The Unseen Monsters mod removes the highlighted circles from the monsters, so that they are not visible to Geralt, but can still be heard.

It's compatible with the latest patch for The Witcher 3: Wild Hunt.

Installation:

Download and extract the archive into the "...\The Witcher 3\Mods\ " folder.

After installation, the folder structure should look like this: "...\The Witcher 3\Mods\modUnseenMonsters\content\... "

Supports installation with NMM.

The idea for this mod came from arnold12345. He noticed that when you hear a monster, you can see its outline. But when you don't see it, you can't hear it. So he decided to create a mod that removes the highlighted circles from the monsters.
