Hello @bvlcony,
1. I'm pretty sure it works on both the Steam and non-Steam versions.
2. Our cheats are internal.
3. You can use both Aim Mode and set a keybind for aiming, but using a keybind is generally better.
4. If you're referring to the Aimbot, then yes, you can enable or disable Visibility check in the settings. Keep in mind that the cheat is only Aimbot.
5. It depends on your playstyle and settings. We haven't got any detections since its release, our cheat is undetected, but not undetectable. We cannot predict what will happen tomorrow, as if we could, we would prevent it. You assume the risk the moment you decide to cheat in a video game, and we are not responsible for that. As long as you know how to play the game and avoid drawing attention to yourself, you should be fine in the long run.
