I was messing around with weapons skins today and decided to share. I swapped the mechgun model and textures with the Suppressed Gun model and textures, and got a pretty cool result!
I also swapped the sound for the Suppressed Gun sound effect.
My charge Gatling looks like this when I did this.
Note to players with modified common.pac files. Swap file 42 and 96 with PAC Manager.
Credit to @Spicy McNoodle for helping me out with what sound file the mechgun is. Suppressed gun was easy to find. ha
