Fun little set of video's that im working on just creating and playing around with Payday 2 Custom builds. Yes i'm using mods but these builds work fine on vanilla too.
Obviously I haven't stayed fully true to the Default TF2 Sniper but I used the weapon catagories that he does use and I feel that I have done a fairly decent job at that.
I generally have a central theme with these builds too, the snipers being Damage.
Hope you enjoy it.
