I unfortunately don't' have the N4 books and don't know the back story. But just going by the name, the world they live on, and who they primarily go up against (PanO). Heavy/Light Rocket Launcher, Flammenspeers and Vulkan Shotgun totally make sense. But also I think Terrain Total would be one those cheap additions that makes them in tune with the story. There's not many HI with Terrain other than Orc, Aquatic and Suryat, Jungle. I'm not keen on them having Continuous Damage on weapons that don't already have it. But due to their armor I'd like the have Immunity to it.
