Activision says Call of Duty: Modern Warfare 4 is getting a new anti-cheat feature called Server Culling, aimed at a familiar multiplayer problem: wallhacks.
In posts from the official Call of Duty account, the company said the system changes what information the server sends to a player in the first place. Specifically, Activision said that when a player should not be able to know an opponent’s position, “the server can now withhold that opponent’s location data from their hardware”. The company presented that as a way to make cheat tools less useful because they cannot reveal information they never receive.
That is the core pitch behind Server Culling. Activision framed it as another layer in its anti-cheat efforts rather than a complete fix on its own, saying it will work “alongside the rest of our anti-cheat systems”.
Where Activision says it will apply
According to Activision, Server Culling will cover every map available at launch for Modern Warfare 4. In the same post, the company said that includes DMZ and Combat Outpost, and that it will also extend to new live season maps for multiplayer, DMZ, and Warzone starting in Season 1 and beyond.
CharlieIntel summarized Activision’s announcement by describing Server Culling as a new Ricochet Anti-Cheat feature for Modern Warfare 4 and Warzone. CharlieIntel also said the feature changes how server data is sent back for player locations to help prevent wallhacks from working.
For now, the main qualifier is that the available details come from Activision’s own announcement posts and CharlieIntel’s summary of them. In the supplied evidence, Activision explained what Server Culling is supposed to do and where it plans to use it, but it did not provide live-match performance data showing how effective the feature is. The immediate takeaway is narrower: Activision is trying to make wallhacks harder to use by denying cheat software some of the location data it would otherwise exploit.
