My son and I were trying to play Marvel Alliance online with my brother in Austin and could not get it to recognize both controllers. Can two people on one 360 play against someone on another 360? If so, could someone please tell me how?

I am not sure if two can play with one, but I know two can play on one xbox together. I don't see why you guys wouldn't be able to connect though?

cseaw: Your son might need his own Live account. I don't know if MUA allows "guests".

or you might need to resync one of the controllers to the xbox. that is all it sounds like. me and my cousin were able to play online on one xbox with other people online before
