Little Nightmares 2 guide: Signal Tower door puzzle

At the end of Little Nightmares 2, you’ll find yourself in the Signal Tower, trying to navigate through a series of hallways lined with purple-pink portal doors. They work like a Scooby-Doo hallway, with doors on the left exiting on the right and vice versa. They’re confusing to navigate until you learn the tricks.

In this Little Nightmares 2 guide, we’ll walk you through the Signal Tower door puzzle.

First hallway (two doors)

After the first set of stairs, you’ll reach a hallway with two doors. The two open doors are in the lower right and upper left.

The trick to this hallway is to listen to the music — it’s louder when you're standing by the door you should walk through.

Go through the doors in this order:

1. Lower right
2. Lower right
3. Upper left
4. Upper left

Right-to-left hallway

This will take you with a hallway that runs from right to left.

Listen for the music again to find the correct door.

1. Skip the first open door.
2. Go into the middle, rolled-up-halfway door.

This time, you should also notice white sparkles coming off of Mono. That’s your clue for the next area.

Second hallway (one door)

This one is kind of a gimme. Step away from the door’s light, and then head back through the same door.

This will lead you to a new stairway.

Third hallway (four doors)

In the third hallway, there are four doors with two on each side. When you first enter, two of the doors will be closed.

The key this time is to look for those white sparkles to come off of Mono when he’s standing in the light from a doorway. The music will also be louder in the correct doorway.

The sequence this time is:

1. Push open the lower left door, but don’t go through (you’ll need it open in a second)
2. Upper left
3. Upper right
4. Lower right

This will take you to another set of stairs.

Fourth hallway (seven doors)

The next hallway is the most complicated yet. As soon as you arrive, push over the plank to create a bridge to the back half of the hall.

Again, you’ll looking for those white sparkles and loud music when you stand in the light from a doorway.

The sequence is:

1. Bottom right
2. Second from bottom left
3. Second from top left

That will take you to the next stairway.
