Call of Duty: Black Ops Cheats :
Code - Get a ray gun from mystery box
by Unregistered Feb 23, 2011
when you find the mystery box in "kino der toten" go to it and open it. it's 950 to open it. then use the pistol you start out with, make sure its fully loaded and when you open the box shoot the middle it four times. then make you person lie down on there belly then pop back up and shoot it again four times then you should get a ray gun. I'm not sure if it will work for ps3 or for any other map.
I tested it and it worked for x-box 360
