Discover all Ruby locations in Doom The Dark Ages. Uncover hidden treasures and enhance your gameplay with our comprehensive guide!
In Doom The Dark Ages, Rubies are an exceptionally crucial resource, serving as the primary material for strengthening your devastating weaponry to their second and third upgrade levels. Given their limited availability and often hidden placements, tracking down each one is vital for maximizing the Slayer's destructive potential. This comprehensive, chapter-by-chapter guide will detail every Ruby location, structured to help you collect them efficiently without unnecessary wandering through the grim landscapes of The Dark Ages.
Doom The Dark Ages: All Ruby Locations
1) Sentinel Barracks – Chapter 4
Your first opportunity to collect Rubies begins in Chapter 4.
- Ruby 1: This initial Ruby is straightforward. Simply stick to the main storyline path, and you will encounter it without needing to search extensively.
- Ruby 2: This one demands more effort. You will need to explore an off-path area. Look for a lower ledge to drop down to, then climb through a narrow space to discover the hidden Ruby.
2) Holy City of Aratum – Chapter 5
In this chapter, both Rubies are cleverly tucked away, requiring environmental interactions.
- Ruby 1: This Ruby lies close to a Hell Carrier. After acquiring a new weapon, be on the lookout for a locked door. Above it, you will see a red lock. Breaking that lock with your shield will allow you to move into the room and collect the Ruby.
- Ruby 2: This Ruby is linked to a secret landing zone. First, find and press the button that drains water nearby. Head down the hole it reveals, use the valve inside to access the Red keycard, and then use that keycard to open a door hiding the second Ruby.
3) Siege – Part 1 (Chapter 6)
This section contains a generous four Rubies.
- Ruby 1: This one is straightforward. Simply go to the marked spot on your map and collect it after dealing with any nearby threats.
- Ruby 2: Swim through a submerged path beneath a caged area. You will reach a switch. Activating this switch grants access to the Ruby located inside the cage.
- Ruby 3: This Ruby requires interaction with several Wolf Statues. You must destroy all of them, then return to the marked spot where you originally found the challenge to find the Ruby waiting for you.
- Ruby 4: You will find this final Ruby behind a door. The trick here is to first locate the area’s secret key. Use it at the specified spot to claim the fourth Ruby.
4) Siege – Part 2 (Chapter 7)
Only two Rubies are available in this part of the Siege.
- Ruby 1: This Ruby is hidden in a locked area. You will need to locate the secret key first. Use it to access a concealed zone filled with enemies. Once the area is clear, you can collect the Ruby.
- Ruby 2: This Ruby can be found after entering an open spaceship zone. Instead of continuing forward along the main path, climb the nearby stack of boxes and make your way upward to reach the Ruby.
5) Abyssal Forest – Chapter 8
- Ruby 1: This Ruby becomes visible after a significant drop into a deeper part of the level. As you descend, watch the side platforms and continue forward while collecting gold. Eventually, the Ruby will come into view.
- Ruby 2: Keep following the main objective path until you find a ballistic cannon. To its left, jump to a distant platform. From there, continue moving forward until you spot the Ruby.
6) Ancestral Forge – Chapter 9
- Ruby 1: Head to the highest point available in this area to find the first Ruby. Utilize the spiraling pathways to reach the top, where it's placed near a toy collectible.
- Ruby 2: This Ruby is behind a locked door. Look nearby for a small gap that lets you aim at a red lock with your shield. Breaking it will open the door, allowing you to pick up the Ruby inside.
7) Forsaken Plains – Chapter 10
- Ruby 1: Begin by finding this first Ruby just outside a Gore Nest. You will need to enter and clear the nest area of all enemies to access it.
- Ruby 2: This one is behind a hidden door. You must track down the key first, then fight your way through enemies beyond the secret entrance. The Ruby will be located at the far end of this area.
- Ruby 3: The last Ruby in this chapter requires the use of an elevator found beside a shrine. Take it up and step onto the high platform. The Ruby can be found here.
8) Spire of Nerathul – Chapter 14
- Ruby 1: At the first landing site, use a nearby jump boost to launch yourself up to some wooden planks. You will find the first Ruby there.
- Ruby 2: This Ruby is found after entering an underwater section. Swim carefully, avoiding any hazards. Once you reach the other end of the underwater passage, the Ruby will be waiting.
- Ruby 3: This Ruby is earned after defeating all enemies in a specified room. Clear it out completely, and you will gain access to the Ruby.
9) Kar’Thul Marshes – Chapter 16
There's only one Ruby in this chapter, but it requires a sequence of actions.
- Ruby 1: Enter the building shown on your map, which will transport you to an alternate area. Start by hitting a distant red lock from an elevated platform. Then, move down and align two visual markers. Once they're in place, throw your shield to destroy the structure that forms. This complex interaction will reveal a path to the Ruby.
10) Harbor of Souls – Chapter 19
- Ruby 1: Begin by riding the elevator at the map-marked location. Use it to reach a platform with a red button. Stand on the button and throw your shield at the energy units across the gap. The door behind which the Ruby is hidden will now open. Crucially, do not call your shield back before you collect the item, as this might cause the door to close.
11) Resurrection – Chapter 20
- Ruby 1: The first Ruby here is prominently placed on a statue. It's in the open and easy to spot.
- Ruby 2: To get the second, you will need a Blue key. Once you have it, open the nearby locked door and head up. The Ruby is placed along the way.
- Ruby 3: The last Ruby is also behind a Blue door. Use the same key to access it. You must defeat everything inside this area to claim the third Ruby.
12) Reckoning – Chapter 22
- Ruby 1: Start with an elevator ride. Before going up, throw your shield at a nearby Blue button. This action triggers a climbing wall. Use the climbing wall to reach a
second button, repeat the process (throwing your shield at it), and
eventually, you will find the Ruby located above.
- Ruby 2: This Ruby is visible behind a door. Drop down to the lower area and use a jump boost to land on an overhead platform. Head across this platform to grab the Ruby.
- Ruby 3: The last Ruby in the game is behind another secret door. The key for this door can be found in the vicinity. Once obtained, go
to the door's location and open it to collect the final Ruby in Doom The Dark Ages.
