Microsoft have confirmed that the promised Call of Duty: Black Ops double 'Free Live Weekend' and XP weekend will start this Friday - 26th November ending on Sunday 28th November.
So far there is no confirmation of a similar event for PS3 or PC gamers. But previous MW 2 - double XP weekends have gone live across all platforms at the same time.
Because this XP weekend coincides with Xbox LIVE Free Weekend non Gold Members will get to play the game. This Free teaser could lead to more Gold subscribers (Microsoft hope).
