I've uploaded a new handbook on mission building in CFS2. This is a true e-book at almost 230 pages and 15MB. It goes way beyond my earlier tutorials and covers not just basic mission building but advanced mission techniques, hand-editing, campaign building, etc. It also includes chapters on infrastructure, moving objects, weather, and other related topics. Even if you have my old tutorials or are an experienced mission builder I think you will get something out of the Handbook.
CFS2 is seven years old now but still going strong, and still picking up a few new players. I decided that with so much continuing interest it was time to update and expand my older works. Enjoy!
