First rule, if you are playing Tummy Sticks, you have to have the Dildo equiped as your primary weapon and it needs to have anal penetration unlocked. JK!
I have only done quickscoping battles. The rules I have typically seen and played with are these:
Primary: Intervention only
FMJ or Thermal only
Secondary: doesnt matter because you cant use it
throwing knife allowed (think it depends on who is hosting it)
No stuns or flashes
Health either half or full
Perks doesnt matter (you will see snipers use commando pro for the ability to jump shot or whatever you call it from high distances, like on top of the tower thing in Rust)
I am not a pro, my K/D isnt even over 1.0. So dont take this advice as written in stone. This is just what I have seen. I heard on the optic gaming website
You must login or register to view this content. there is a list of GB rules for playing against them. I cant get to that website since im on a government computer and the word "game" is in the website (retarded). Hope this helps some what man. If you are ever interested in a 1v1 quick scope my PSN is The_swede27. My vagina does not bleed if I lose! Cheers
