Activision Reveals Server Culling Anti-Cheat for Modern Warfare 4
Server culling uses built-in occlusion layers to limit the location data sent to players, targeting wallhacks across all launch maps.
Activision and Infinity Ward have announced a new anti-cheat system called server culling for Call of Duty: Modern Warfare 4, according to IGN. The system is designed to combat wallhacks by restricting the information available to players' clients.
Server culling uses occlusion layers built into the game's environments to limit the location data that servers send to players. By withholding data about opponents who are not visible, the system aims to prevent cheaters from using that information to see through walls.
The system will cover every multiplayer map available at launch in Modern Warfare 4. It will also apply to Warzone, the Combat Outpost mode, and future updates.
According to the companies, server culling works alongside pre-existing anti-cheat methods across all platforms.
Call of Duty: Modern Warfare 4 launches on October 23, 2026, for PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X/S. The game features changes to 2XP tokens and a villain played by Mads Mikkelsen.
