So, I worked on this. I built their in game support system (irc backed!), wrote a bunch of the web auth code, and accidentally once deleted the production user database from the secondary site (whew, disabled and re-replicated from primary).
It was a lot of fun and got me a trip to E3 back when it was the big thing.
It was an interesting concept because no matter what, you would play the american side and fight the terrorists. (you would look like a terrorist to the other team)
