To run no body armor in Ready or Not , go to your loadout and select no armor for the vest and no helmet if you want a full no-armor run. A community guide and player posts note that some armor customization options disappear when you pick no armor, which is expected behavior.

How to set it up

  1. Open your loadout in the SWAT unit room.
  2. Set your armor to no armor.
  3. Set your helmet to no helmet if the challenge you’re doing requires it.
  4. Pick your weapon and start the mission.

What to expect

  • You will have less protection, so positioning and room clearing matter more.
  • Some runs or trophies only require you to finish the mission without armor, not get a perfect score.
  • Players also report doing full challenge runs with no armor, no helmet, and even no primary weapon for extra difficulty.

Small note

One armor guide explains that in Ready or Not , armor coverage and material choices matter, but selecting no armor basically removes that protection entirely. That makes it a valid but much riskier style of play.

TL;DR: open loadout, choose no armor , optionally choose no helmet , then run the mission carefully.
