DO THIS, ILL GURANTEE YOULL GET COLLATERAL (IVE HAD 4 IN 1)
i dont know all the game modes that this works coz i only play TDM, im pretty sure it works in domination and ground war and s&d
MAP: Highrise
GUN: Intervention w/ FMJ
PERKS: Any as long as you have stopping power pro on perk 2
As soon as the match starts go outside, BUT before you break the glass stay there, look through the glass into the enemy spawn and you can see eveyone knife the window and if your quick enough you can get 2in1 or like me 4in1...its simple
heres a vid if you dont understand
