Anti Cheat Free | Keep hackers & cheaters away | v2026

📄 Documentation 💬 Forum ▶️ Demo 🟣 Discord

Ship your game. Keep it fair.

Once your game is on a player's machine, its memory and its saves are theirs to edit. Cheat Engine searches for 100 health and writes 9999. Someone opens the save and types a new coin count.

GuardingPearSoftware's AntiCheat Free runs inside the build, hides those values, and notices when someone touches them and lets you decide what happens next.

✔️ Hide health, score, and coins from memory scanners

✔️ Make an edited PlayerPrefs save fail on the next read

✔️ Notice a rebranded Android or iOS build

✔️ Keep your code – swap the type, not the logic.

Trusted by developers for 10+ years.

Your game is ready to ship. Is it ready for Cheat Engine?

👀 SEE IT IN ACTION

Prefer to test the result yourself before downloading? Grab the demo builds and give them a try.

🔒 HOW YOU ADD IT

1. Import the package. The full C# source is in it.

2. Drag the AntiCheat-Monitor prefab from GUPS/AntiCheat/Resources/Prefabs into your scene.

3. Swap the values a cheat tool looks for.

ProtectedInt32 health = 100;

ProtectedVector3 position = transform.position;

ProtectedPlayerPrefs.SetInt("coins", coins);

Read, write, and math stay the same. Open the memory demo if you want to see how a plain int compares next to a protected one.

🧠 WHAT FREE STOPS

Cheat Engine and tools like it search for the number they can see. Protected values hide the real one and put a honeypot beside it. If someone pokes that trap, PrimitiveCheatingDetector fires.

You get protected versions of the everyday types: int, float, string, Vector, Quaternion, and the rest. ProtectedInt32, ProtectedFloat, ProtectedVector3, ... with the same operators you already use.

Unity PlayerPrefs is a text file with a friendly name. ProtectedPlayerPrefs writes still to the same place. But it hashes the key, encrypts the value, and calculates a signature. An edited save fails that check on the next read.

If someone republishes your Android or iOS build under a new package name, MobileGenuineDetector notices.

When a check fails, the report lands on the AntiCheat-Monitor. As reaction a punisher could close the game. You can also hook a UnityEvent on the detector, or subscribe in code.

⭐ IF YOU ALSO NEED PRO

Free is enough for the number in memory, the save, and the package name. AntiCheat Pro covers also:

- A speedhack that scales deltaTime

- A device clock moved forward to skip a daily, a trial, or a cooldown

- An auto-clicker or macro (Unity 6 and the Input System)

- A tampered list, queue, stack, or ordered chain of scores

- A modified Android app, including installs from unofficial stores, altered files or signatures, extra libraries, or detection of known cheat tools like GameGuardian

- A jailbroken iPhone or iPad

- BepInEx, MelonLoader, Harmony, Doorstop, or MonoMod

- A debugger, or the game running in a virtual machine

The types you already swapped stay.
