I am currently working on an official Conitec level design tutorial that will not only teach you level design, but show you how to use Doug's new scripts so you can create a complete game including setting up panels, intro screens, level changes, etc.

The level design part will provide information, not only on level design and texturing, but also on planning and doing research for your game. I am not sure of the release date because a lot of the project depends on Doug's scripts as well as my finalizing the small game demo that will be a part of the tutorial.
