Here are some 3D renderings of the Flinger, Shotgun, Machine Gun, Rocket Launcher, Optical Rifle, Sniper Rifle, and teh Regulator.
These screens appear to have been pulled from a Korean Huxley site and are currently posted on a United Kingdom Huxley site. (The original pages can be found
here)
Since gameplay info states that all weapons will be completely customizable I am geussing these are the base models for the guns.
Upon further digging and investigative research I unearthed two more Huxley weapons. (Found at Huxley-Evolved, an American Huxley fan site)
The Inquisitor and the Discharger.
I also found a diffrent "class" of the Regulator.
This is some solid evidence to some sort of weapon evolution.
