CryEngine modders, start your, err, engines!

As of right now, CryEngine 3's SDK (software development kit) is completely free for non-commercial use. Free is always good, especially when it's sure to lead to some brilliant user created projects, which will also have to be free. Crytek is of course hoping to secure a slew of new enthusiastic and CryEngine endorsing developers with the release, and they undoubtedly will.

"The award winning SDK provides the complete game engine to create AAA quality next generation games for PC, and includes the CryENGINE 3 Sandbox level editor, a production-proven, 3rd generation 'What you see is what you play' (WYSIWYP) - tool designed by and for professional developers."
