Berzerk (revision RC31A) is an arcade classic that first hit cabinets in 1980, developed and published by Stern Electronics. This particular build is a revision of the original game, often found in emulation collections. It's a maze multidirectional shooter, a genre that was still finding its identity in the early days of arcade gaming. The game puts you in control of the Humanoid Intruder, a stick figure trapped in a series of dangerous rooms. Each room is a simple maze filled with slowly advancing robots that fire lasers at you. Your goal is to shoot all the robots or find an opening in the wall to escape to the next room. But there's a catch: a bouncing smiley face named Evil Otto appears in each room and relentlessly chases you. Touching Otto kills you instantly, so you have to balance shooting robots with staying out of his path. The rooms are randomly generated, so no two playthroughs are exactly alike. Berzerk is worth revisiting today because it captures a raw, unforgiving arcade experience. The robot speech synthesizer ("Intruder alert!") and the tension of Evil Otto's chase make it memorable. Compared to other early shooters like Space Invaders, Berzerk demands constant movement and situational awareness. It's a simple game but one that rewards quick thinking and pattern recognition. The revision RC31A doesn't change the core gameplay, but it's the version many emulators default to, so it's a faithful representation of the original arcade release.

How to play Berzerk online

When you start a game, you'll see a maze room with robots scattered around. Use the arrow keys to move the humanoid in eight directions. Press the S key (B button) to fire your laser gun in the direction you're facing. Each robot you hit explodes and disappears, but they shoot back, so stay on the move. Evil Otto appears after a few seconds and bounces through walls, always heading straight for you. He cannot be destroyed, so you have to escape through an exit that appears on one side of the room once most robots are cleared. The core loop is straightforward: enter a room, shoot robots while dodging their fire and Evil Otto, find the exit, and move to the next room. Your score builds with each robot killed and each room cleared. If you die, the game ends unless you have credits. There are no continues or saves; it's pure arcade action. Take note of wall patterns and robot positions, as rooms are randomly generated each time you start a new game. Quick reflexes and a good sense of spatial awareness are key to surviving.

Berzerk FAQ

Does Berzerk have a multiplayer or co-op mode?

Berzerk is a strictly single-player arcade game. There is no cooperative or versus mode; you play alone as the humanoid trying to survive each room. Some arcade cabinets allowed alternating play for high scores, but that is not the same as simultaneous multiplayer.

Is Berzerk exclusive to Arcade or did it appear on other systems?

The arcade version by Stern Electronics is the original, but Berzerk was ported to several home platforms including the Atari 2600, Vectrex, and later compilations. The revision RC31A here is specifically the arcade ROM, not a home conversion.

Who developed Berzerk?

Berzerk was developed and published by Stern Electronics, an American company active in the early arcade market. The game was designed by Alan McNeil, who also programmed the speech synthesis that gave the robots their iconic taunts.
