MvM saved TF2 for me. It's much more fun than, say, 2Fort... Let me know if you need another player for your missions.
I have the following rules when I play: 1] You better be an AWESOME sniper or spy if you want me to play with you. Your Tours of Duty will be one indicator. 2] Experts do not need Medics; that's why we have a dispensor and sandwiches. 3] If after 3 attempts at a wave fails, then I'm out of there. 4] Ettiquette is a great thing.
