In perhaps the greatest April Fools deal around, Bethesda today announced one helluva offer for Xbox 360 owners of Oblivion.

Today and through next week all of the Oblivion DLC will be half price. That means Shivering Isles is only 15 bucks, Knight of the Nine is only 5, the Vile Lair a measly 94 cents. The one catch? Horse armor has been doubled and is now up to five bucks. Oh, those guys at Bethesda.

All of that content is easily worth it (and quite honestly, more bang for your buck than the Fallout 3 content thus far) so check it out through the Xbox marketplace.
