Well Valve has finally given people who missed out on their Orange Box exclusive game: Team Fortress 2 an opportunity to jump in. Team Fortress 2 is now free to play (f2p) on steam. This is still the same first person team based game and no features were dropped to make the game f2p. Valve does offer Micro transaction on in-game items used to customize your characters but no purchase is necessary since most items can be obtained during gameplay. Check it out if you haven't already.
Available for Mac or PC. Get it here: Team Fortress 2 Download
