• background threads-friendly (to avoid IO hiccups)

• simple and easy to use Player Prefs-alike API wrapper

▶ Obscured File & Obscured File Prefs tutorial

📌 Code Hash Generator

Generates a code hash signature to compare against the current hash and make sure the compiled code was not altered.

Provides hashes for both whole build and separate files in build (helpful for aab Android App Bundles).

Uses background threads to calculate hashes, keeping CPU footprint low.

For Windows Standalone and Android only so far.

📌 Android App Installation Source Validator

Makes you aware from what source your game was installed, be it Google Play, Galaxy Store, manual installation via Package Installer or something else.

📌 Speed Hack Detector ▶ tutorial

Makes you aware of nasty cheaters trying to slow down or speed up your game.

Correctly reacts to the time glitches.

Allows to resist speed hacks with SpeedHackProofTime class.

📌 Time Cheating Detector

Uses Internet connection to get reliable time.

Reacts on both incorrect system time and actual cheating during or between sessions, allowing you to catch people who changes time to speedup long-term processes (like building process, energy restore, etc).

Works with weak internet connection.

📌 WallHack Detector ▶ tutorial

Covers 3 common types of wall hacks:

• shoot through the walls

• walk through the walls

• look through the walls

Uses generic sandbox approach allowing to detect unknown cheats.

📌 Injection Detector ▶ tutorial

Reacts on foreign managed assemblies both injected at runtime or into the build. Doesn't cover non-managed (native) injections.

📌 Third-party plugins

• actions for Opsive's Behavior Designer

• actions for PlayMaker (except obscured types due to PM limitations)

• works great with Simple IAP System to validate IAP receipts

• works great with Cross-Platform Native Plugins to save into the cloud, setup leaderboards and more!

• used in Lovatto Studio MFPS Anti-Cheat And Reporting addon

• used in Stan’s Android Native asset

Complement your setup to resist reverse-engineering threat:

• Obfuscate names with Obfuscator

• Protect IL2CPP build with Mfuscator

📌 Overall highlights

Easy to start:

• detailed User Manual with examples and tips

• examples scene

• video tutorials

Easy to extend:

• full API Reference

• 🔥 full C# sources included!

Support and updates since 2013 💖

📌 Final notes

ACTk will save you a lot of development effort hours and bring handcrafted years of anti-cheat expertise.

Serves as a powerful tool in a professional hands if you wish to go further and build own ACTk-based solution.

A skilled and motivated cheater can break any protection, and thus it's not guaranteed your game will be 100% safe from all cheaters if you'll use this toolkit. Though most cheaters are not that skilled thus massive "casual" cheating can be eliminated for good.
