Doom: The Dark Ages is here. The latest shooter in the Doom franchise from iD has a bit of a different feel with its more open world style of levels. Within each level is many different secrets on the form of collectibles, upgrades and other items. This guide will help you with finding all the upgrades and collectibles in the final chapter, Chapter 22: Reckoning.
Codex – Marok
As soon as the chapter starts and you drop down a level look to the right where you will find the codex. This should be your last codex and unlock the Lore Nerd achievement/trophy.

Ruby #1
Complete the big battle in the first area and proceed as normal. Climb the wall and solve the little puzzle. When you enter the next room before taking a right towards the objective look to a little room to the left. The floor will be missing and a launcher will be below.


Launch yourself up, there’s gold behind a breakable wall here and then follow the path to the other side. Drop down into a hidden room with the Ruby inside.

Ruby #2
You will get to a section where you need to stand on a green button to progress the chapter. Just before the button will be a breakable wall. In behind that wall will be a gear to put your shield saw into. This will raise a climbable wall to your right.


Climb up the wall then follow this hallway around and jump the gap when you get to it. At the end will be another gear that you will need to put the shield saw in and then climb up again. After climbing recall your shield and turn around and climb yet another wall where you will then find the Ruby.

Purple Key
This is part of the story so you can’t miss it but we are highlighting it because now you need to do a whole lot of backtracking to grab everything you’ve missed without the purple key. After obtaining it head through the purple gate and let’s get backtracking.
Ruby #3
Drop down after going through the gate and head all the way back to basically the beginning of the mission. On the now left hand side at the end will be a room to unlock. Inside will be the final Ruby.

Collectible Toy – The Old One
Turn around and head back out staying to the right hand side. You will come to a room on the right and inside will be a purple gate you can now unlock. Move forward into the large room and break the nest to trigger a large battle. At the end here if you have BFC ammo left will be where you can complete the challenge.
Once the battle is done look in the back of this area for the toy.

Collectible Toy – Ahzrak
Now return back to the first big room but just before you do look to your left. You will see a life sigil behind a broken wall. Infront of that wall though is a hole you can drop down into.

At the end of this underground area is the toy. This should be your last toy and unlock the toy collector achievement/trophy for you.

Demonic Essence – Ammo
Proceed past the next shrine and drop down as the game wants you to. Defeat the massive wave of enemies and at the end you will obtain the upgrade. If you’ve been following along this should be your final ammo upgrade and unlock you the Essential Ammo achievement/trophy.
This will also be the final thing you need to collect in the game! You should now be well on your way to that Doom: The Dark Ages completion!
