So I've heard people talk about the perks for hero/bandit skin in the past and I was wondering if they were myth or real. What I've heard is bandit skin is + some percent change of ammo spawns, and some other stuff. Hero skin supposedly gives better food drops and the vest on the skin gives a 30% bullet damage reduction and faster run speed. So is this a myth or is this real?

so it doesn't do anything? Thanks man.
