Like many of its predecessors, DOOM: The Dark Ages is packed full of secret areas. Most of them can only be found by thoroughly exploring the map, but this isn't always the case. During the second half of the game's second chapter, players will walk past a broken pipe spewing red-hot flames over a doorway and will need to find a way to extinguish these flames to get inside.
DOOM The Dark Ages Tips and Tricks
With these DOOM: The Dark Ages tips and tricks, beginners can ensure that they're getting the most out of their first playthrough.
At first, it seems as though players might need to access the area above the doorway to find where the pipes lead, but an invisible wall prevents them from doing so. Following the structure round will lead them to the exit of the secret area, but this door can only be opened from the other side. As such, opening the fire door in DOOM: The Dark Ages requires a slightly different approach.
How to Open the Lava Door in DOOM: The Dark Ages
In order to stop the flames, players should continue past the broken pipe and head up the nearby steps. If they look to their left here, they'll see a climbable wall, which will take them to a rooftop area with a few pieces of Gold. After collecting the Gold, they'll want to throw the Slayer's Shield Saw at the red metal cross on the wall over to their right and then jump through the resulting hole.
Inside this new structure, they'll need to look for a valve to the right of the doorway and then press either the Circle (PlayStation) or B (Xbox) button to interact with it. Turning this valve will stop the flames, and the door will automatically open, thus granting access to the secret area on the other side. Sadly, the rewards for opening the lava door are a little underwhelming.
What's On The Other Side of the Fire Door in DOOM: The Dark Ages?
Inside the fire door secret area, players will find nine pieces of Gold and a Life Sigil, as well as a solitary enemy and some ammo and health pickups. Once they're done looting everything, they can throw their shield at the hot metal cross on the exit gate, which will take them back to the outside area, where they can continue on with the chapter as normal.
