A relatively simple mod that adds a couple local modes to Mustafar, complete with unique weapons, gameplay, effects, and localization/names for the Mustafarian natives, the underrated bug people. Mustafar - Hunt Clone Wars features Clone Sharpshooters against Mustafarian Managers in a classic Hunt Mode. Mustafar - Hunt Galactic Civil War features a classic conquest mode featuring the Empire versus the Mustafarians.
As you can see, Mustafarians have names that are much more in line with the Mustafarian language, making them unique from other factions.
