I'm gonna assume it will be random. Like, your first mission might pay out a Gauss Rifle, your second just gives you +++-rated stock targeting module or something like that. Don't think it will affect stores either."New inventory items, including rare LosTech from before the fall of the Star League!"
I had a mod that slowly allowed for the resurgence of LosTech across the map as time progressed, felt really organic and natural. I hope this might be following that same idea?
How much LosTech was in the game anyhow? Medium pulse lasers, ER large laser, ER PPC, Gauss Rifle, Double Heat Sink?
Of those, only GR and DHS are truly worth something, the others are bad without DHS.
