Allowing you to change colors while insight or behind walls, seeing what weapons they have, health, name tags and more the ESP doesn't need much more. I loved my experience with the ESP and honestly would pay for that alone if I wasn't bad, *cough* is worth it.
Safety 10/10
Now I'm not gonna bullshit you mainly because I do not fucking know how great the security is due to me only using it a couple days, but from feedback and what I see within the community it's really a safe software to use. Many use it on their mains from what I've read up on and I'm not afraid to either.
Easy to setup, easy to use, free spoofer cheap.. why wouldn't you buy?
