Its a mod for COD 4, just have COD4 installed and log into the game an it will DL the mod to you and auto rank you up. When playing when you kill someone you freeze them you can target someone or stand next to and hit F to unfreeze a team mate. 1st team to freeze all on other team wins that round. You play a set # of rounds.
I'm so down. I've never played the mod before though, and I'm not really familiar with the maps in MW1. In my experience, there really aren't any servers up for this game anymore, but if someone wants to put a game up and get some practice in, that would be great.
