Berzerk is a multidirectional shooter arcade game, released in 1980 by Stern Electronics of Chicago. Berzerk places the player in a series of top-down, mazelike rooms containing armed robots.

The player controls a green stick man. Using a joystick and a firing button that activates a laser-style weapon, the player navigates a simple maze filled with many robots, who fire lasers back at the player character. A player can be killed by being shot, by running into a robot or an exploding robot, getting electrocuted by the electrified walls of the maze itself, or by being touched by the player's nemesis, Evil Otto.
