In this guide, you’ll find the exact locations of all secrets, gold, toys, and codex entries hidden throughout Chapter 7 – Siege Part 2 in the game Doom: The Dark Ages.
Secret 1 & 2 + 53 Gold (53/183)
Keep going through the chapter until you reach a turret. Use it to defeat the Titan. After that, leave the room and push the crate to move forward.
Once the crate is pushed forward, look to the left and you’ll see a breakable wall. Smash the wall to find your first secret, 3 gold coins, and a Life Sigil.
Now, leave the room again and climb up the crate you pushed earlier. Keep climbing the walls to reach the top. At the top, you’ll find another secret and a gold chest.
Secret 3 + Collectible Toy 1 (Pinky Rider) + 26 Gold (79/183)
Go to the next area shown in the image. Look to the right for a wall you can climb and go up.
After climbing, turn right and throw your shield up to drop another climbable wall.
Climb that wall too, then look to your left. You’ll see a breakable wall across the gap. Jump over, break it, and go inside.
Inside, look to the left side of the room for another wall to climb. At the top, you’ll find 8 gold coins. Keep going up the ramp to find a toy at the end.
Now go back to where you jumped across the gap. You’ll also find a few more coins on the scaffolding nearby. Also, go through the doorway on the right for more gold.
Secret 4
Keep playing through the chapter until you reach the spot marked on the map. Go to the left side and head to the end of the room. In a small corner, you’ll see a blue breakable wall. Smash it and go inside to find a secret.
Secret 5 + Purple Key + Secret 6 + Ruby 1 + Secret 7 + Codex 1 + 46 Gold (125/183)
Keep playing until you reach the place shown on the map.
From the upper floor, go to the left and look for a breakable wall on the right. Break it to find a secret.
Go into the next room and collect gold on the right side. Then, grab more gold on the left side of the room.
Exit through the broken wall and use the jump pad to get across to the other side of the balcony. Pick up the purple key.
Go inside and collect 3 gold on the left. Then drop down to get 4 more gold.
Next, go left and stay close to the right wall to find 16 gold.
After beating the monster that appears, keep staying close to the right wall. Look to your right to find a purple gate. Open it to find the next secret and a ruby.
Leave the room and keep following the right wall until you find another purple gate.
Go inside and follow the path to find 8 more gold and a Codex page at the end.
Secret 8 + Ruby 2 + 8 Gold (133/183)
Keep playing the story until you reach a big open area with a crashed UFO and the goal that says “Rescue Novik.”
After you defeat all the demons, go to the right side of the area and climb the crates. Follow the path to find a secret and a ruby.
Now follow the main goal and enter the crashed UFO. After you drop down, look to the left for a hidden path. Jump over to find 8 gold coins.
Secret 9 + 50 Gold (183/183)
Leave the UFO to reach a new area shown on the map below.
Climb up the crate and go left. Throw your shield at the chain—this will make the big fan outside start spinning.

Then go back outside and look behind the crate to find a gold chest.
