Hm.. Did we ever end up playing any coop? I forgot. I think I ended up getting too sucked in by the single-player stuff.Xbox's EU (or EU primetime) was terrible even right around launch. Finding a group was as rare as rocking horse shit. Massive shame as the few rounds of co-op that I got into were pretty fun, especially with the different classes.
Would really help with some cross platform matchmaking ;)
