Ok, I have received the death machines 3 or 4 times with different people each time. The only untested theory I have been told (by a random who was top 500 for rounds) once you get the death machines you need to hit all 4 of the hidden eggs through out the map (at the EXACT((as he said it)) same time). He said that the door beside the box location outside of pack-a-punch will open and their will be 1 wunderwaffe in there. Now I've played and been playing every zombie map since WaW and consider myself a veteran (I may not be the best player, but I have gained knowledge)
He also then proceeded to say he got a PPSH in KINO....thats when i called bullshit and deleted him off my friends list. He said he got it by shooting a pack-a-punched weapon at a hole in the ceiling infront of the pack-a-punch room.
and again this is just a theory but I am looking for a team to test it, heck everything else has been tried. (all my friends are sick of trying the easter egg) I personally believe the death machines are the end, but that just pisses me off if treyarch would do that...they are so useless at the point you get them since its always mid round with a crawler.
