Very sneaky avoiding the difficulties of modern projectiles.

Very neat.

An idea: the general factions should not be created equal. The corporations would have been responsible for only a few tasks - maybe "United Minerals" being a mining faction, "Thor Energy" for managing power sources like reactors (equivalent of farms since robots don't eat?), "Tektroniks Limited" an engineering firm (responsible for building other bots), and other things. Each having their own strengths, weaknesses, and units.

The ship AI (senate) can lead a coalition of smaller factories that follow the original plans and try to continue the work they were meant for. Which in the AI's mind involves subduing the deviant factories.

An expansion to this mod (hehe that's far away) could involve the humans arriving...

Can't wait to see how this turns out.
