History of Zero Tolerance
Zero Tolerance was developed by Technopop and published by Accolade exclusively for Sega Mega Drive / Genesis video game console in 1994. It was one of the few first person shooters created for that console, along with Bloodshot and the Duke Nukem 3D port.
In the beginning of the game, the player is provided with a mission briefing and a selection of one of the five playable characters. Each character has a different specialisation, making him or her better at certain actions.
Zero Tolerance is made up of 40 levels full of enemies to shoot and weapons to collect. The goal of the game is to kill all the enemies on the level and proceed to the next stage by going to the staircase or the elevator. However, nothing stops the player from simply going straight for the elevator without eliminating all enemies. This will result in the game not giving any level passwords to the player until the area is finished. Once the player's character dies, it will be marked as "Deceased" in the character selection screen and will become unavailable for playing.
Due to the limitations of the hardware, the player's view was restricted to a fraction of the screen. However, the game provided the player with a minimap for easier navigation. The game featured impressive visual effects for its time and, by the smoothness and speed at which Zero Tolerance ran, was said to rival many low-end versions of Doom available at that time.
