It's been a long time since there's been a major content or features update for Counter-Strike Source but today Valve has released a new beta version (via Steam, natch) of their classic team-based multiplayer shooter that has a ton of new features and additions. Once the beta test is complete the new features will be added to the regular edition of the game.

The beta, which was developed with the help of Hidden Path Entertainment (Defense Grid The Awakening) includes a new domination and revenge system, a new end-of-round display (including "interesting fact about a player") new lifetime player stats, and the addition of 144 Steam achievements.
