Hi I'm an FX artist at Trepang HQ and I accidentally turned the particle effects up so high the knob broke off and now I can't stop the shotgun from turning everything into coloured mist help me pls

It's probably the funnest shooter I've ever played. Unfortunately, I'm 51 and don't have the reflexes required to play it well, but it is fun as hell. I can't beat the last boss on Normal, but I'm trying.
