Berzerk is based on the classic Stern coin-op game. The object of the game is to score as many points as possible by shooting renegade robots.
You play a character trapped in a maze of electrified rooms. Each room is inhabited by one to eleven robots. You must destroy or evade the robots as quickly as possible and move on to the next room.
If you stay in the same room too long, the bouncing ball Evil Otto appears and marches toward you. Evil Otto can move through walls and cannot be destroyed, so when he shows up you better have an escape route ready!
