Dota 2 out of beta, heading to OS X and Linux
 

After two years in beta, Valve's wildly popular Dota 2 is finally finished—or, at least finished enough for an official release. The beta ended earlier this week, and you can grab the latest version of the free-to-play game right here on Steam. You won't be alone. Dota 2 is by far the most popular game on Steam, with over 321,000 active players I write this. Team Fortress 2, Steam's second-most-popular title, has less than one sixth the players right now.
