We just received intel that there will be a week of Call of Duty: World at War double XP beginning December 5th, but that it's semi-exclusive. Only World at War collector's edition purchasers will have access to the XP fun. Those who registered their World at War CE copy (register it here) will have access to a special "Officer's Club" playlist that'll award twice the XP and (hopefully) twice the fun. Remember, the week of two-times XP begins December 5th and wraps at 11:59AM pacific on Friday, December 12th. At ease, soldier.
