Zero Tolerance is a first person shooter developed by Technopop and Accolade and published by Accolade for the Sega Mega Drive in 1994. It is notable for being one of the few first person shooters available for the system, a demanding genre seen by many to be outside the capabilities of the Mega Drive's hardware. Another unique feature was the ability to link two Mega Drive consoles to play a two player cooperative game .

Gameplay

Gameplay in Zero Tolerance is similar to other first person shooters of the era, with the player controlling one of several characters navigating map from a third-person perspective, shooting enemies while trying to find an exit. (the player cannot continue to the next level without clearing all enemies) Unusually for the time however, the game contains primitive stealth elements as player can crouch, jump and has several different melee attacks such as punching and even flying kicks can be executed. Weapons include firearms and explosives such as dynamite and bouncing grenades. the player can hold only five items at a time, including weapons and inventory items. rooftop levels have snipers that cannot be taken out, and many of the HQ levels have security cameras that can be destoyed or avoided.

History

Legacy

Zero Tolerance and its unfinished sequel, Beyond Zero Tolerance, were released by the developers as freeware.

Rendering engine

In terms of technology, Zero Tolerance lies somewhere between 1992's Wolfenstein 3D and 1993's Doom - rooms two dimensional as the height never changes (although the player's height can change slightly), and maps are "boxy", with walls are rendered as textured, flat surfaces positioned at 90 (or, unlike Wolfenstein 3D, 45 degree) angles.

Floors and ceilings are not textured, but primitive skyboxes are introduced and if the player shoots a wall, the texture will change to a "damaged" variant, in effect creating primitive interactive scenery. Enemies are rendered as sprites, and, also impressive for Mega Drive standards, are scaled in real-time. Shooting enemies will also create "gibs" similar to more modern shooters.

The consequence of all this is that the 3D view is constrained to a small portion of the screen, with the rest being taken by the game's HUD. The frame rate and draw distances are also lower than in both Wolfenstein 3D and Doom.

Multi-Player

In a similar manner to the Taisen Cable for the Sega Saturn released months later in Japan, Zero Tolerance is the only known official Mega Drive game to support linking 2 Mega Drive consoles to play a cooperative game between two players using a proprietary link cable plugged into the Genesis second controller port. This mode required each console to be plugged to their own television and running their own copy of the game. The original 3rd party cable could only be obtained by sending off the order card which was included with the game. It is possible to build your own cable using two 9 pin D-SUB male connectors or a pair of 9-pin controller cables wired accordingly:- Pins 1 to 1, 2 to 2, 3 to 3, 4 to 4, 7 to 9, 8 to 8 (via cable shield or wire) and 9 to 7 (pins 5 & 6 are not used).

The cooperative game works very well with little or no apparent lag and since players can be damaged by friendly fire it is possible to have a death match of sorts after a level has been cleared of enemies. Further, all previously cleared levels will always remain cleared and can be accessed freely via elevators at any time.
