Do your units ever fight back? they just stand there for me... they get shot at, landed on, but they just stand there. is there a mod maybe, that will fix the AI for your units?

No mods, AI is hardcode, and yes, it sucks. That's not important, seeing as the engine is still being updataed.

actually the ai for me, has done some pretty cool things, like when i was playing my friend i was about to hit him with my ship and his guy being controlled by a computer actually shot me and pushed me off course

Yeah, but Data has the AI using a rather narrow vector to look for things, they cannot see behind them, and not too far forwards. So, unless you get in front of them, they won't do anything. (hell even then....)
