What do you do after recieving the death machines in cod black ops zombie ascention?

After you save the mystery man and receive the 90 second death machines, there is a part where the screen goes black and white and you can hear a howl/scream and if you listen very closely after that you here Sam? Or someone say "Try to find me". The Easter egg can't end there why would Treyarch make you do all that for nothing? The Easter egg can be clearly referenced to the escape plan of Vorkuta, Step one: secure the keys= get enough money to open doors. Step two: ASCEND from darkness= turn on power and get rid of black and white. Step three: rain fire= blow up rocket and make it rain fire. Step four: unleash the horde= horde of monkeys. Step five: skewer the winged beast= Skewer the words to spell LUNA. Step six: wield a fist of iron= wield 90 second death machines. Step seven: raise hell= wtf??? Step eight: freedom!= epic win?!?!?!? Okay here were some fail solutions that don't work. Pack a punch the death machine does not work. Shoot the car batteries does not work. Shoot the lock on doors does not work. Does spelling HYENA do anything instead of spelling LUNA and what about spelling HITSAM? And for those PC users who no clipped out of map of course you won't find anything, if Treyarch is smart enough to make an epic Easter egg they are gonna now that PC users are going to no clip. I need an answer!
