Gunblazers: Shoot on Sight is a 3D light gun rail shooter developed and published by ACS. Released in 1997 for Arcades (ACS TGX Modeller System) and the PlayStation as an exclusive title.

Gameplay
The main objective of Gunblazers is to shoot as many on-screen enemies as the player can using a gun controller wired into the cabinet. The game uses light-based gun controllers, which uses a built-in optical sensor into the gun, to receive its input from the light emitted by on-screen targets.

From time to time, various enemies appear on-screen which attack the player in various ways, which the players then must shoot in order to move on to the next screen or else they damage. Most enemies are distinguished by their face-covering clothing and accessories such as sunglasses or ski masks, though boss characters usually have their faces bare.

When an enemy is about to fire, a flashing thin red and white ring, known as the "attack ring", appears around their hands that quickly shrinks in size, thus the player must shoot the enemy before the ring disappears unless they get shot. By default, standard enemies will take three seconds after appearing on-screen before firing at the player. The game uses a dynamic difficulty system that makes it so that the more enemies the player shoots, the less time they are given to shoot the next enemy before they attack back.

There are also “elite” enemies that give way less leeway and fire more quickly upon appearing on-screen. Enemies using melee weapons do not cast an attack ring around them, but are usually easier to spot because of their motions and position, being close to the screen. Enemies using throwing weapons and/or explosive artillery have visible ammunition that the players must shoot to avert damage. Same goes for most of the bosses in the game.

Sometimes, in the middle of the ongoing shootout, civilians can be seen appearing and leaving the premises, distinguished from the enemies by their bare faces. Shooting at civilians would lead to a score penalty and the player losing a life. Thus, the players must avoid shooting these civilians in order to get a bonus at the end of the level.

Players start off using handguns, each holding a capacity of six bullets. When all six bullets are spent, the words “Reload” will flash on-screen, and the player will be unable to shoot enemies. To reload their gun, players simply have to shoot off-screen to reload.

Gunblazers' main unique gameplay feature is the "Magnum Shot". By holding down the trigger for an extended period of time, a small meter will appear on the player's side, which quickly fills up as the player holds down the trigger. Upon releasing the trigger while the meter is full, the player will fire out a powerful shot that deals double the damage of a regular bullet. Firing a Magnum Shot costs 1 bullet.

Each player starts off with three lives by default, as denoted by a set of three medikits located on the corner of the screen. Upon taking damage from either being shot by an enemy or shooting a civilian by accident, the player loses a life. The player can replenish their lives by either shooting boxes scattered around the area to reveal medikits, or getting end-of-level bonuses.

The PlayStation home port of the game is compatible with both Namco’s GunCon and Konami’s Justifier/Hyper Blaster light gun peripherals.

Weapons
Along the way, players can pick up special weapons that increase their firepower and firing rate in various ways. These special weapons can be used for three reloads or until the player is shot, after which, the player reverts to the standard handgun. The Magnum Shot cannot be performed when any of these special weapons are equipped.

The player can pick up these special weapons by either shooting boxes scattered around the area to reveal the hidden special weapons, or killing “Elite” enemies, who would then drop these special weapons.

 * Several references to other ACS games can be seen all over the game. For example, a poster for Legendary Blades can be seen in the Liberty Mall stage.


 * The gun controllers in the arcade version feature a blowback feature that emulates a real-life handgun’s recoil, similar to the ones used in Namco’s Time Crisis series. This feature wasn’t retained in the console versions.


 * The PlayStation version features a second campaign called “Another Mission”, which features a new set of stages and a brand new storyline. The story for the Another Mission campaign isn’t canon.
