Time Crisis is a first-person on-rails light gun shooter series of arcade video games by Namco, introduced in 1995. It is focused on the exploits of a fictional international intelligence agency who assigns its best agents to deal with a major threat by a hostile organisation, which has ranged from criminals, terrorists and hostile military outfits, and mostly take place within fictional locations across the world. The arcade series differed from other light gun shooters of its time by incorporating unique mechanics, including the ability to duck into cover to dodge attacks and reload the player's weapon, and forcing players to complete battles in each level within an allotted amount of time.
