CoD4 gets double XP this weekend, Variety maps halved in price
Infinity Ward's Rob Bowling has confirmed that this weekend - September 13 and 14 - will grant Call of Duty 4 players double XP.
In addition, those of you that still haven't bought the Variety Map Pack will be able to do so for half price, or 400 MS Points, over the same period.
A PS3 version of the even is planned later in the month.
