Easter egg: On disc 3 on the main menu screen, if you highlight and press the red 'JMC AMMO' button, this will show you picking up a bazookoid. Before firing the bazookoid, push one of the arrow keys. This will cause a light closer to the right side of the screen to light up. If you press enter, it will blast the code panel on the door. You are then taken to see a very funny Red Dwarf Trailer.
