As you guys voted for it here it is (albeit 2 days late, sorry). The Shasvastii weapons drop. When I was looking for dossier images of the other underlung weapons I found out that Shasvastii don't even have a light shotgun or light flamethrower in their arsenal, so I did the Boarding Shotgun to make up for the lack of weapons in this set.
Still a small one but life is getting on top of me at the moment so not a bad thing. Onyx next and then Tohaa and Morats after that. See you next week.
