Cheating in online games ruins the experience for everyone. Developers fight back with anti-cheat systems that detect suspicious behavior.
Popular tools include:

- Easy Anti-Cheat (EAC): Used in games like Fortnite and Apex Legends, it runs in the background to detect hacking software.
- BattlEye: Common in tactical shooters like Rainbow Six Siege and DayZ, it blocks known cheat signatures.
- Valve Anti-Cheat (VAC): Steam’s own system that bans accounts caught using cheats in supported games.
While these tools are effective, they can’t stop every cheater. Developers also use server-side checks to spot impossible gameplay actions (e.g., superhuman speed or perfect accuracy).
For players, the best “anti-cheat” is choosing fair play. Avoid downloading questionable mods, and report suspicious behavior to keep the community clean.
