Not sure if this is the right thread, only just joined, bought the game, loved the original, love this one, only problem is i found a few bugs?! when playing Co-op, top screen (me) was driving the warthog, and there was no sound at all, (driving sounds) the sounds came back as i got closer to and or bottom screen (2nd player) was actually in the warthog, it was like it was only playing what 2nd player was hearing?
