Black ops 2 Origins glitch: To do this you need a hord of zombies and the boss dude. Btw I found this by accident. Run a train with the giant dude and the zombies and get the giant to grab you with his claw. When hes pulled you in the middle of the zombies shoot the red button and he should let go, now you should be under the map, all you have to do is crouch and your done. Ps. Im not %100 sure it will work as this happened by accident but if you try tell me how it goes.
