first, all the AI weapons need to either be thor, or just cheat it and give them a longer range (like 2 sqares farther than thor) so you can pick them off like idiots. they also need to have better hp, dmg, and rate of fire than the player so it takes a big military effort to hurt them.
Second, the Ai need to rebuild and repair. not cheating build an repair like convecs warping in and stuff, a base that you can kill. it can cheat on ore or what ever (although it would be nice if it didnt).
Third, this is just a strategy suggestion, but the ai should make use of bottle necks, and in more open spaces should be a flat wall, not staggered or jagged. it will make them more effective.
I like the map idea, but i think every ore should be 1 bar, cause if ur gonna have crappy ore you might as well go all the way! and no magma wells b/c those are better than 2 bar rare.
cool map so far!
