Make them all look boring over time
Make them look really ugly
Massively screw over Crime Spree players, who need to be able to tell the difference between FBI, GenSec, and ZEAL MFRs
By installing this mod, you will find that aesthetic satisfaction and ability to identify key differences will increase by a whopping 1-250%!
Also gives GenSec a swanky new helmet that looks cool and gives you micro-orgasms every time you keep those helmets flying (Special thanks to EvilBobarino for providing the helmet)
