Left 4 Dead
isn't the only zombie apocalypse out there--though you'd never know it from our current playlist

is blowing the doors of its Nazi Zombies game mode, completely unlocking the Co-Op Nazi Zombies playlist for Xbox Live and PlayStation Network public games...all without having to slog through the solo campaign.
Also, this weekend is a double-XP MP weekend (which actually started on Thursday, January 15).
