The studio trumpeted recent additions to the toolset, including "Custom Executable Generation (CEG) technology" and support for in-game downloadable content.
"[CEG] compliments the already existing anti-piracy solution offered in Steamworks," explained Valve. "A customer friendly approach to anti-piracy, CEG makes unique copies of games for each user allowing them to access the application on multiple machines without install limits and without having to install root kits."
"As we roll out these features, we continue to look for new ways make PC games easier to create and better for customers to experiences," said Valve co-founder Gabe Newell.
The Steamworks toolset allows PC developers to integrate the various aspects of Valve's Steam platform into their games, including achievements, Steam community support, automatic updating, shared settings across multiple computers, and more.
