This is cool... you can play Team Fortress 2, the full game, same as included in the Orange Box for free this weekend. The Team Fortress 2 - Gold Rush promotion is on. I played some Gold Rush last night and have to admit, it was pretty fun. I'm not sure what the details of the promotion are, other than you have to sign up for and install Steam, but it does sound like a good deal (as free things sometimes are). Look for 'arcterex' online and you can come and kick my ass :)
