Zero-5 is a shooter video game developed and published by Caspian Software for the Atari STe in 1994. It is one of the last official releases for the Atari ST after being discontinued in 1993 by Atari Corporation. Zero-5 was well received by video game magazines and commended for its 3D graphics, sound, and gameplay, but was criticized for the constant disk swapping if players did not have more than one disk drive to be used when playing the game and sold very few copies. In 1997, it received a remake by the same team for the Atari Jaguar under the same name.
