Valve has announced that a new set of advanced features has been delivered in Steamworks, a complete suite of publishing and development tools that are available free of charge to developers and publishers worldwide. Headlining the new feature set is the Custom Executable Generation (CEG) technology that compliments the already existing anti-piracy solution offered in Steamworks. 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 on their PC. The new features also include support for in-game downloadable content (DLC) and matchmaking. The in-game DLC support allows developers to deliver new content as they choose (paid or free) from inside the game itself, allowing users to make immediate purchases and experience the new content in the same game session.
