If you have the Limited Edition PC version of Call of Duty: World at War, this weekend is all about you. As we reported last month, this weekend owners of the Limited Edition version of Treyarch's recent WWII shooter get double XP points in the game's multiplayer servers.

The Double XP time period ends at 11:59 am on December 12. If you own the PC Limited Edition version of the game you are already set to go since your CD keys are already been tagged as being part of that exclusive group. All you have to do is join an online multiplayer server and you will automatically get double the normal experience points for that time period.
