1. Introduction

Far Cry 5 is an open-world first-person shooter designed primarily for single-player and cooperative gameplay. In the context of game security, the design philosophy differs significantly from competitive shooters. The developers opted for a "trust-the-client" model to ensure smooth synchronization in co-op mode, rather than implementing strict server-side validation.
