First open up the box then throw a grenade at the edge of the box but make sure the grenade bounces inside the box then bounces outside of it. After that you should get the thundergun.
For the raygun make sure you have the handgun from the beggining of the 1st level then. Open the box shoot the around the middle of the box 4 times then kneel down, then lay down then get back to kneeling then shoot the middle of the box again till you have waisted the clip then reload after that you should have the ray gun.
p.s:
you need to be quick while doing all this.
what you do is when you open it you shoot the lid of the box four times lay down then you stand back up and shoot four more times then you will get the ray gun or thunder gun or one LMG's
by going to the random box in zombies
