About Zero Tolerance
The space station Europe-1 has been overrun by aliens. During one of the fights the nuclear cooling system has been damaged, resulting in a meltdown within hours. Your mission, as a team of five of the toughest persons in the Corps, is to infiltrate and gain control of Europe-1. You must sweep the entire station clean of aliens. Zero Tolerance is a first-person shooter. It is required that you kill every single alien on each of the levels (hence the name). The five members of your team, who have different skills, start out with different weapons, and are your five chances of seeing this through.

A scrappy but tense first-person shooter for the Genesis with a link-up mode, priced about the middle of the US carts.
Zero Tolerance is a first-person shooter developed by Technopop and published by Accolade for the Genesis. It came out in North America in October 1994 and in Europe in 1994, and it was one of the few first-person shooters on the system.
Mean Machines Sega praised its hunt-and-kill atmosphere and details such as recoiling corpses and blood-smeared walls, but found the presentation scrappy and the link mode underdeveloped. Computer and Video Games, reviewing it for the Mega Drive, praised its tension, weapon variety and huge levels, and liked the two-player link-up. Electronic Gaming Monthly's four reviewers reacted differently, but generally agreed that it was an effective stand-in for Wolfenstein 3D and Doom on the Genesis.
How it was made
A sequel, Beyond Zero Tolerance, was in development at Technopop for the Genesis but was cancelled.
What the press said at the time
| Electronic Gaming Monthly | 9/10, 7/10, 6/10, 8/10 |
“Three important factors that go to make a good game are tension, action and addictive gameplay, and although Zero Tolerance is a simple enough concept, derived from the laudable Doom, it's got the former in abundance.”
“With the added bonus of a very smooth and realistic first-person 3-D perspective, the action and atmos¬ phere go together like a baby and its bottle.”
Undated scores are from the review table in the game's Wikipedia article, limited to reviews of the Genesis version.
Before you buy
Among US carts it sits about at the middle, and the risk of a fake is low. The European cart usually costs less than the US one, loose and complete. A complete US copy means the case, cartridge and manual.
