Mazantics is a single screen shoot 'em up with multi-directional movement similar to Robotron but without dual stick controls. The objective is to survive as long as possible through an endless amount of randomly generated mazes. The mazes are populated by humanoids who chase the player and if they manage to catch him, a life will be lost. The player has to shoot all humanoids to complete a maze and progress to the next one. It is possible to play with manual fire or with auto fire, where the player character automatically fires when an enemy appear within his line of sight. Enemies get progressively smarter and will after a few stages start firing fireballs that have to be dodged. The player has three lives and an additional one is given at 20,000 points.
