Hey , does anyone know how to use this hack ?

i know how to use radar and infinite spawn , that's all

can you use rapid fire or aimbot in PVE ?

https://perfectaim.io/forum/topic/29025 There isn't rapid fire. Also yes you can use aimbot in PVE. It's more safe to use misc in PVE as well then PVP since you can be reported. Play smart and hope you like the cheeto.

If i remember correctly it used to have rapid fire but it was removed due to it being very risky and likely to get you banned.
