Anti-Cheat Toolkit
Protect what players earn. ACTk hardens the values in memory, the saves on disk, and the clock on the wall, so your leaderboard means something.
No client-side tool makes a game 100% cheat-proof, and we won't pretend otherwise. ACTk raises the cost of cheating far above what casual and semi-serious cheaters will pay. It stops the memory editors, save-file hacks, speedhacks and injectors that ruin most leaderboards. Determined attackers on a server-authoritative target still need server checks; ACTk is the client half of that story.

FAQ
Does Anti-Cheat Toolkit make my game 100% cheat-proof?
No, and no client-side tool can. ACTk eliminates casual and semi-serious cheating (memory editing, save tampering, speedhacks, injection) and raises the bar high enough that most cheaters give up. Competitive games should pair it with server-side checks.
Will it slow my game down?
Obscured types are near-free to read and write; detectors run on a light interval you control. You enable only what you need, per platform.
Does it work on mobile and IL2CPP?
Yes. All platforms, Mono and IL2CPP, with extras for Android like install-source validation and screen-recording prevention.
Do I get the source code?
Full C# source is included, so you can read exactly what runs in your build and extend it.

| Works offline / single-player | Yes | No |
| Drop-in, no backend | Yes | No |
| Protects a competitive economy alone | Pair with server | Yes |
Most games aren't fully server-authoritative. ACTk is the practical layer that protects the client where the cheating actually happens.
