If you don't have Team Fortress II yet, well,
WTF? Steam is now offering it free. I heard the only limitations are in the weapons drops, and trading features, so if you, or anyone you know might want to try it, now's yer chance.
They also just did a massive update, to all classes I believe, so I am gonna go check it out.
(Prettt freaking cool some companies still don't play EA "games")
