"Xeno" was an assault rifle that was due to be released with a Hollywood mansion heist, codenamed "Holly". For unknown reasons, Holly was scrapped, so Xeno was never released.
Despite this, textures, animations, and an icon for the gun leaked, allowing for this recreation mod to be made.
Features
It's basically the Pulse Rifle from Aliens!
