Doom Eternal: How to Get Secret Above Crucible in Fortress of Doom

Doom Eternal is full of secrets to find, some of which are pretty well hidden. You’ll also find some in the game’s new hub area, the Fortress of Doom. So that you can get the fully upgraded suit cheat, here’s everything you need to know about how to get the secret above crucible in the Fortress of Doom in Doom Eternal.

You won’t actually be able to see it until later in the game, once you’ve obtained the Crucible Sword and Samuel Hayden has returned to your ship. Once the weapon is floating in a platform behind where you access the portal, you’ll spot a yellow question mark above it, by the ceiling.

You can’t just jump up to it, nor is there a hidden way to get around to it from another part of the ship. Instead, you have to do something that’s pretty hidden nearby.

How to Get Secret Above Crucible in Fortress of Doom in Doom Eternal

When you’re facing the Crucible, with the main room of the Fortress of Doom directly behind you, look up to your right at the stained glass windows. You’ll spot a little red dot on the one in the middle, which is a bit out of place.

You need to shoot that with any weapon and a red boost pad will activate behind you.

Run over to that and you’ll be boosted into the air, landing in a small section of venting. Find the second exit hole in that system, which should be just next to where you got into it.

Look through that hole and you’ll see the glowing yellow question mark below you. Drop down and you’ll pick it up. It is the Fully Upgraded Suit Cheat Code, which you can use when you’re playing a mission again.

That’s everything you need to know about how to get the secret above crucible in the Fortress of Doom in Doom Eternal. For more tips and tricks on the game, be sure to check out our wiki guide or search for Twinfinite.
