Zero Tolerance was developed by Technopop and published by Accolade exclusively for the Sega Mega Drive / Genesis video game console in 1994.
One of three first person shooters released for the console (the others being Bloodshot and Duke Nukem 3D), Zero Tolerance is made up of 40 levels extending across three independent areas, a space warship called Europe-1 (an abandoned merchant freighter), the heavily fortified central command building for the Planet Defense Corps, and the sub-basement areas of that building. Your main objective in the game is pretty straight forward. Kill everything that moves and then advance to the exit. Normally this is either a staircase or elevator leading down to the next level.
