Call of Duty: Modern Warfare 4 Reveals Server Culling Anti-Cheat to Kill Wallhacks

Activision and Infinity Ward have unveiled Server Culling, a new anti-cheat system for Call of Duty: Modern Warfare 4 that withholds hidden opponent location data from player hardware. The technology launches across every multiplayer map, Combat Outpost mode, and Warzone on October 23, 2026, aiming to make wallhacks functionally impossible by denying cheat software the information it needs to operate.
