Myself and Antony had a good, if not brief blast last night, I feel I need some more practise though, was a bit hectic for me, maybe I'm too used to onslaught in UT2004.
XFIRE worked in the sense that we could talk to each other and organise a server etc, I even wandered off into a CS match, and was still getting messages from Antony even though he wasn't playing.
I'm up for another stint tonight....
What other games have people got loaded? currently I have Doom3, HL2, and UT2004
