Berzerk
Berzerk is a multidirectional shooter maze game, released for arcades in 1980 by Stern Electronics of Chicago. Berzerk places the player in a series of top-down, maze-like rooms containing armed robots. The Astro Date is 3200 and you are the last survivor of a small group of earth people who came to explore the planet Mazeon. Soon after landing, you discovered the planet is a dark, apparently uninhabitable place. But by then it was too late to turn back because your space craft had been destroyed by Automazeons. This version is for all ColecoVision consoles, no SGM required. Game play is a replica of the arcade, including the full original maze layout and robot placement logic.
