lulz @ you if you actually believe that was him and not some pubtard aliasing. The same 30 or so people play TAM and that's it, and most of them use a different alias every game and every server.
Fat doesn't play UT. At all. He stopped
very early in UT2004 just like everyone else who was in it for the money, because the money just wasn't there. He doesn't play UT3 either because, naturally, there's no money in a dead game no one plays that is also completely unfit for competition.
Notice how it doesn't say he'll be the one teaching? Because it won't be him. He's just got his name on it so it'll sell better. He's little more than a figurehead -- a brand name -- now. I'm guessing he doesn't game at all anymore. He's a 1v1 player and there are no 1v1 games out right now that anyone gives a crap about.
Additionally, since this "camp" will also teach how to mod UT3, I'm guessing these "professional" gamers who will be doing the gameplay stuff are the same guys doing the modding stuff. I seriously doubt they'll even know WTF they're talking about when it comes actually being good.
