Unlike standard shooters, Ready or Not emphasizes non-lethal force and strict Rules of Engagement (RoE). Players are graded on their ability to secure suspects through compliance rather than immediate lethal force.
The latest major expansion focuses on a terrorist organization called the Mariposa Lily Organization. It introduced three new missions (such as an active shooter situation at Blackwood Pier), new weapons like the G18-C automatic pistol and RTWC-6.5 battle rifle , and enhanced suspect AI.
The game expanded to PS5 and Xbox Series X/S, including cross-play support. Previous Expansions:
