Back Track is a first-person shooter that was released for Windows PC in 1998 and for the Game Boy Advance in 2001. It is notable for being the first 3D shooter to be released on the Game Boy Advance.
Domingoaniax, an evil alien, has built up a large invasion force on the dark side of the Moon. The player assumes the role of special agent Jim Track, who has to rescue the 110 kidnapped humans and defeat Domingoaniax's droid army.
BackTrack's multiplayer mode has six deathmatch arenas, each playable as a standard 20-point deathmatch or as a 4-point round-robin. Both modes support up to four players via a link cable.
