Surviving Little Nightmares 3’s Institute: A Complete Guide to Chapter 4

When I first stepped into Chapter 4 of Little Nightmares 3 back in 2025, I thought I was ready. The Institute had been looming over Low and Alone for the entire game, and finally reaching it felt like crossing into a waking nightmare. Now, a year later, I still consider this finale one of the most harrowing and rewarding sequences in horror gaming. If you’re diving into the Spiral’s last stretch, I’ve got your back. This guide walks you through every collectible, every deadly encounter, and that unforgettable final boss fight.

Right from the opening scene, Chapter 4 throws you onto a gloomy shoreline. Before you head into the building, check the far left near the camera. Move past the large staircase and shine your flashlight into a small space to its right. There you’ll find the first ghost, silently drawing a face in the sand. It’s a quiet, deeply unnerving moment that sets the tone for everything that follows.

Once inside, I made my way past the party hats room into a long hallway. Hugging the camera side, I reached a dead end with a barricaded door on the right and some pushable doors on the left. Pushing through those left doors reveals a tiny office where the first collectible doll sits in the middle of the floor. After that, I returned to pull the plank off the other door and pressed onward.

Soon you’ll run into a carnivorous plant that won’t let you pass while it’s alive. I learned the hard way that Low needs to shoot it when it opens its jaws. If you’re playing as Alone, you can call Low to do the job. A little patience goes a long way here.
