Zombies And Double XP, Man. What More Could You Possibly Want?

What better way to spend it than shooting up the undead in Red Dead Redemption's new Undead Nightmare pack? If you're planning on taking the game online, then you should know that Rockstar are celebrating all weekend with double XP. The fun will begin tomorrow evening (18:00PM in England apparently) and will run right through until Monday. Good opportunity to hit the game's top multiplayer level, no?
