This week's Xbox Live Deal of the Week features a piece of DLC for Marvel Ultimate Alliance. The Heroes and Villains pack adds four new heroes and four new villains to your game, usable in any game mode - including co-op.
The pack was originally 800
but is on sale for 400. Please note though, if you own the Gold edition of the game, there's no need to download this pack as the content is already included in your game!
