Power - First turn on the power.
Bunny - Go back to spawn. Go up the stairs in the room with pack-a-punch. On the left when you get up there should be a skinny hallway with debris covering it. Aim your weapon into it at the bunny on the floor and eventually it will rise and go towards you. You will now be teleported.
Light Bunny - Now you should be in a very dark area. Look around until you see a purple glowing light. Shoot the bunny that is at the light. Do this three times.
Crate - Look around for you yellow light. The crate with the items will be there. There will be a lot of salvage, some equipment, guaranteed Juggernog, and a Chance the weapon will be a Rai-K or a Ray Gun.
