Who needs a double XP weekend, when you can have a double XP week? Rockstar is giving fans of Red Dead Redemption's multiplayer modes ten days to start raking in twice as many experience points than normal. Starting today and going all the way until January 3rd, you'll get double XP for all activity in any online mode. The promotion is happening on both Xbox Live and PlayStation Network, so jump online and shoot some zombie bears or something.
