Sure, I havn't been on in the last few nights, but I do get on almost every night. I have a lot of friends that play halo though, so I can't promise you won't meet a few of them. haha. I don't know if I'm good enough at campaign to play it on legendary though. I've only ever done it with a group of people. (I can play it on normal just fine..)
No worries, I like to play with other people. The more the merrier
I haven't played Halo in months though so I doubt I could pull it off on legendary either. I would be warming up on Reach to get ready for Halo 4 but I sold it. I know, I'm stupid.
