OK, it will sound very selfish, but I just love the Fulimn Prime.
It feels like a John Wick gun, with two firing modes, big FWOOM sound, and that slick design.

I am just surprised nobody worked on this one.
It could be a proto-fulmin, somekind of a tactical M4 platform with a silencer ; or a corpus-themed fulmin, with hologram sights and an animated barrel ; even a Kuva Fulmin could work fine, with a kuva canister in the front, tubes on the body, and the classic round design.

I know the gun isn't really loved by the community, but I can't be alone in thinking it would be cool to have a workshop skin for it.
If a 3D artist wants to take a go at it, I could even help with concept arts for free, just contact me on Deviant Art (Rayoru, same koala PP) .
