In case you haven't seen the most recent blog post from Valve, TF2 is now available to Mac users. In celebration, you can get the game for 10 bucks...
OR just play it free for the weekend.
Good stuff. PM me for a friend request if you feel like playing (or want to bag me a set of earbuds, since my mac can't launch tf2)
Where do yo ugo to download it free for the weekend? I'm not seeing a download link...
