In addition to creating environment models and textures, as well as working on some level population and lighting, Fish also took part in the creation of several weapons and weapon mods for Fallout: New Vegas, including energy weapons, the Plasma Caster, and La Longue Carabine.
↑Question: "Who made up all of the energy weapons?" Joshua Sawyer: "I tuned all of the EW stats (too low for a lot of them, unfortunately), but the EWs were modeled and textured mostly by Mitch Ahlswede, Paul Fish, and Aaron Brown."Question: "whose idea was it to include the plasma caster its awesome!" Joshua Sawyer: "Mine, but it's just the P94 Plasma Rifle from the original Fallout, so I can't take any real credit for it. Paul Fish modeled and textured it."Question: "I just wanted you to know, La Longue Carabine is the most beautiful gun I've ever seen in a video game." Joshua Sawyer: "Thanks, though all credit belongs to Paul Fish, who did the modeling and texturing. The offset scope was based on one we saw in a Clint Eastwood film (not the Sharps in Josey Wales -- another one I can't remember right now)." (Joshua Sawyer Formspring posts)
