In this guide, you’ll find the exact locations of all secrets, gold, toys, and codex entries hidden throughout Chapter 12 – Sentinel Command Station in the game Doom: The Dark Ages.
13 Gold (13/177) + Secret 1 + Codex (Sentinel Command Station)
Go into the ventilation shaft, then turn right, left, and right again. Drop down, then turn right two more times to find 8 Gold.
From the last collectible, turn around and walk straight ahead to exit the shaft. At the end, you’ll see a broken part of the wall. Go inside to find 5 more Gold and Codex.
Secret 2 + 22 Gold (35/177) + Weapon Skin
Go to the Control Room, shown on the map below. On the left side, there’s a breakable wall. Go inside to find Gold scattered on the ground.
In that same room, look to the left near the door to find a weapon skin.
Then, walk to the end of the room and look to the right. You’ll find 8 Gold hidden behind a vehicle.
8 Gold (43/177) + 6 Gold (49/177) + Secret 3
After the first red combat fight, go into the next room and interact with the console. This will open a path in the hallway that leads to the room beside you. Inside, you’ll find 8 Gold on both sides of another console.
Next, use the second console to open a ventilation shaft. Climb inside it to find 6 Gold, then turn right again to reach the Life Sigil and unlock the secret.
Demonic Essence – Health
This is automatically available by defeating the Pinky Rider miniboss.
50 Gold (99/177)
Keep going through the area until you reach a room where you need to open a door. The chest with 50 Gold will be on the right side.
Secret 4 + Ruby + 8 Gold (107/177)
Keep going through the chapter and take the elevator down. Defeat the enemy across the gap and then cross over.
Follow the hallway and drop into the hole. You’ll find a Ruby there. Look behind the big cube to find some Gold.
12 Gold (119/177) + Yellow Key + Secret 5 & 50 Gold (169/177) + 8 Gold (177/177) + Secret 6 + Secret 7 & Secret Key + Secret Key Door 1 + Secret 8 & Wraithstone
Keep going through the chapter until you reach a room with the Yellow Key. You’ll see Gold lying on the floor—pick it up.
Take the Yellow Key from the body (this is part of the story), then open the gate. Jump across the gap to find a chest with 50 Gold.
Now, turn around and you’ll see a breakable cover on a ventilation shaft. Break it and go inside.
Take the first left to find 8 Gold.
Keep moving through the shaft and turn left again. You’ll see a wall you can climb—don’t leave the shaft yet. Turn around to find a Life Sigil and a secret hidden behind it.
Now, exit the shaft and defeat all the demons in the room. This will unlock the Secret Key.
Pick up the key and go to the left to open the Secret Key gate. Inside, go near the stone with the Wraithstone. A monster will appear—defeat it, then collect the Wraithstone.
Secret Key Door 2 + Secret 9 + Toy (Kreed Maykr)
After the final red combat fight, go into the side room on the left. Open the Secret Key gate to find a toy inside.
