Thank you again Xero for bringing the latest CS news to my attention.
Pre-loading of the Counter-Strike: Source beta to cyber cafés begins today. On Wednesday, this first phase of the beta will open and the game will be playable at all cyber cafes that subscribe to the Valve Cyber Café Program. Later this month, the beta will be extended to owners of Counter-Strike: Condition Zero and ATI Fulfillment Coupon holders.
This beta serves as a compatibility test of the Source engine as we near the completion of development on Half-Life 2 and Counter-Strike: Source. During this limited-time beta, issues can be reported using the in-game bug-reporting tool. In addition any crashes will automatically generate a report back to Valve's bug database. We thank everyone for their participation, and we hope Half-Life 2 and Counter-Strike: Source live up to your expectations.
