Go to where the precision sniper rifle spawns, then go down the hallway to see a satchel charge. Pick them up and throw them at the wall across from where you collected them. The wall blow up and you can go in . Once you go in, you will see what looks like a hot dog cart. If you are playing with power ups, you will get them all; if not, you will not find anything other than the cart . Note: If you look at the walls there are three signs that read "Caution you have chosen death". If you try walking out of the room you will die. However, this is a good ambush location.
