It's a quick mission builder with tons of options and functionality. Works for online and offline maps.  Looks like some a great piece of software for map builders.

...Good to see that Seeker posted the link to this. UberDemon's map builder is the one that I used to use to build maps on the fly in IL2 way back when. This version is the "New and Improved" version of the beta that I was using. With this version you can make your map...then it saves three versions...if I am not mistaken of the same mission. Coop, D/f, and stand alone....gonna have to read the docs to make sure. At any rate...this is a must have piece of software for the serious (as we all are) IL2/FB pilot.....just my two cents worth..Rocky...TX-CUDA on UBITX-CUDA on HyperLobby
