Alright, here's my attempt at using the system VK made. I'm using a ten-scale since its simpler.

[quote]Rivet Gun Specs:

DMG: 6/10 (Might take a bit to drop someone)
CAP: 7/10 (Plenty of rivets = plenty of death)
ALT: 5/10 (It can go boom)
ROF: 8/10 (Spray and Pray and Kill)
REL: 8/10 (So simple a necromorph could do it. Hopefully they don't)[/quote]
