Berzerk Cheats

When robots shoot horizontally, any shot the hits your character in the space just below the head will not cause damage.

Use this trick on any level that has a top door. Approach the door until your character's head is just out of the door, but not enough to cause your character to exit the room. Wait for Evil Otto to appear and press Select (or move around so Otto does not get your character before getting to your left or right side). Otto will disappear out the door before a "laser beam" shoots to the bottom of the screen. Otto will "smash" through the wall below and float, not bounce, towards your character.

Press Select while a robot is exploding to display a random six-digit number at the bottom of the screen.

Never run from Evil Otto along the bottom of the screen. Otto will take smaller bounces and outrun your character.
