At this stage there is no CoD 4 360 TOG Clan. We use to have an active group, but most have moved over to CoD W@W or other titles now.
This is not to say that we can't get another one started though. (Any TOGers interested please post here.)
Just out of interest, where are you based and what times do you play? For AUS gamers, playing against US / UK teams is hard due to times and lag issues (but not impossible). This being said, TOG is an international organization with players from all over the world, so we just may find enough players in your time zone. Keep an eye on this thread and hopefully enough 360 players have not traded in their copy of the game
If this does not get off the ground, check back when Modern Warfare 2 is released, there is major interest in this up coming title amongst our members.
Good luck, and hope to see you on the battlefield
