User blog:LegoMan25/Alien Easter Egg?

Hi guys, my best friend recently said that there was a easter egg in Kino Der Toten *Zombies*; he says that in one of the rooms, under a staircase, there was a barrel, and using a crack within the barrel, you can see a grey alien's head; when I asked him about the room, he said it had a metal staircase. Im not sure if this is true or not, but can somebody please verify this to be fact or fiction?!?
