To play the new shooter on a PC, TPM 2.0 and Secure Boot are required. An official tool is available to help with setup.
Shortly beforethe first beta weekend for Call of Duty: Modern Warfare 4, Activision’s Ricochet anti-cheat team has spoken out. The developers havepublished a detailed guide. This guide helps PC players enable certain security features. These features are absolutely necessary if you want to play online.
Have you played multiplayer games on PC over the past five years—especially shooters? Then you’re surely already familiar with Windows requirements like TPM 2.0 and Secure Boot. These requirements have been part of Call of Duty for a few years now. But for Modern Warfare 4, Activision is apparently tightening the screws even further. The requirements are stricter than they were in Black Ops 7 or the current version of Warzone.
Stricter consequences for missing security features
Previously, the rule was: Players who did not meet the requirements were simply barred from “accessing certain game modes (including Ranked Play) and playlists.” Activision also warned that matchmaking “may place such players in separate lobbies with other players who also do not meet these requirements.”
For the Modern Warfare 4 beta, the developers are now drastically tightening these rules. The statement is now unequivocal: “Players who do not meet the requirements will not be able to play a single online game mode.”
Video walkthrough and official testing tool for PC players
The guide comes at exactly the right time and is extremely helpful. After all, you absolutely need these features just to launch Modern Warfare 4. The developers are even going a step further. They’ve released a complete video that walks you through the process step by step. In it, they show you detailed UEFI and BIOS walkthroughs for AMD and Intel systems.
This tutorial is truly worth its weight in gold. Especially when it comes to understanding how the different platforms actually refer to TPM. Even more practical is theCall of Duty Secure Attestation Wizard. You can download this app to your PC. It automatically checks whether your computer meets the strict security requirements. Activision updated this little tool just earlier this month, right in time for Modern Warfare 4.
Technical Background and a Growing Industry Trend
Secure Boot is a fundamental system feature. It grants the anti-cheat software deeper access to your Windows installation. The anti-cheat program loads directly during the PC’s startup phase. This effectively prevents cheats from activating as soon as the system boots up. TPM 2.0 builds directly on Secure Boot. It provides you with an additional, hardware-based layer of protection. The system immediately detects if anyone has tampered with the PC’s boot process.
In recent years, more and more competitive PC games have required these two features. These include Battlefield 6, Valorant, and several other major titles. In the case of Battlefield 6, the Secure Boot requirement is already strictly enforced. In addition, Battlefield Studios plans to make TPM 2.0 mandatory soon as well.
TPM 2.0 Compliance Warning Now Live
As mentioned in our Season 3 Anti-Cheat update, we’re now rolling out an in-game warning for players whose systems aren’t compliant with our TPM 2.0 requirements ahead of Season 4.
At this stage, this is only a guidance note, and players…
