Berzerk

Berzerk is a 1980 maze multidirectional shooter video game developed and published by Stern Electronics for arcades. The game involves a Humanoid Intruder who has to escape maze-like rooms that are littered with robots which slowly move toward and shoot at the Humanoid. The player can shoot at the robots to try to escape the room. Along with the robots, a smiley face known as Evil Otto appears to hunt down the player within each room. The first game to be developed in-house at Stern, Berzerk was designed by programmer Alan McNeil. He slowly developed a game with robots at first, and then later added the walls and the Evil Otto character to expand on the gameplay.
