We received a brief email from Valve Software, announcing that "limited-time" beta testing of Counter-Strike: Source will start later this summer through Steam.

The beta will first be open to subscribers of the Valve Cybercafe Program, and then extended to owners of Counter-Strike: Condition Zero. The next installment of the world's number 1 online action game, Counter-Strike: Source blends CS's intense teamplay with the advanced technology of Valve's Source engine.
