To unlock the secret bunker in Reanimal, you need to find the bunker code. The game hides the bunker code in chapter 1, but it will be of no use till you reach chapter 6. You will need to remember the hidden pattern and then enter it correctly later in the story. In this guide, we will show you how to find the secret bunker and input the secret code.
How To Find a Secret Bunker

Go back to Chapter 1: Dead in the Water. After you finish the boiler puzzle at the Mill, you will go outside and on the right side, you will see two doors. Go through this area to find a catwalk that goes towards the office.
Near the cardboard boxes on the right side of the room, you will find a pattern made up of dots. The dot pattern is the hidden code that you need for the secret bunker.
How To Input The Secret Code

You will find the Secret Bunker at the start of Chapter 6: Nobody Left Behind. After the car crash, your character will crawl out and move through the tunnels till they reach an old bunker. Inside, there is a control panel with buttons and a switch. To restore the power, go to the door on the right side of the bunker.
Outside, you will see a generator. Interact with it to start it. Once it is running, the lights inside the bunker will turn on. Now, go back inside the bunker, and you will be able to use binoculars to look towards Cannon Island.

Here, you will find a pattern of dots. Enter the code by pressing the buttons, so the light matches this order: Bottom, Middle, Top, Bottom. Press the buttons, and this will call in a crate of cannon Shells.
Next, enter the hidden code you found in Chapter 2. The correct order is: Middle, Bottom, Bottom, Middle. Putting in this code unlocks the secret bunker achievement. You will also receive a secret poster from the machine.
