * Health: 100/200 (Overheal)
 * Armour: 100/200 (Reinforced)
 * Standard Armour Type: Medium Shock (absorbs 50% of all incoming damage and all electrical or shock damage)
 * Speed: 100% (300 hu/s)/150% (450 hu/s, sprinting)
 * Weapons: Wrench, Submachine Gun, Railgun, Triple-Barrel Shotgun
 * Grenades: Hand Grenades, EMP Grenade, Laser Tripmines
 * Special Abilities: Armour Regeneration, Armour Repair, Armour Upgrading, Multiple Buildings, Building Repair, Building Upgrading, Ammo Creation, Ammo Sight
 * Maximum Amount of Ammo Carried:
 * Bullets: 300
 * Shells: 200
 * Rockets: 50
 * Energy: 1000

The Engineer is the main defensive building-orientated class of the game, fixing and upgrading their buildings whilst working as a guardian and logistician. The thinking man's class, the Engineer is able to construct a variety of buildings rather than just one, and can repair and upgrade both his buildings and his teammate's buildings to enhance their health and abilities. He can also repair and upgrade their armour, create new temporary sources of ammunition, see ammo sources through walls, and regenerate his own armour. While he is able to fight back with some decent weaponry, his low health and armour, barely more than the Scout's, prevent him from being a true offensive powerhouse and reinforce his purpose as a defensive operative and repairman, aiding teammates by protecting their buildings and objectives while they work to capture the enemy's base.
 * Role: Defence, general defence
 * Building: Multiple

Civillian

 * Health: 100/200 (Overheal)
 * Armour: 75/125 (Reinforced)
 * Standard Armour Type: Light Metal (absorbs 30% of all incoming damage and 50% of Shell or Cell damage)
 * Speed: 77% (230 hu/s)/120% (360 hu/s, sprinting)
 * Weapons: Umbrella, Submachine Gun, Lever-Action Rifle, Dual Pistols
 * Grenades: Flash Grenades, Smoke Grenades, Teleport Grenades
 * Special Abilities: Round Ending, Escape, Backstab Immunity, Sentry Gun Immunity, Morale Buff, Fake Ammo Creation, Remarkable Dying Skills
 * Maximum Amount of Ammo Carried:
 * Bullets: 50
 * Shells: 40
 * Rockets: 10
 * Energy: 50

Available only during Escort maps, the Civillian is a man with a price on his head and a target on his back. Barely able to fight by himself, he requires the assistance of his bodyguards to perform objectives and complete the map. Each team has one Civillian, who is randomly selected out of the available team members, and the teams must kill the enemy Civillian while keeping their own Civillian alive and helping him to the objective. While his only purpose is to be escorted to the ends of the map, he has a few abilities as well - he is immune to backstabs and building-based damage, provides a automatic buff to his nearby bodyguards that enhances their performance, and can create fake ammo traps that instead take away a enemy's ammunition. He also ends the round when he either dies or completes a objective.

Slot 2

 * Single-Barrel Shotgun: A relatively low-power but high-speed and effective shotgun used as a sidearm by the Sniper, Demoman and Pyro. While it does low damage per pellet and fires less pellets per shot than the Double-Barrel Shotgun, it has a tight spread and fires rapidly, and even more so does not suffer damage fall-off, making it ideal for taking pot-shots at enemies from long ranges, fighting an enemy when the user's primary weapon is ineffective or unusable, finishing off wounded enemies, or as a last-ditch weapon when other weapons are unloaded or will not be able to deal with a enemy in the current situation. It has a clip size of 8 rounds and uses Shells as ammo.
 * Double-Barrel Shotgun: A two-barrelled and very powerful shotgun used as a sidearm by the Soldier, Medic, Heavy and Spy. While it has limited damage fall-off over long ranges and a slower rate of fire compared to the Single-Barrel Shotgun, as well as consuming two Shells per shot, it more than compensates by firing much more pellets per shot and doing much more damage per shot, being able to be used to cut down a weak enemy or finish off a stronger enemy wounded by the user's primary weapon. It has a clip size of 16 rounds (technically 32, but two rounds are always consumed per shot, so the user only really has 16 shots) and uses Shells as ammo.
 * Submachine Gun: A medium power Uzi-like submachine gun used as a sidearm by the Scout, Engineer and Civillian. The replacement of the classic Nailgun (which still appears in the form of a frequent map decoration), it is a automatic weapon that fires a constant stream of bullets with high accuracy. These shots do not lose damage over range, but are relatively weak by themselves. Due to the constant stream of damage it does, it is ideal for fighting slower enemies or enemy buildings. Each class has a significant difference to their Submachine Gun - the Scout has extra ammunition in the clip and reloads slightly faster, the Engineer does more damage with it and fires even faster (as well as holding the gun on its side, although this is purely cosmetic), and the Civillian has a slower rate of ammunition consumption (only using one bullet per two shots). It has a clip size of 50 rounds (100 for the Scout) and uses Bullets as ammo.

Scout

 * Immense Speed: The Scout is, understandably, much faster than any other class.
 * Improved Stamina: The Scout possesses roughly 25% more stamina than any other class, and his stamina drops at a 20% slower rate when sprinting.
 * Improved Sprinting: The Scout has a much more significant speed boost when sprinting compared to other classes. While sprinting, the Scout moves at a extra 100% speed, as opposed to the other classes, who typically gain around a 50% speed boost when sprinting.
 * Increased Stamina Regeneration: The Scout's stamina, in addition to being higher and depleting slower, also regenerates at around 0.5x a faster rate than the other classes.
 * Double Jump: The Scout can jump or duck-jump twice when in mid-air. This can be used to travel distances faster, reach higher places and avoid enemy fire, although the double jump has a predictable trajectory and a careless double jump can put him in danger.
 * Parkour: When moving at at least 173% speed, the Scout is capable of performing parkour moves. He can grab onto and jump over ledges, leap further and higher, run along walls for a brief period, jump off walls, slide along the ground, vault over enemies and obstacles, and swing along corners to avoid losing speed. By using the Secondary Ability button (L by default), he is able capable of performing a dash followed by a mid-air dropkick, which does low damage to enemies but pushes them back significantly and stuns a enemy who is flung into a wall while also doing more damage. However, the Dropkick comes at a heavy stamina cost and causes the Scout to lose all his momentum.
 * C4 Disabling: The Scout can automatically disable a planted C4 by running over it.
 * Spy Disguise Removal: The Scout can automatically disable a Spy's disguise by touching them. This does not work on cloaked Spies. The Spy also has this ability.
 * Objective Location: While none of the Scout's weapons have alternate firing modes, he can instead use the alt-fire button (MOUSE2 by default) to locate all teams' objectives on a map. When used, the locations of these objectives will be announced to the user in the text chat, although allies and enemies will not be able to see this.
 * Radar Scan: By using the Special button (MOUSE3 by default), the Scout can turn on or off his radar, which allows him to detect allies and enemies up to 1500 HU/s away, as well as buildings, incoming grenades or projectiles, and cloaked or disguised friendly or enemy Spies. Using the Radar costs 10 Energy per second, requiring the user to turn it off when it is not needed to avoid expending spare Energy.
 * Leg Injury Immunity: The Scout is immune to the leg injury debuff caused by caltrops and melee attacks or Sniper Rifle shots below the belt.
 * Speed Pad: The Scout can construct a Speed Pad and set it between Boost or Catapult mode. Building a Speed Pad costs 100 Energy and 50 Shells.

Soldier

 * Rocket Jumping: The Soldier is capable of rocket jumping by jumping and firing a rocket at his feet or near him. This comes at a cost of health and armour (although the user only takes 25% of the regular damage caused by a rocket), but can be used to fly around the map, avoid enemies, or reach areas inaccessible without a Speed Pad in Catapult mode.
 * Automatic Reload: The Soldier's Double-Barrel Shotgun, Rocket Launcher and Revolver automatically reload themselves when he is not using them, meaning he can quickly pull them out when needed without fear of lacking a clip.
 * Quickswitch: When using Alt-Fire with the Revolver, the Soldier can immediately switch to the Double-Barrel Shotgun and vice-versa without the need to take a moment to switch weapons. However, he cannot quick switch to the Rocket Launcher, which takes roughly 1.8 seconds to switch to.
 * Battlecry: By doing damage to enemies, the Soldier gradually charges up a Battlecry meter visible on the HUD. When it is fully charged (by doing approximately 1000 damage to enemies), the Soldier can use the Special button to activate the Battlecry, letting out a thundering scream and enhancing his own performance, as well as any ally in a 400 HU radius. While under the effects of the Battlecry, which lasts for around 12 seconds, the user and all allies receive a 65% resistance to all damage done by buildings or grenades, a 40% resistance to all damage done by enemy weapons, a 50% increase in all damage done with their weapons, and a 25% speed bost.
 * Parachute Glide and Float: When his feet are off the ground by at least 100 HU, the Soldier can deploy a parachute by pressing the jump button (SPACE by default) again. This slows his fall, and prevents him from taking fall damage from landing. The Soldier's Rocket Launcher fires and reloads 25% faster while gliding after a rocket jump. A friendly Pyro can also ignite a pilot light attached to the parachute with any flame weapon, enabling the Soldier to constantly float on the same level of altitude for 10 seconds.
 * Bullrush: By using the Secondary Special button (L by default), the Soldier can perform a bullrush, charging forwards at around 200% speed for about 2 seconds. This can be used to travel across a small area quicker, but can mainly be used to knock down enemies, damaging and stunning them, or breaking down a door reinforced by a Engineer.
 * Rocket Launcher Scope: By using Alt-Fire with the Rocket Launcher, the Soldier can look down the scope attached to its side to take more precise shots or lock onto a target before unleashing a barrage. Unlike with the Sniper Rifle, this scope will sway by itself when in use - the Soldier can hold down the Sprint button (SHIFT by default) to steady it, but this costs Stamina.
 * Barrage: When the Rocket Launcher is scoped, it can be used to set a laser point for a location or enemy to barrage. It can then be fired to deploy its entire clip of five rockets in rapid succession, which home in on the target and do maximum damage on hit. This point can be kept whether or not the Rocket Launcher is still scoped, but it is possible for a enemy to avoid a barrage by running constantly and close to walls to try and use them to absorbs the explosions.
 * Last Resort: As the Soldier's health drops, his speed, melee damage, and damage resistance all increase proportionate to his health, meaning that at less than 25 health, he can run slightly slower than the Scout and kill any enemy lighter than a unarmoured but full-health Medic in one melee hit. Due to the danger this places him in, though, this is only recommended as an absolute last resort, as the name suggests.
 * Bunker: The Soldier can construct a Bunker and man its turret. Building a Bunker costs 75 Energy, 50 Shells and 75 Bullets.

Pyro

 * Afterburn Immunity: The Pyro is completely immune to afterburn inflicted by the Flamethrower, Incendiary Cannon, Napalm Grenades, or the Sniper's Flares, and also takes 40% less direct damage from these sources of fire.
 * Jetpack: The Pyro is capable of flying around on a jetpack by holding down the Special button whilst at least 25 HU off the ground, performing a initial lift-off that pushes enemies away before initiating flight. While flying, the player has roughly 300% increased air control and is continuously moving upwards, although this can be changed to instead be moving downwards or in any direction, still moving diagonally. The Pyro can then land without taking fall damage by pressing the Special button again to disable the Jetpack. While in use, the Jetpack burns up around 7.5% of its fuel supply every second, so the ability cannot be used constantly. The fuel resupplies itself at a rate of 2.5% per second.
 * Building Supplying: While using the Axe, the Pyro can resupply her own ammo into a friendly building. This is useful to help take the pressure off of friendly Engineers and can be a lifesaver.
 * Airblast: By using Alt-Fire while using the Flamethrower or Incendiary Cannon, the Pyro can use up 30 energy or 5 Rockets to fire a blast of compressed air in a forward field around herself. This can be used for multiple purposes, such as pushing a enemy back several feet or extinguishing a burning teammate (doing the latter will restore 20 health for the Pyro as a reward), but its main function is to deflect physical projectiles. A deflected projectile or grenade will function like a friendly projectile and damage any member of the enemy team, and is useful for repelling enemy fire, protecting the user and their teammates or buildings from grenades, or forcing enemies to back off. All physical projectiles and grenades can be deflected except for the darts fired from the Spy's Tranquilizer Gun and the energy beams of the Scout's EMP Pistol and the Engineer's Railgun.
 * Gas Can Throw: After doing around 1000 damage to charge up a Gas meter, the Pyro can use the Secondary Special button to throw a can of gas, which sprays gasoline over all a surface or enemy. After this, any contact with flames causes the gas to explode, doing massive damage to enemies and buildings. Since the Gas meter does not regenerate itself, it is thus necessary for the Pyro to use weaponry to fight against enemies before performing this attack.
 * Multi-Degree Burns: The Pyro does more damage with her fire weapons the more she forces the fire onto them. Igniting enemies with different weapons in a short period of time can be used to stack-up afterburn damage - a Level 1 afterburn, from simply touching a flame source for around a second, will do 6 damage per second for 5 seconds; a Level 2 afterburn, from being exposed to flame repeatedly or being shot with the Incendiary Cannon after being ignited by the Flamethrower or vice versa, will do 8 damage per second over 10 seconds; and a Level 3 afterburn, caused by similar techniques, will do 10 damage per second over 15 seconds.
 * Upgrade on Kill: Every time she gets a kill, the Pyro's abilities are upgraded. On getting a kill, her maximum health is increased from 150 to 165 and her maximum armour is increased from 250 to 300. On getting two kills, her maximum speed is increased from 100% to 110%. On getting three kills, her maximum health in increased again to 180 and the amount of Energy and Rockets she can carry is increased from 300 and 40 to 400 and 50. Finally, on getting four kills, her maximum stamina is increased by 25% and her maximum amount of Grenades is increased from 4 to 5. These upgrades last until she is killed, causing these rewards to reset. After four kills, no further upgrades are gained, but every kill restores the Pyro's armour by 25 points.
 * Fiery Combo: When a enemy is on fire, the Pyro can use the Axe or Single-Barrel Shotgun to do additional damage to them.
 * Emergency Rope: By pressing Alt-Fire using the Axe or Single-Barrel Shotgun, the Pyro can shoot a rope that can be used to attached to surfaces or enemies, similar to a grappling hook. This rope can be deployed to be used for the user, allies or enemies to climb along. Ropes last for 20 seconds before disappearing, and take 30 seconds to recharge.
 * Snark Nest: The Pyro can build a Snark Nest and cause their Snarks to do twice the damage to burning enemies. Building a Snark Nest costs 100 Energy, 40 Shells and 25 Rockets.

Changes to Gameplay and Classes
Rather than a direct port of the original Team Fortress Classic to the Source engine, Team Fortress Classic: Source features massive changes to the base gameplay, including character abilities and functions, physics, maps and playstyles. These changes are, as well as the majority being mentioned above, all listed here:
 * The general graphics and aesthetics of the game are slightly more unrealistic and "cartoony" than the original, mainly due to the developer's desire to combine the graphic styles of Team Fortress Classic and Team Fortress 2.
 * The GUI menu interface is changed, being simplifier and more easily accessible for players new to Team Fortress, as well as easier to use to give out voice commands. Key presses are, like in Team Fortress 2, now used to give out voice commands tied to a specific button.
 * Map-specific voice commands are more varied and can be used more frequently.
 * Maps are much larger, and almost all feature new alternate pathways. There is also a much greater emphasis upon interacting with the environment, with new hiding places, mounted stationary equipment such as machine guns and rocket launchers that can be manned and controlled by players, and ziplines that players can use to quickly travel across locations. There is also always at least one secret area that functions as a neutral zone, where players cannot damage each other, and features health and ammo restoratives.
 * All weapons have had their damage vastly increased.
 * Each class have had their health and armour increased to compensate the increased weapon damage:
 * Civillian has 100 health and 50 armour rather than 50 health and no armour.
 * Scout has 100 health and 75 armour rather than 75 health and 50 armour.
 * Engineer has 100 health and armour rather than 80 health and 50 armour.
 * Sniper has 100 health and 125 armour rather than 90 health and 50 armour.
 * Medic and Spy have 125 health and 200 armour rather than 90 health and 100 armour.
 * Pyro has 150 health and 250 armour rather than 100 health and 150 armour.
 * Demoman has 200 health and 300 armour rather than 90 health and 120 armour.
 * Soldier has 300 health and 500 armour rather than 100 health and 200 armour.
 * Heavy has 500 health and 750 armour rather than 100 health and 300 armour.
 * The level of a player's armour can be upgraded from light (30% protection) to medium (60% protection) to heavy (80% protection) by an Engineer reinforcing the armour, regardless of who the class is.
 * Each class has their own unique voices and lines of dialogue. The character's mouth also moves when they speak or when a player is using a microphone.
 * Microphone-using players can be muted if a player does not wish to hear them.
 * Due to the usage of the Source engine, physics and animations are improved. Animations mesh together (for example, rather than suddenly slumping to the ground instantly when killed, a player killed in mid-air will go limp in the air before slumping to the ground when they land) and play more fluidly. Each class has their own unique hand models in first-person, and the third-person models match the first-person models. Weapon physics are also tweaked, with grenades and pipebombs bouncing off walls more accurately, and players being able to sprint, allowing them to move faster for a short period of time before needing to wait for their stamina to regenerate. The HUD also displays animated images related to status and class, and the general graphics are improved.
 * Ammunition now appears in specialized boxes, like in the original Team Fortress mod. Backpacks filled with ammo are only spawned by either a player dying and dropping their ammunition or when a player is manually throwing spare or unneeded ammunition to a teammate. Backpacks will also never contain health pickups - these are exclusively found in the form of their own medical kit items.
 * Servers can support a maximum of 128 players (64 to 32 per team) instead of just 32 (16 to 8 per team).
 * Infection has been significantly nerfed and made more manageable, mainly due to how overpowered it was in the original Team Fortress Classic and to compensate for the fact that it is now possibly to heal and infect from a distance. Infection will automatically go away by itself if the victim survives for more than 20 seconds, and collecting a health kit while infected will reduce this time by 5 seconds in addition to the regular health boost. After surviving a infection, a player will become immune to further infection for 10 seconds.
 * The Demoman, Heavy and Civilian's speed has been reduced while the Scout, Medic and Spy's speed has been increased.
 * The Scout and Medic's functions are significantly changed. The Scout, as opposed to exclusively a flag-runner with limited offensive options, is instead more combat-oriented, and is focused upon performing high-speed hit-and-run attacks on enemies. The Medic, conversely, has had his combat abilities reduced while his healing abilities have been maximised, focusing upon his role as the team's healer.
 * The Crowbar is split up into different melee weapons for each class - a hammer for Scout, a cricket bat for Sniper, a crowbar for Soldier, a machete for Demoman, a spade for Medic, a hook for Heavy and a axe for Pyro. Melee combat is also much more useful than in the original Team Fortress Classic, with all melee weapons being much stronger and faster, as well as having a slightly longer range.
 * The Knife does a little more damage than in the original game, but otherwise functions the same.
 * The Wrench now does more damage than a regular melee weapon.
