If you haven’t hit that 15th level of prestige yet then now is your chance to get yourself even closer to a gold gun and a colored clan tag because as of right now until March 7th (Monday) there will be double XP for everything that you do in Call of Duty: Black Ops. This is regardless of whether or not you purchased the First Strike map pack.
This double XP weekend coincides with the fact that the First Strike map pack is now available for the PC and the PS3 and also marks the second time that Xbox 360 users have a chance for have double XP. Regardless of this fact it certainly seems like a lot more people will be getting shot this weekend by an M16 across the map.
