Activision has finally announced its upcoming anti-cheat initiative designed specifically for Call of Duty. Named RICOCHET, it is a "multi-faceted approach to combat cheating, featuring new server-side tools which monitor analytics to identify cheating, enhanced investigation processes to stamp out cheaters, updates to strengthen account security, and more". Along with the improvements is the launch of a new PC kernel-driver, which monitors and reports applications that attempt to interact with the game.
Essentially, a kernel-level driver is a computer code that operates with high privileges on computers as it has access to all resources on the system while it's running. The driver will assist in identifying cheaters and strengthening the overall server security.
According to Activision, the anti-cheat system will enhance security for both Call of Duty: Vanguard and Call of Duty: Warzone when it launches later this year alongside the Pacific update for Warzone. It will be available first on Warzone and arrive for Vanguard at a later date.
