They're pretty powerful weapons but each weighs 13 pounds too and they're not particularly accurate. They're all located in Goodsprings cave and so are the weapon mods. This fires with 40 damage at an even higher 540 RPM and comes in a nice crimson colour with cutsom red plasma bolts :) The Alien Plasma SMG (Jiralhanae), with the later sound also.This fires with 55 damage at a higher 495 RPM with the same magazine capacity as the former

The Alien Plasma SMG, with the later sound.This fires with 75 damage at about 450 RPM and has a 100 round magazine of electron charge packs - but this (hopefully) doubles to 200 shots with the recycler. Notes: The Fallout 3 companions in this are not perfect recreations appearance wise, but that doesnt really matter. Edit: Just for fun I made a mod where each base game companions fight each other. This mod brings some decision-making to putting together the perfect weapon. There is a huge variety of unique guns in Fallout: New Vegas, but the combat complexity usually boils down to using V.A.T.S. The Alien Plasma Rifle, with the classic sound. Narrative and likability wise, Id say that the New Vegas companions win. The mod adds dozens of attachments, sights, and other customizable addons to most of the weapons in the game.The models aren't great, I'm no expert 3d modeller (this is all stuff I learnt to do within the last week), but I thought it might be worth sharing since there's absolutely no alternative anywhere I've looked I got a massive hit of nostalgia recently, so I decided to make some weapons inspired by the Halo games.
