GSC Game World has released the multiplayer beta SDK for "S.T.A.L.K.E.R. Shadow of Chernobyl," giving users a chance to modify the multiplayer portion of the recent first-person shooter.

"For the testing purposes, we would like to offer you try out the beta version of the S.T.A.L.K.E.R. multiplayer SDK. It includes both the map creation and editing tools, and the complete source assets of one in-game level. Later all the nine multiplayer levels will also be introduced as source.

Within a week's time the official specialized web-site dedicated to mod-building will be launched. For now, we'd like to invite everyone over to our forum in the MOD section where you can post your feedback and recommendations on working with the editors, specify the bugs and operational problems found.

This said, we announce a call for moderators who would take the responsibility of organizing the community work in this direction, edit the documentation of the MODs created to bring it to a common style, work with tutorials and more. The volunteers familiar with mod-building - feel free to send your resume to anton@gsc-game.com.

That's not all, though. Once the MP SDK gets fully mastered, we plan to release the editor for the single-player mode of the game.
Wishing you creative success and looking forward to hearing from you!"

The 300MB SDK is available to download from GSC Game World or Worthplaying.
