Terminator 2: Judgment Day or T2 is a light gun shooter based on the film of the same name, produced by Midway Manufacturing Company as an arcade video game in 1991. Developed in tandem with the movie, several actors from the film reprise their roles for the game and are featured as part of the game's photorealistic digitized graphics. The game's plot largely follows that of the film, casting up to two players as the T-800 "terminator" cyborg from the film, sent back in time to protect John Connor from assassination by the T-1000 terminator. A success in arcades, home conversions of the game were released by Acclaim Entertainment for various platforms under the title of T2: The Arcade Game to avoid confusion with the numerous tie-in games also based on the movie.

Light-gun shooter, also called light-gun game or simply gun game, is a shooter video game genre in which the primary design element is to simulate a shooting gallery by having the player aiming and discharging a gun-shaped controller at a screen. Light-gun shooters revolve around the protagonist shooting virtual targets, either antagonists or inanimate objects, and generally feature action or horror themes and some may employ a humorous, parodic treatment of these conventions. These games typically feature "on-rails" movement, which gives the player control only over aiming; the protagonist's other movements are determined by the game. Games featuring this device are sometimes termed "rail shooters", though this term is also applied to games of other genres in which "on-rails" movement is a feature. Some, particularly later, games give the player greater control over movement and in still others the protagonist does not move at all. On home computer conversions of light-gun shooters, mouse has been often an optional or non-optional replacement for a light gun.
