Treyarch and Activision have announced that another Call of Duty: Black Ops Double XP weekend is taking place on September 2 through to September 5. The event coincides with the first ever Call of Duty event, Call of Duty XP, which runs on September 2 and 3.

As normal during the double XP weekends, you get exactly what it says on the tin: double XP in all your time with the game over the period. It's an ideal way to level up in double-fast time.

The Call of Duty: Black Ops Rezurrection pack for Xbox 360 arrived on Xbox LIVE Marketplace today, with its arrival on other platforms expected next month.
