A Valve lançou o seguinte comunicado sobre o lançamento do CS:S :

“…
Starting later this summer, Valve will be conducting a
limited-time beta of Counter-Strike: Source via Steam. The beta will first be open to subscribers of the Valve Cybercafé 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. For more information, please visit www.steampowered.com.
