Call of Duty: Modern Warfare 4 Introduces Server Culling to Attack Wallhacks Before They Reach the Player's PC

Activision and Infinity Ward have detailed another piece of Call of Duty: Modern Warfare 4's anti-cheat technology ahead of its October 23 launch. Server Culling is designed to attack wallhacks at the source rather than merely attempting to detect cheating software after the fact. In simple terms, the game server decides what information a player legitimately needs to receive. If an enemy is completely hidden and irrelevant to what should currently be visible, the server can withhold that enemy's positional information from the player's machine. A wallhack cannot conveniently reveal data the computer never received. This is not an entirely new concept in competitive multiplayer networking, but deploying it across every Modern Warfare 4 launch map is significant given Call of Duty's enormous audience and equally enormous attractiveness to cheat developers. There are technical trade-offs: culling has to predict visibility quickly enough that legitimate players do not suddenly materialise a fraction of a second late when entering view. Activision says its implementation has been designed around those problems. Anti-cheat remains an arms race rather than a problem anybody permanently solves, but server-authoritative approaches are promising because they reduce the amount of useful hidden information sitting on a potential cheater's PC. The best wallhack, it turns out, may be giving the wall nothing interesting to hide.
