I just released the new version of my MapBuilder Editor. Have fun with it, of course for free

You can check also the pathfinder demo, whose development screenshots and videos I posted here earlier. It's inside the editor, you can control 120 units in 4 groups. Please note it is not a finished system at all, but works on any terrain, if no long walls or too large entities are placed. I would be interested in how fast or slow it runs on your pc...
