Cursed Level secrets
1. When you are in the swamp near the skull that's on the base of the wall there is a lift taking you to the top of the level where you will find some wooden beams to walk across. There is a gap in the middle which you must jump and then continue along the wooden beam to what seems like a wall. Carry on and you will disappear through the wall where you will find some goodies(tip, This is a great place for camping when playing split screen with your mates, Just wait for them to come near and surprise them from nowhere).
2. There is a walkway with holes in the floor and two skulls either side at the top of the entrance to it.
In the room before this with the two health pickups and the fallen down rocks you'll notice a section on the wall has a square outlined in it. This is a door in wich you'll find a Double Damage behind. take out your trusty assault rifle and shoot the block it lies behind.
