It SHOULD work on non expansion as well as expansion so correct me if I am wrong. Load this in the editor, then edit the map and have fun designing!
Notes on high elevation:
Do not place buildings on the high elevation! It will muck it up! Same with using hekas, they will destroy the elevation. This means you can really have it on maps you can build on unless that area is unbuildable. Any units that "fall" down these steep hills will delete themselves! Very useful for deep pits that are not circular, etc. Only works if you fall in! You can still walk down the hill though!
Please comment on this download. I myself can't create random maps. This is an editted random map by M0ntly Python to serve this perpose!
