Henry's Rock: The Red Button & Hidden Secrets

How to complete the achievements The Red Button & Hidden Secrets

Introduction

This is a guide on how to complete the achievements The Red Button and Hidden Secrets, and it also serves as my first guide ever.

The Red Button

First I'm going to go over The Red Button. This achievement can only be achieved on the Overkill or higher difficulty. First go through the heist like normal until you get to the computer which will tell you where the first box is located. To the right of the computer there is a red button that has a glass/plastic cover on it.

Take off the cover then press the button. DO THIS BEFORE INTERACTING WITH THE MAINFRAME. This will activate two ceiling turrets and it will cause gas to cover the area surrounding the loading dock, you will be safe on the platform but you still could be in the line of fire from the turrets.

Turret pods before they are activated.

One of the turrets after the button is pushed.

The other turret after the button is pushed.

The toxic gas that fills most of the room after the button is pushed.

You will be safe from the toxic gas while on the metal platform and to be safe from the turrets you can hide under the metal roofing of the control hut.
After pressing the button what I did was I destroyed the turrets, but this might not be needed to complete the achievement, I simply did it just to make the heist easier. After the gas has cleared you can proceed to complete the heist like normal. Once you get both the boxes, secured them, and escaped you should earn the achievement.

Hidden Secrets

Now I'll explain the Hidden Secrets achievement. This achievement ISN'T difficulty specific. First start doing the quest like normal all the way until the first box location is revealed. If Locke tells you the first box is in the archeology room then you're in the clear. IF the box isn't in the archeology room the first time, continue like normal until the second room is revealed.


(Archeology Room)

IF the second room isn't the archeology room either restart until it is or complete the heist and try again. If the first or second room is the archeology room continue like you normally would in that room. Once the drill is done and you've found all the correct symbols to open the golden crate, pick up the box inside.


Then located on the sides of the golden crate are three symbols- a rhombus, a ouroboros, and a pyramid.

You must interact with these in the correct order which is the pyramid first


then the ouroboros


and then the rhombus.


This will active the achievement and the secret will reveal which I'm not gonna show so I don't spoil what the secret is. You don't need to finish the heist for this achievement.

Conclusion

Again this is my first guide and I should have all screenshots needed to explain how to do it. I hope this guide was helpful and explains it well. Thanks for reading. :D

If kento is in the end doesnt that mean he is watching? He is watching what is happening to those boxes. Could Kento be part for the Kataru? Is he a traitor?
