On the subject of guns, try to secure outcast guns and a MR, afterall, outcasts are neutral to the nomads, so it would make sense more than civilian guns.
Actually, if you stop in at Mactan and buy Hellflurry MKIIs, you get some pretty Nomad-looking guns right there.
And considering that you start with the ability to dock and buy...
That's what I did with my trial, at least.
I thought that it looked more like Nomad guns that the rest of the weapons out there.
