After entering the Trident Fort, reach the door without being seen.
The Trident Fort is Ganesh’s ruin in the southeast part of the map in chapter 4, above the waterfalls. Once you’re inside and you can see the rebels patrolling the area, we recommend sticking to the left – there’s more cover that side and less enemies.
All you have to do is reach the door at the back of the area without being detected to unlock this trophy.
Quiet as a Mouse
