To get S rank in Ready or Not, the safe rule is: finish the mission with no casualties , arrest suspects alive, complete every objective, and secure all evidence. Non-lethal gear is the easiest way to do it, and time usually does not matter.

What matters most

  • Use non-lethal weapons like the beanbag shotgun, pepperball gun, taser, CS gas, or other less-lethal options.
  • Do not kill suspects or civilians, and do not let teammates cause lethal downs either.
  • Secure all required evidence and dropped weapons, including soft objectives on the map.
  • Keep your squad alive and avoid friendly-fire or misuse-of-force penalties.

Loadout tips

  • Give every AI teammate non-lethal primary weapons so they do not switch to lethal sidearms.
  • Remove lethal handgun ammo from squad loadouts if needed.
  • Bring a gas mask if you use CS gas.
  • A shield, mirror wand, and slow, methodical clearing help a lot on harder maps.

Practical approach

  1. Clear rooms slowly and use commands to force surrenders.
  1. Arrest everyone instead of “finishing” enemies who go down.
  1. After the last suspect is handled, issue Search and Secure to mop up evidence and dropped weapons.
  1. Double-check every room for missed objectives before ending the mission.

Common mistakes

  • Headshots with beanbags can still be lethal.
  • Leaving a dropped weapon unsecure can cost the rank.
  • Letting a teammate carry live ammo can ruin an otherwise clean run.

S rank is basically a perfect non-lethal run: everyone alive, everything secured, and every objective done.
