Escape from the Planet of the Robot Monsters Cheat - Pass through doors: --------------------------- This cheat only works in a one player game. In-game when you reach the Reptilian monster, run past it and stand in the centre of the join of the gates that block your way. When here waggle the "joystick left" and "right" and keep dropping bombs. In a few moments you'll go 'through' the doors and appear on the other side.
