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 Chapter 12: Sentinel Command Station.
Codex – Sentinel Command Station
Progress through the first vent section and drop down, progressing through the second. Once it opens back up instead of going left head straight and then look to your right to find some gold and the codex.


Weapon Skin
Progress until you drop down a second time into what looks like the command area. Walk forward and go down the stairs. To the left will be a breakable wall, do so and head through. At the end of the area will be the weapon skin.


Demonic Essence – Health
Progress into the chapter past the point of receiving a new gun. In the room beyond the new gun there will be a massive horde of enemies. The last one will find the upgrade.

Ruby
Progress up the elevator and across the shield recall jump. Once you land on the other side of the jump go directly straight and drop down a hole in the floor to find the Ruby.


Purple Key
After obtaining the yellow keycard go forward and unlock the gate. Instead of dropping all the way down jump across to the hole in the wall with the gold. From there turn around and shield charge through the breakable wall into the vents. Follow the path up into the room with the key. Defeat the enemies and claim the key.


Wraithstone
With the purple key now in hand run pretty much straight across the hall to unlock the other purple door. Defeat the enemy inside and grab the stone.

Collectible Toy – Kreed Maykr
Drop all the way back down now and into the big room to face yet another wave of enemies. Once they are cleared head back to a room you previously visited where the toy was (should be easily visible on your map by now. Using the purple key open the gate and grab the toy.

This should be your last collectible needed for the chapter. See you in chapter 13!
