Zero Tolerance is an Action game, developed by Technopop and published by Accolade, which was released in 1994.


Zero Tolerance is made up of 40 levels spanning three separate areas: the space warship 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. The object of the game is to kill all of the enemies on a level and then proceed to the exit, which is either a staircase or elevator leading down to the next level.


In the future, mankind has made great advances in interstellar travel and subsequently colonised the Solar System. The extrasolar settlements, research outposts, mines, commercial colonies, and spacecraft and space stations throughout the Solar System are protected over by a mighty, interstellar military conglomerate named the Planet Defense Corps.

As a member of the Zero Tolerance squad, the player character is ordered during the crisis briefing to infiltrate Europa-1 before it explodes. His mission is to completely eliminate the mysterious alien aggressor from within, and also the transformed humans of Europa-1 they have “infected”, in the next few hours to erase all evidence of the attack and the alien intruders.
