Xbox players have been getting their teeth into the Annihilation DLC pack for Call of Duty: Black Ops for a while now, but from today PC and PS3 owners can join the party, too, as the content pack has now been released.

Featuring four new areas to blow up friends and rivals in alongside a new Zombies level, Treyarch believes the new content is "mind blowing" and offers "four of the best Black Ops multiplayer maps." You can be the judge of that from today for 15 of your hard-earned dollars.

In celebration of the map pack being available for all platforms (excluding the Wii, whose proposed DLC for Black Ops has never materialized) the game's online modes on PC, PS3, 360 and Wii will be hosting a double XP weekend from tomorrow until Sunday.
