Wondering how to get through the Fire Door in Chapter 2 of Doom: The Dark Ages? The 20-odd expansive levels of Doom: The Dark Ages house a number of hidden areas, some much more secretive than others. The majority of these areas in the first couple of chapters aren’t too tricky to find, but if you’re reading this, you’ll likely have already found the exception: a doorway towards the end of Hebeth which is engulfed in perpetual flames that deny all entry.

In this quick step-by-step guide, we’ll show you exactly how to open the Fire Door by first turning off the flames via another hard-to-reach area nearby. With the flames off, you’ll be able to reach the secret area behind and reap the rewards that follow - and ensure your 100% run through Doom: The Dark Ages remains untarnished!

Fire Door puzzle solution:

  1. Look at the wall to the right of the door opposite the Fire Door.
  2. Throw your Shield Saw at the superheated metal lock on the wall.
  3. Vault up into the room and onto the lower level.
  4. Find the valve below the hole in the wall.
  5. Interact with the valve to extinguish the flames.
  6. Shield Charge through the door and approach the Fire Door to open it.

Starting from the Fire Door, turn around and face the closed door opposite. In the room behind that door is the valve you need to find. Partway up the wall to the right of that door, you’ll find the hidden entrance to this room.

2. Throw your Shield Saw at the superheated metal lock on the wall

As you’ve been shown previously in Chapter 2, throw your Shield Saw at the superheated metal lock on the wall to break it open, allowing you entrance into the upper level of the room.

3. Vault up into the room and onto the lower level

The player in Doom: The Dark Ages jumps down onto a lower platform indoors in Chapter 2. Ammo and Armour pickups are on the floor, and on the left of the screen a valve can be seen in the corner of the room. - 6

You can either vault straight up into the room or use the nearby ledge to jump across. Either way, once you’re inside, hop down onto the lower level, where you’ll find various pickups on the ground.

4. Find the valve below the hole in the wall

The player in Doom: The Dark Ages walks towards a valve on a pipe, situated below a hole in the wall. Through the wall can be seen the Flaming Door puzzle of Chapter 2. - 7

Next to the door is a hole in the wall, and below it is the crucial and easily missed key to this whole puzzle: an unassuming valve.

5. Interact with the valve to extinguish the flames

The player in Doom: The Dark Ages turns a circular wheel valve on a pipe in a room in Chapter 2, while looking through a hole in the wall towards a doorway covered in flames. - 8

Follow the on-screen prompt once you’re at the valve to interact with it, at long last extinguishing the flow of flames that guard the Fire Door.

6. Shield Charge through the door and approach the Fire Door to open it

The player in Doom: The Dark Ages walks towards the now-opened Flaming Door near the end of Chapter 2. - 9

That’s the puzzle solved! Now all you need to do is Shield Charge through the exit and enter the secret area guarded by the once fiery doorway. The door will open at your approach now that the flames are gone.

What’s behind the Fire Door?

Alas, the reward for completing such an infernal early puzzle isn’t enormous. Behind the Fire Door is a small corridor heading left, with a few Gold pickups on the floor adding up to a total of 9x Gold. As you walk a little way down the corridor, the door at the end will burst open and a Hell Knight will attack you. Dispatch him with extreme sanguinity, then head through the door to find a Life Sigil.

You can then exit out the other side via another breakable door. Shield Charge through the door, and you’ll be back out in the open near where that pesky Fire Door once resided, ready to continue along your path of mindless destruction through Hebeth.

That’s all there is to the confusing task of getting past the Fire Door in Chapter 2 of Doom: The Dark Ages.

Looking for more Arc Raiders Blueprints? It’s a special day when you find a Blueprint, as they’re among the most valuable items in Arc Raiders. If you find a Blueprint that you haven’t already found, then you must make sure you hold onto it at all costs, because Blueprints are the key to one of the most important and powerful systems of meta-progression in the game.

This guide aims to be the very best guide on Blueprints you can find, starting with a primer on what exactly they are and how they work in Arc Raiders, before delving into exactly where to get Blueprints and the very best farming spots for you to take in your search.

We’ll also go over how to get Blueprints from other unlikely activities, such as destroying Surveyors and completing specific quests. And you’ll also find the full list of all 75 Blueprints in Arc Raiders on this page (including the newest Blueprints added with the Cold Snap update , such as the Deadline Blueprint and Firework Box Blueprint), giving you all the information you need to expand your own crafting repertoire.

What are Blueprints in Arc Raiders?

Blueprints in Arc Raiders are special items which, if you manage to extract with them, you can expend to permanently unlock a new crafting recipe in your Workshop. If you manage to extract from a raid with an Anvil Blueprint, for example, you can unlock the ability to craft your very own Anvil Pistol, as many times as you like (as long as you have the crafting materials).

To use a Blueprint, simply open your Inventory while in the lobby, then right-click on the Blueprint and click “Learn And Consume” . This will permanently unlock the recipe for that item in your Workshop. As of the Stella Montis update, there are allegedly 75 different Blueprints to unlock - although only 68 are confirmed to be in the game so far. You can see all the Blueprints you’ve found and unlocked by going to the Workshop menu, and hitting “R” to bring up the Blueprint screen.

It’s possible to find duplicates of past Blueprints you’ve already unlocked. If you find these, then you can either sell them, or - if you like to play with friends - you can take it into a match and gift it to your friend so they can unlock that recipe for themselves. Another option is to keep hold of them until the time comes to donate them to the Expedition.

Note: The missing Blueprints in this list likely have not actually been added to the game at the time of writing, because none of the playerbase has managed to find any of them. As they are added to the game, I will update this page with the most relevant information so you know exactly how to get all 75 Arc Raiders Blueprints.

Where to find Blueprints in Arc Raiders

Below is a list of all containers, modifiers, and events which maximise your chances of finding Blueprints:

  • Certain quests reward you with specific Blueprints .
  • Completing Trials has a high chance of offering Blueprints as rewards.
  • Surveyors have a decent chance of dropping Blueprints on death.
  • High loot value areas tend to have a greater chance of spawning Blueprints.
  • Night Raids and Storms may increase rare Blueprint spawn chances in containers.
  • Containers with higher numbers of items may have a higher tendency to spawn Blueprints. As a result, Blue Gate (which has many “large” containers containing multiple items) may give you a higher chance of spawning Blueprints.
  • Raider containers (Raider Caches, Weapon Boxes, Medical Bags, Grenade Tubes) have increased Blueprint drop rates. As a result, the Uncovered Caches event gives you a high chance of finding Blueprints.
  • Security Lockers have a higher than average chance of containing Blueprints.
  • Certain Blueprints only seem to spawn under specific circumstances: Tempest Blueprint only spawns during Night Raid events. Vulcano Blueprint only spawns during Hidden Bunker events. Jupiter and Equaliser Blueprints only spawn during Harvester events.

Blueprints have a very low chance of spawning in any container in Arc Raiders, around 1-2% on average. However, there is a higher chance of finding Blueprints in particular container types. Specifically, you can find more Blueprints in Raider containers and security lockers.

Beyond this, if you’re looking for Blueprints you should focus on regions of the map which are marked as having particularly high-value loot. Areas such as the Control Tower in Dam Battlegrounds, the Arrival and Departure Buildings in Spaceport, and Pilgrim’s Peak in Blue Gate all have a better-than-average chance of spawning Blueprints somewhere amongst all their containers. Night Raids and Electromagnetic Storm events also increase the drop chances of certain Blueprints .

In addition to these containers, you can often loot Blueprints from destroyed Surveyors - the largest of the rolling ball ARC. Surveyors are more commonly found on the later maps - Spaceport and Blue Gate - and if one spawns in your match, you’ll likely see it by the blue laser beam that it casts into the sky while “surveying”.

Surveyors are quite well-armoured and will very speedily run away from you once it notices you, but if you can take one down then make sure you loot all its parts for a chance of obtaining certain unusual Blueprints.

Blueprints obtained from quests

One way in which you can get Blueprints is by completing certain quests for the vendors in Speranza. Some quests will reward you with a specific item Blueprint upon completion, so as long as you work through all the quests in Arc Raiders, you are guaranteed those Blueprints.

Here is the full list of all Blueprints you can get from quest rewards:

  • Trigger Nade Blueprint: Rewarded after completing “Sparks Fly”.
  • Lure Grenade Blueprint: Rewarded after completing “Greasing Her Palms”.
  • Burletta Blueprint: Rewarded after completing “Industrial Espionage”.
  • Hullcracker Blueprint (and Launcher Ammo Blueprint): Rewarded after completing “The Major’s Footlocker”.

Alas, that’s only 4 Blueprints out of a total of 75 to unlock, so for the vast majority you will need to find them yourself during a raid. If you’re intent on farming Blueprints, then it’s best to equip yourself with cheap gear in case you lose it, but don’t use a free loadout because then you won’t get a safe pocket to stash any new Blueprint you find. No pain in Arc Raiders is sharper than failing to extract with a new Blueprint you’ve been after for a dozen hours already.

Blueprints obtained from Trials

One of the very best ways to get Blueprints is as rewards for completing Trials in Arc Raiders. Trials are unlocked from Level 15 onwards, and allow you to earn rewards by focusing on certain tasks over the course of several raids. For example, one Trial might task you with dealing damage to Hornets, while another might challenge you to loot Supply Drops.

Trials refresh on a weekly basis, with a new week bringing five new Trials. Each Trial can offer up to three rewards after passing certain score milestones, and it’s possible to receive very high level loot from these reward crates - including Blueprints. So if you want to unlock as many Blueprints as possible, you should make a point of completing as many Trials as possible each week.

Best Blueprint farming locations

The very best way to get Blueprints is to frequent specific areas of the maps which combine high-tier loot pools with the right types of containers to search. Here are my recommendations for where to find Blueprints on every map, so you can always keep the search going for new crafting recipes to unlock.

Dam Battlegrounds

The best places to farm Blueprints on Dam Battlegrounds are the Control Tower, Power Generation Complex, Ruby Residence, and Pale Apartments . The first two regions, despite only being marked on the map as mid-tier loot, contain a phenomenal number of containers to loot. The Control Tower can also contain a couple of high-tier Security Lockers - though of course, you’ll need to have unlocked the Security Breach skill at the end of the Survival tree.

There’s also a lot of reporting amongst the playerbase that the Residential areas in the top-left of the map - Pale Apartments and Ruby Residence - give you a comparatively strong chance of finding Blueprints. Considering their size, there’s a high density of containers to loot in both locations, and they also have the benefit of being fairly out of the way. So you’re more likely to have all the containers to yourself.

Buried City

The best Blueprint farming locations on Buried City are the Santa Maria Houses, Grandioso Apartments, Town Hall, and the various buildings of the New District . Grandioso Apartments has a lower number of containers than the rest, but a high chance of spawning weapon cases - which have good Blueprint drop rates. The others are high-tier loot areas, with plenty of lootable containers - including Security Lockers.

Spaceport

The best places to find Blueprints on Spaceport are the Arrival and Departure Buildings, as well as Control Tower A6 and the Launch Towers . All these areas are labelled as high-value loot regions, and many of them are also very handily connected to one another by the Spaceport wall, which you can use to quickly run from one area to the next. At the tops of most of these buildings you’ll find at least one Security Locker, so this is an excellent farming route for players looking to find Blueprints.

The downside to looting Blueprints on Spaceport is that all these areas are hotly contested, particularly in Duos and Squads. You’ll need to be very focused and fast in order to complete the full farming route.

Blue Gate

Blue Gate tends to have a good chance of dropping Blueprints, potentially because it generally has a high number of containers which can hold lots of items; so there’s a higher chance of a Blueprint spawning in each container. In my experience, the best Blueprint farming spots on Blue Gate are Pilgrim’s Peak, Raider’s Refuge, the Ancient Fort, and the Underground Complex beneath the Warehouse .

All of these areas contain a wealth of containers to loot. Raider’s Refuge has less to loot, but the majority of the containers in and around the Refuge are raider containers, which have a high chance of containing Blueprints - particularly during major events.

Stella Montis

On the whole, Stella Montis seems to have a very low drop rate for Blueprints (though a high chance of dropping other high-tier loot). If you do want to try farming Blueprints on this map, the best places to find Blueprints in Stella Montis are Medical Research, Assembly Workshop, and the Business Center . These areas have the highest density of containers to loot on the map.

In addition to this, the Western Tunnel has a few different Security Lockers to loot, so while there’s very little to loot elsewhere in this area of the map, it’s worth hitting those Security Lockers if you spawn there at the start of a match.

That wraps up this primer on how to get all the Blueprints in Arc Raiders as quickly as possible. With the Expedition system constantly resetting a large number of players’ Blueprints, it’s more important than ever to have the most up-to-date information on where to find all these Blueprints.
