Escape from the Planet of the Robot Monsters
Cheat:
------
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.
