Secrets and Collectibles in DOOM: The Dark Ages’ Sentinel Command Station
Your journey through the Sentinel Command Station will lead you to uncover numerous hidden treasures. Keep an eye on your in-game map for the following collectibles:
- 9 Secrets
- 1 Codex Entry
- 1 Toy Collectible
- 1 Weapon Skin
- 1 Demonic Essence Upgrade (Health)
- 1 Ruby
- 1 Wraithstone
As reiterated throughout our walkthrough, regularly check your map. Collectibles and secrets will be marked, and you can use the right-hand list to monitor what you have gathered and what remains to be found. A wise strategy is to thoroughly explore each area before advancing to new zones or crossing points of no return.
Collectible #1 and Secret #1
Commence your quest by entering the opening room where you will encounter two doors, each housing a terminal. Interact with both terminals and await the vent on your left to be blown open.

Following the vent’s unveiling, make your way through and veer right upon exit. This will lead you to a secret area where you can find some Gold along with a Codex entry, marking your first secret discovery in the chapter.
Collectible #2 and Secret #2
Proceed according to your quest marker through the point of no return. In the subsequent chamber, a Weapon Skin can be glimpsed behind a locked gate to your left. Approach the hologram of the Command Station and find a vent to Shield Bash through just next to it.

Journey through the vent to loot more Gold and unveil your second secret—a Weapon Skin awaits you.
Secret #3
Continue following the quest marker past another irretrievable area and confront an enemy mob. Your focus now is to secure the Yellow Keycard and access the Hangar.
Head through the gap in the wall to your right. Within the next room, you’ll find a locked gate needing the Secret Key, but first, let’s climb up the right corridor wall leading to a temporarily sealed vent. After scaling the wall, engage the terminal behind you.

Post-terminal interaction, return to engage the enemies. Once dealt with, progress right, where you will discover a Sentinel Shrine, additional Gold, and interactable terminal that opens the previously mentioned vent. Dive inside to secure your third secret area along with a Life Sigil.
Demonic Essence Health Upgrade
Continue on by defeating a Pinky Rider in the next area to snag a Demonic Essence Health Upgrade.
Secret #4
When you reach a room featuring a conspicuous Gold Chest, take note of the required terminal on the left-hand side. Proceed through the illuminated green door into the elevator following your quest marker.
Upon emerging at the top, navigate toward the Yellow Keycard’s location, keeping an eye out for a Mancubus on a distant ledge. Utilize the nearby Flesh Node to jump across to him.

While your objective prompts a right turn, continue straight to leap onto a statue that cradles a Ruby, marking your fourth secret.

Shield Bash a crate here to forge an upward passage, then resume your quest.
Secret #5
Encounters with Enforcer Pinkies resume in the next corridor, alongside another locked gate waiting for the Secret Key. Fear not, for we will obtain it soon. Enter the forward room to procure the Yellow Keycard.
Using this card, you can unlock the gate ahead and discover an alcove containing a Gold Chest, which signifies the fifth secret area.

Afterward, revisit the Gold Chest location to shield into the newly accessible vent.
Secret #6, Secret #7, and Obtaining the Secret Key
From the alcove of the Gold Chest, reverse your path, spotting the vent you can now access with a Shield Bash.

Navigate through the vent and once you ascend, execute a U-turn to leap over to a Life Sigil, unlocking the sixth secret.

In the next area, the Secret Key awaits at the room’s center, marking your seventh secret once you clear the adjoining combat.
Secret #8
Post-key retrieval, exit into a corridor that reveals a locked gate leading to Wraithstone; use the Secret Key to unlock this area, leading you to your eighth secret amid an encounter with an Agaddon Hunter.
Return once more to the Gold Chest, this time following your quest through the elevator shaft.
Secret #9 and Collectible #3
Within the next chamber, grasp the Shield Rune: Auto Turret from a luminous green pool, then tackle the ensuing enemies. Before you use the Yellow Keycard for the Hangar, explore the gap in the wall (navigational path illustrated below).

In this familiar corridor, access a previously locked gate containing the Collectible Toy, Kreed Maykr, completing this chapter’s search for secrets.
Stay tuned for the upcoming Chapter 13!
