In space, no one can hear you scr... yeah, you know the drill. No one can hear much of anything actually, except for the groans of endlessly advancing zombies, and the choked coughs of machine gun fire.

Thankfully, Call of Duty: Black Ops's DLC zombie map "Moon" features an unlockable musical easter egg that dials in a healthy dose of ass-kicking metal to the proceedings. Activating it is a simple matter of finding a few teddy bears, which YouTube user TheMediaCows has been kind enough to share in the video above.

I like how excited his onscreen character gets that he's finally found the music. Though who can blame him? Space can get lonely sometimes. It's nice to have a decent soundtrack.
