Call of Duty: Modern Warfare 4 Video Reveals Major Change That Could End Wallhacks for Good
AI-summarised brief · reviewed before publication
Activision and Infinity Ward unveiled “server culling,” a new anti‑cheat system for Call of Duty: Modern Warfare 4, in a video posted to the franchise’s official channels on October 2, 2026. The technology adds occlusion layers to map environments, ensuring the game server only transmits location data for players visible to each client. Consequently, wallhack software that relies on hidden positional information receives no data, preventing cheaters from seeing opponents through walls. Activision said the feature will be active on every multiplayer map at launch on October 23, 2026 and will extend to DMZ, Combat Outpost, Warzone and future updates, complementing existing cross‑platform anti‑cheat tools. The company warned cheat developers that the change creates a “major new obstacle” and pledged ongoing improvements for players.
