Utilizing the map is crucial in DOOM: The Dark Ages. Regularly checking it after defeating enemies or completing objectives will help reveal secrets nearby. The right side of the screen offers a checklist of collectibles gathered and those still awaiting discovery. Always examine the map before proceeding past any critical areas, as some regions may restrict your return.
Secret #1
After dispatching your first enemy in this chapter, you’ll gain access to a Rocket Launcher via an Arsenal drop. Before advancing, head left towards a Flesh Node you can Shield Throw. This will enable you to reach platforms holding Gold Bars and a Life Sigil—this marks our first secret location.
Following this, continue into the corridor past the Arsenal drop and beyond the point of no return.
Secret #2 and Collectible #1
Your next objective is to destroy two Hell Cannons, while also facing five different enemy encounters marked on your map.
Upon exiting the previous corridor, head to the right towards the Sentinel Shrine indicated on the map.
Pass the trap-elevator near the Shrine, taking care of any remaining enemies. Outside, follow the trail of Gold leading to our first collectible: a Codex entry.
Return past the Shrine and follow the rest of the Gold trail in this outdoor area to unlock a gate leading back to the level’s start. Before wandering off, return to the trap-elevator and step onto it.
Once at the top, you’ll jump outside to find the second secret area and collect a Ruby.
Demonic Essence Upgrade (Armor)
From the Ruby’s location, drop down and navigate right to encounter your first wave of enemies. Upon defeating the Leader Mancubus, you will obtain the Demonic Essence Armor Upgrade for this chapter. Don’t forget to explore the building behind the Mancubus and destroy the Hell Cannon located inside before progressing.
Collectible #2
Next, you can secure the second collectible—a Weapon Skin. Ascend the stairs on the northeast side of the building holding the Hell Cannon.
The route to the Weapon Skin is illustrated in the map below.
Secret #3 and Demonic Essence Upgrade (Ammo)
Next, open your map, which will showcase another small enemy encounter near your present location.
To initiate this encounter, you must Shield Bash the large tree marked with a green sigil, located near a Hell Portal. After defeating the Revenant here, you will unlock the Demonic Essence Ammo Upgrade for this chapter.
Secret #4 and Secret Key
Next, navigate back to the area where you gathered the Weapon Skin. Drop off the ledge and head left to collect several Gold Bars amidst some aggressive tentacle enemies. Shield Bash through the exit to return to the beginning of the level.
This time, rightward is your direction, where you will encounter two more enemy encounters. For assistance, refer to the map below.
Approaching straight ahead, you will find a bridge with a Secret Key caged at the end. Behind the cage, there’s a green Flesh Node which you can leverage to reach a platform.
Proceed straight ahead to collect Gold and venture back to gather armor plates before reaching an area where you can successfully Shield Throw.
With that, you can now pass through the gate that previously held the Hot Metal. Before jumping down, observe to your right. Leap onto the climbable wall to access a Gold Chest and unlock our fourth secret location.
This path leads directly to the Secret Key, so make sure to seize it!
Secret #5
Cross back over the bridge, taking a right before proceeding through the large archway. Here lies a locked gate that can be opened with your Secret Key, revealing a Ruby outside and a nearby floating Hell Portal inviting exploration!
Visit the locked gate first—marked in the map below—upon entry, you’ll uncover the chapter’s fifth secret area!
Inside, Shield Bash the tree featuring the Hell Portal above, which will kickstart another enemy encounter. Defeating them will grant you access to the Ruby statue outside this room.
Secret #6 and Collectible #3
From the Ruby surrounding this area, direct your attention rightward. Spot a floating island housing a Hell Portal, with a gravity jet positioned just off the ledge (illustrated below) to help you reach it.
Upon reaching the small island, you will unlock the sixth secret location and obtain our third collectible: a Cyberdemon Toy. Transition through this Hell Portal to be transported back near the statue that held the Ruby.
Secret #7
Next, from the location spawned by the Hell Portal, navigate under the bridge where we earlier acquired the Secret Key. Ahead, encounter a Mancubus, Witch, and a slew of other enemies.
Alternatively, there’s a Flesh Node present, allowing access to our seventh secret location alongside a Life Sigil.
Demonic Essence Upgrade (Health)
Continuing with your quest, face the nearest enemy encounter. Vanquish the Leader Cyberdemon here to receive the Demonic Essence Health Upgrade. Don’t forget to obliterate the Hell Cannon within the building as this will unlock previously detached areas of the map.
Secret #8
Exiting through the same path leads you to another route showcasing a key-locked gate needing the Secret Key, which you possess.
Entering will reward you with Gold, a Ruby, and the eighth secret area, leading back to the Flesh Node and Life Sigil mentioned before.
Now, head back to the entrance of the level. Observing your map, a Codex entry awaits on the left side.
Secret #9 and Collectible #4
From the start, make your way to the Codex marked on your map, through a locked gate you can access using the Secret Key.
Unlocking it will unveil the ninth secret area, alongside Gold Bars and a Codex entry ahead. Stay alert for incoming enemies!
Secret #10
Finally, make your way to the second Sentinel Shrine on the map, nearest to the last enemy encounter. Leap down behind the Shrine and veer right through the fleshy moat to discover our tenth secret area, complete with a Life Sigil.
After uncovering the last secret, complete the enemy encounter nearby. Post-battle, extract the battery located at the back of the area. A cutscene will show the damaged Atlan centrally positioned on the map; your duty is to insert the battery into the Atlan to conclude this chapter.
Before heading out, ensure that you collect the Wraithstone (illustrated above), accessible only after the battery extraction.
Now you’re ready to make your way back to the level’s start—prepare to face a barrage of enemies on the route—and ascend the Atlan. A previously sealed door will now be open, allowing you to install the battery and finish the chapter.
