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.

Going through stacks of games for something old to play with someone new can deliver up some awesome experiences. But, in order to mix things up in the replay department I tend to suggest a cranked-up difficulty, which was the case recently with Marvel: Ultimate Alliance. With Marvel: UA, the hard difficulty mode has to be unlocked by completing the game, and is probably not explored by many people.

For me, the best co-op games are the ones that make me feel like a total geek while playing them. Left 4 Dead did this for me, since I was constantly remarking how it was like 28 Days Later, in addition to other obscure zombie movie references. The only way the co-op game can be any more fun is if I am surrounded by other people basking in geekery. Fortunately I got the chance this week, as I played a game that is essentially a perfect storm for geeks: Marvel Ultimate Alliance.
