Doom The Dark Ages Chapter 12 takes place on the Sentinel Command Station. This military installation is one of the more linear levels in the game, as the Slayer defends its command rooms and corridors from a demon invasion. Besides the main objective, there are a series of secrets that can be found in this chapter. With this in mind, we’ve created a guide highlighting all the Secret locations on the Sentinel Command Station in Doom The Dark Ages.
Doom The Dark Ages Chapter 12 Secret Locations
There are a total of nine secret areas in Doom The Dark Ages Chapter 12. You can find gold pick-ups, a Collectible Toy, and even a Wraithstone in these locations. Check out all the locations down below:
Secret Area 1

Follow the on-screen main objective indicator until you pass the exploding vent. Now, head towards and look for a damaged wall on the right-hand side. Look inside it to grab a Codex Entry.
Secret Area 2
Keep pushing towards the main objective until you jump down into the central command room, which is littered with friendly NPCs. Look left while facing the central console, and you’ll find a breakable wall. Use your shield to break it, and you’ll find a Weapon Skin inside.
Secret Area 3
While following the beaten path, you’ll eventually end up in an expansive hall, at the end of which sits a locked door that requires a yellow keycard. Once you’re here, look at a caved-in wall on the left-hand side, which links this area to a different corridor.
Here, you’ll find a locked gate that can be opened using the Secret Key. To find its location, be sure to check out our guide. As for this hidden location, you’ll find the Kreed Makyr Collectible Toy sitting inside.
Secret Area 4
Follow the on-screen indicators until you get to the nearby Sentinel Shrine. Stand outside the metal gate that leads towards it, and look to your left. You’ll be able to spot a climbable wall. Scale it and turn right to discover the fourth location.
Secret Area 5
After taking the elevator to the upper floor, follow the on-screen indicator until you collect the yellow keycard. Open the metal gate that sits in the same room using the keycard. You’ll now see a straight jump leading to a lower floor. And above it, you can spot a tiny cubby with a gold cache sitting inside. Jump to it to discover this location.
Secret Area 6
After collecting the gold cache, make a 180-degree turn, and you’ll spot a breakable wall. Shield bash your way through it, explore the adjoining vent thoroughly, and you’ll find a climbable wall that leads to another breakable barrier. Before you smash through it, simply turn around to find a cheekily hidden Life Sigil.
Secret Area 7
After collecting the sigil, you can break the barrier in front. On arrival, you’ll be greeted by a horde of demons, so be prepared.
Secret Area 8
After exiting the last hidden location, you’ll spot another metal gate almost directly in front of you. This one also requires a Secret Key, so interact with it to unlock it. Inside, you’ll find a Wraithstone in this secret location.
Secret Area 9
Exit the location using the same gate, turn left, and then make a right in the adjoining corridor. There’s a hole in the ground you can jump through, and inside you’ll find a Ruby.
That wraps up our guide on all the secret locations in Doom The Dark Ages Chapter 12. If you’re struggling to find any of these locations, be sure to let us know in the comments.
