I don’t remember getting salvage, just the big payday. I’ve only done a couple of story missions beyond that one I think.
I did come across a K2 Catapult at Zathras??? I made the trip out there, the western most system and have been working my way back.
I did get 2 parts of it though. I saved it for last so I’d have plenty of time and morale for called shots and took his legs out. Still searching for more parts though.
