Aimbot
Aimbot for me, was the feature that i have liked more, because have 2 types of aimbot, the aimbot that u press an key and locks on the target and the other that i personally like more that is Silent aim that works when ur target is in the center of your fov, after that u just have to shoot and the shoot will hit ur target.
TriggerBot
This is the feature that i never use on cheats, i don't know why but i don't like this feature in any type of cheat!
ESP (Wallhack)
It's very good and has a lot of options for the cheaters xD
It allows to see behind the walls where the enemies are, where the turrets are if u enable the box of turrrets, you can have too on the rockets of the soldier, that makes more easy to dodge his rockets.
And of course, u can see where the enemie spy's are! :D
Security
The most important of every cheat, since i am on PA community (2017) i never used an hack that got detected, unless on CS:GO but that is a different story to tell.
Talking about the security on tf2, it has a big big security, the developers and blunt had made great job on this cheat and the other of course.
If Someone it's thinking on buying new cheat to try, TF2 it's good choice!
