Half-Life: Evacuation Protocol

Half-Life: Evacuation Protocol is a concept for a fan-made expansion/mod for the video game Half-Life by Red-Verse-Writer, inspired by the official expansions Opposing Force and Blue Shift as well as the fan-made expansions Dark Matter and Echoes. Focused on showing the Black Mesa Incident from the perspective of another character, the player is placed in the role of Nicholas Carter, a minor worker at the Black Mesa topside facilities who during the HECU attack upon the facility is forced to travel beneath to the labs' lower and more infested levels, leading to him having to fight for his life against the Xen lifeforms.

Melee

 * Machete: The main melee weapon of the game, replacing the Crowbar. It functions almost identically to the Crowbar, but does slightly more damage per hit. It reuses the Machete model from Counter-Strike Condition Zero: Deleted Scenes.
 * Fire Axe: The slowest and strongest of the four melee weapon, replacing the Pipe Wrench. While very slow to use, it deals immense damage on hit, enough to kill a Alien Slave in a single hit.
 * Wrench: The fastest but weakest melee weapon in the game, replacing the Combat Knife. It does half the damage of the Machete, but swings twice as fast and has a alternate fire mode where the Wrench is thrown at a enemy to deal damage. Once thrown, the Wrench must be picked up again. It reuses the unused old Wrench model from Team Fortress Classic.

Smaller Firearms

 * Glock 17: The first gun acquired in the game. It has two firing modes - a standard semi-automatic mode and a slower but quieter, more accurate and stronger sniper mode by using a silencer. It reuses the standard Glock 17 and unused silencer models from Half-Life.
 * .357 Magnum: A significantly stronger but slower handgun variant with near-perfect accuracy. While it is strong enough to take down nearly all enemies in one or two shots, it is limited due to its scarce ammunition and slow firing and reloading speed. It reuses the scoped .357 Magnum model from Half-Life.
 * TMP: A rapid-fire fully automatic weapon, replacing the MP5. While it lacks the grenade launcher add-on of the MP5, it compensates by being more accurate and having a higher rate of fire. It reuses the Schmidt Machine Pistol model from Counter-Strike.
 * Shotgun: A powerful mid-range weapon, replacing the SPAS-12. Unlike the SPAS-12, it cannot fire two barrels at once and does less damage per shot, with its main compensation being significant accuracy. It reuses the Shotgun model from Deathmatch Classic.
