Forum:Anyone wanna go through the underdome?

Hi guys. I just bought the Underdome today since it was only 5 bucks. I beat the Prove yourself mission and got the skill point. I know that a lot of people hate the bigger challenges or whatever they're called, but if someone wants to go through them with me, and make it not as boring, feel free to tell me and I'll send you a friend request.

Oh yeah, almost forgot... I am on the 360
