Call of Duty now has a guide on how to enable its convoluted security features so you can play the Modern Warfare 4 beta on PC

As the Call of Duty: Modern Warfare 4 beta approaches its first weekend, Activision's Ricochet anti-cheat team has released a comprehensive guide for PC players to enable essential security features. Familiarity with TPM 2.0 and Secure Boot requirements on Windows is likely, given the prevalence of such restrictions in multiplayer games over the past five years. These measures have been tightened for Modern Warfare 4 compared to previous titles like Black Ops 7 and the current Warzone version.

Previously, players failing to meet the requirements were restricted from accessing specific game modes, including Ranked Play, and could be placed in separate matchmaking pools with other non-compliant players. With the Modern Warfare 4 beta, the rules have become even stricter, now prohibiting players from playing any online game mode if they don't meet the requirements.

In response to these changes, Activision has provided an extensive guide and video tutorial, walking users through the process of enabling the necessary security features. The tutorial covers UEFI/BIOS settings for both AMD and Intel systems, as well as the use of the Call of Duty Secure Attestation Wizard, an app to test whether the PC meets the security requirements. The app was updated earlier this month to accommodate Modern Warfare 4.

Secure Boot and TPM 2.0 are low-level system features that provide anti-cheat software deeper access to the Windows operating system. By loading during the PC's startup phase, these features prevent cheats from running during startup. Both have become increasingly necessary in competitive games on PC, such as Battlefield 6, Valorant, and other major titles.

Battlefield 6 already enforces Secure Boot requirements, and Battlefield Studios plans to implement TPM 2.0 soon. According to Battlefield Studios' technical director, Christian Buhl, these low-level systems are crucial in the ongoing battle against cheaters, even though they may restrict some players from participating in the game.
