Berzerk (Atari 5200)

"Intruder Alert!" warns the robot. You are the intruder in a hostile maze-like planet where even the walls are death to touch. Relentlessly pursued by robot gangs, you must pulverize these androids with your laser gun before they blast you with theirs. "The humanoid must not escape!" shouts the robot master. Evil Otto, as he heads toward you. How long can you survive such madness?
