Well, the thing in the background of that picture looks like a crashed Command Station. Also:
None can stand before your modern weapons, but where do you use your limited ammunition? Do you resort to diplomacy, or native weapons?
This part is intriguing to me. It implies that there's an existing civilization on the planet which is probably not human, since all the humans were either wiped out, part of military force the player controls or contained within a nebula. Unless there's a sub-faction which split off and settled their own planet, and thus were not involved in the civil war which became the AI War, all branches of humanity are accounted for in those factions.
If they are humans who split off onto their own planet prior to the civil war, though, they must be capable of space flight and thus must have advanced weaponry. Although "native" does not necessarily mean spears and bows--they could still have space-age weapons, but the weapons that the AI War humans have are even more advanced, as the civil war led to a sort of arms race, quickening the development of new military hardware.
Or it could just be aliens. That would probably be the easier explanation.
I'm just wildly speculating based off of very little evidence at this point.
