Unknown system: depends which one you're in, one of them has a couple planets that are interesting to visit, the other one is just there to look pretty, both of them have a group of 4 nomads come visit you every now and then.

I dunno about tekagi's base...are you talking about the tohoku system? I personally haven't tried going back there since I played the SP missions, not much worth doing there.

yes I mean the one through omicron alpha system that has nothing.
where is the other one?
because tohocu is locked I have a suspicion that somethiong interesting might be there (a 10 class turret perhaps)
anyway have you found anything else interesting?
very good game but i was dissapointed when i saw it was only 1 cd
too short scenario

Yeah, it's annoying that Tohoku is locked, especially since there's another base besides Tekagi's in there - Ryuku. I mean, they lead you there for like 5 seconds during the SP mission, tell you not to dock, and then you can never get back there again?! What kind of a **** programs that in??

There's nothing else in that system besides those 2 stations. You can't dock with the asteroid base because of a shield you can't penetrate. You can dock with the other one but it doesn't sell anything.
