I'm going to post my review honestly while also adding a disclaimer from my experience with proofcore.
(This review is slightly dated since it's been a few months since I used the cheat, I just completely forgot to make this post, things could have changed.)
I've been a member of proofcore for a few years, I've used their Rogue Company cheat in the past when that game was relevant, it was decent. As of recently I came back to try their Overwatch cheat so I'm here to review.
ESP: 10/10
Reason: The ESP is well made, it's clean and functions well, not much else to say here.
Aimbot: 5/10
Reason: Not very legit, while I've heard it's possible to configure it to be really legit I haven't had much success with it. Most configs shared by other users are semi rage configs. And any "legit" configs are barley noticeable assistance but not for good reasons.
[Warning]:
While I do make this review in good faith aside from my poor experience with the cheat I do want to put this out there:
I was blacklisted/banned from proofcore by their "security system"/anti crack measures despite not trying to crack or debug the program. I had opened a ticket in the past, even mentioning support in the server however I was not given a proper explanation or way to appeal this.
I imagine this won't affect most people who do not do developing/reversing on their own time, however I would recommend not having any debugging/development tools installed or running while using the proofcore loader.
Would have wished I could continue to use proofcore, especially since I lost nearly my full month subscription to this, however it is what it is and I ultimately use other providers now.
