Valve heeft de tweede versie van de SDK voor Half Life aangekondigd. Hiermee is nog meer te Modden en is het nog makkelijker om te Modden."MODs such as Counter-Strike will benefit enormously from the new SDK," said Counter-Strike co-developer Minh Le. "Half-Life is far and away the best development environment for MOD authors, in addition to having the largest on-line community. With Half-Life, you can build a better MOD and have it played by a lot more people."This release of the Half-Life SDK includes all the a ets available in the "ProSDK," previously only available under NDA, plus many new features, including acce to Valve's new networking system, and new user interface toolkit (V-GUI). Half-Life SDK 2.0 will be made available free of charge on gaming Web sites and CDs everywhere in the coming weeks.
