Does Modern Warfare 4 have anti-cheat?

Yes — it uses the RICOCHET Anti-Cheat system, which runs as a kernel-level driver on PC.

This anti cheat discussion is a starting point for understanding the terminology used in the linked RICOCHET guide. Read the short answer together with that guide rather than treating a single sentence as a current compatibility report. A description of a security system does not establish whether a particular third-party product works with the game version installed on your PC.

Separate three questions when reviewing a product: what features it lists, what delivery requirements it has, and what account risks remain. An overlay setting describes what appears on a display or recording. A delivery method describes how a service is provided. Neither description, by itself, establishes protection from enforcement or confirms a live product status.

When asking an anti cheat question, include the game version, launcher, Windows version, and the date of the information you are comparing. Quote the specific statement you want clarified and link to its page. Keep account credentials and private purchase details out of public discussions. A clear question makes it easier to distinguish an outdated description from a requirement that still needs confirmation.

Use the source guide for related terminology, then contact support if you need clarification about a listed package. Recheck compatibility after game or operating-system updates. Earlier screenshots, older discussions, and a previously working configuration should not be treated as confirmation for a newer build. This page provides reading context and does not publish a live detection-status feed.
