To get an A rank in Ready or Not , you generally need to finish the mission cleanly: complete the main objectives, secure evidence, and avoid major penalties like civilian or suspect deaths, friendly fire, or failed objectives. In practice, A rank is usually a strong but not perfect run ; an S rank is the “near-flawless” version that typically requires non- lethal arrests and every objective/evidence item completed with no deaths.

What usually helps

  • Complete every primary objective.
  • Clear any optional/hidden objectives if they appear.
  • Secure all evidence and dropped weapons.
  • Keep civilians and suspects alive when possible.
  • Avoid team damage and unnecessary force.

Why people miss S but still get A

A lot of players think they did everything right but still miss S because someone died, an arrest wasn’t completed, or an objective item was left behind. That’s why runs that are very good, but not perfectly non-lethal and fully complete, often land in the A or A+ range instead of S.

Practical tip

If you want to push from A to S , use non-lethal tools, slow down, and double-check the tablet/objectives before extracting. Time usually matters less than completeness and no-fatality play.
