Aye. Yes XBox Server.
You'll all need the Back to karkand map pack. I'm thinking CQ and Rush maps with the odd TDM thrown in.
Be a lot better (Play and connection) wise if we all had a single server to go.
Forza was lots of fun because we could all be in one party, and get to know everyone via chat. Having up to 24 of us all shooting the sh!te out of Shad everyone would be awesome fun.
I'll do it for 30 days to see how it pans out. If it's good then I'll extend.
