The idea with this particular one is that the indigenous people (and there must be some, being that there is an alien biome) happened across Big Tony and regarded him as a deity, turned his selling base into a shrine. Then the base was attacked by the usual group of marauders, and the native having fled left Tony in danger. Pretty lame I know, but the base is cool.
I think it would look a lot more visually compelling if you were able to retain the little tech in the hand. Even if you have to keep it attached (and just forego using Bolts at all). Players aren't going to notice him otherwise, when deployed from a distance, with everything else going on in the mission, hills/scenery in the way, etc.
Nit-picking the crafting aspect, I might add another 1 or 3 Refineries on the other corner(s). Not that this is supposed to be a practical tech.... So whatever.
