You downloaded the beta, you don't need the ODST disc anymore. Just go to your Games Library, it'll be there.
I would be, if I had an xbox. I'll be getting one as soon as the local gamestops (buying a cheap yet reliable gamestop refurbished arcade system.)aren't flooded.
No custom games. But I have a pretty fun idea where we could set up however many staff members (maybe 4?), and then swap in 4 guys who invite us for a couple of games. Teams are of course mixed up randomly, so we get to play and then move on to some more guys... sounds fun?
All eight people change their language to something ridiculous and unused, and they usually get matched up, right? Though I guess that doesn't change the fact that we wont be on the right teams :/ --- mace, go cnc.
Er, we just run an 8 man party. Boot the 4 who aren't a part of the regular rotation every few games.
