Update: Xbox 360 owners will have to wait until tomorrow to play Borderlands add-on The Secret Armory of General Knoxx.
The PC and PS3 release on Thursday is unaffected.
Original story: 2K has announced that The Secret Armory of General Knoxx, the third instalment of Borderlands DLC, is due out this week.
Xbox 360 owners will be able to grab it today, in fact, for 800 Microsoft Points (£6.80 / €9.60), while PC and PS3 owners can access it on Thursday for $9.99.
General Knoxx ups the level cap, and promises new enemies, guns, items and locations. It will also be accompanied by a patch detailed on the official forum.
Look out for our review of General Knoxx soon, and in the meantime why not check back on our Borderlands review, or our reviews of previous DLC packs The Zombie Island of Doctor Ned and Mad Moxxi's Underdome Riot?
