Yeah, setting up a hidden menu or cheats can be cool, but honestly, it’s a bit of a hassle to do all that yourself. I’ve messed around with that kind of thing before, but for games like The Finals, I’ve found it’s way easier to just use something that’s already set up. I came across this site
https://cobracheats.com/the-finals-hacks-cheats-esp-aimbot/ and their cheats are pretty solid. You get stuff like ESP and aimbot without the headache of coding or whatever, and it’s worked well for me so far.
