Many secrets lie withinDoom Eternal's massive levels. When you aren't blasting the forces of Hell to pieces, the game offers plenty of optional challenges and collectibles for players to uncover. Music disks, toys, and cheat codes are all scattered across the campaign that players can obtain.

Some of these secrets also reside within the Doom Slayer's Fortress of Doom, a hub-like zone you can explore in between most levels. Inside the fortress, players can find locked rooms that contain powerful collectibles, but there is more to this location than the game tells you. From subtle references to hidden games, here are 10 secrets in the Fortress of Doom you likely missed inDoom Eternal.
Not many people have a mancave as dense as the Doom Slayers. On the lowest floor of the Fortress of Doom contains the Doom Slayer's office, filled with tons of easter eggs and nods to previousDoom entries.
WhileDoom Eternal is missing classicDoom levels as secrets in its campaign missions, id Software went above and beyond throwing a nod at the classic titles. The Doom Slayer's computer has full copies of bothDoom andDoom 2 that are locked behind a few requirements. ForDoom, you will need to collect all 14 cheat codes as a nod to the game's large 4 floppy disk install. As forDoom 2, you will need to type in "FlynnTaggart"for the second file's password prompt to unlock this legendary game.
The new suit for the Doom Slayer inDoom Eternal is one of the series' best, but nothing can compare to the intimidating armor fromDoom 2016.
If you prefer that armor to the new one, you can find and use it within the Fortress of Doom. Head to the right of the Fortress and walk outside of the castle. You will need two Sentinel Batteries to open the door across the walkway. Once opened, you have unlocked the Original Praetor Suit! Head to the main menu and equip it under the customize submenu.
Cheat codes are collectible items inDoom Eternal that enable some crazy modifiers, ranging from reduced ammo drops to permanent Berserk! There are two hidden in the Fortress of Doom that you'll need to find.
The first Cheat code you can find is the All Runes cheat. To unlock this, head to the Classic Praetor Suit tower and head inside. From there, drop down the opening in the wall to your left. You will notice a place to land as you're falling. Head into the bottom of the tower and you'll have your new cheat code! A portal will then open to let you back inside the Fortress of Doom.
A throwback toDoom 64, the Unmaykr is a powerful weapon that can only be obtained by completing all six of the game's difficult Slayer Gate encounters.

These gates are found in numerous campaign levels, each requiring a nearby key to open. Platforming and exploration are usually tied to obtaining these keys, but be prepared for a tough fight once inside. Your reward for that trouble is the powerful Unmaykr rifle residing in the back of the Fortress of Doom. Sharing the same ammunition as the BFG-9000, this gun can kill stunned Marauders in 10 shots and slay the toughest of demons in seconds. It also annihilatesthe game's final bosses. If you need a certain enemy dead but don't want to waste 30 Argent rounds, use the Unmaykr!
Fans ofDoom 3 will be pleased to know that id has not completely ignored the black sheep of the series. It seems the Doom Slayer has a replica of that game's Soul Cube laying on his desk.
Head to his man cave at the bottom floor and you will see it next to the Slayer's mousepad. The Soul Cube was a power weapon inDoom 3 that instantly killed all but the toughest of demons with a single attack. Enemies damaged by the Soul Cube would restore health to the user as well, making it an extremely powerful item for the game's later stages. It is a shame you can't use it inDoom Eternal, but it is still a subtle nod to the most controversial mainDoom entry in the series so far.
As a member of the Night Sentinels, it makes sense that the Doom Slayer received their armor at some point. Fortunately, players can obtain it as a skin!
Similar to the Original Praetor Suit, players can obtain this skin by heading to the left tower in the Fortress of Doom floating outside. After jumping across some floating debris of an ancient walkway, you will need 2 Sentinel Batteries to open the door. Once opened, you unlock the skin. What's most interesting is this suit is very similar to the armor Marauders use, which makes sense considering they are corrupted Night Sentinels.
Fans of the originalDoom will remember Daisy, a pet rabbit of Doomguy that was brutally murdered by the forces of Hell. It seems that Daisy the rabbit has made a return inDoom Eternal.

You can find her cage and food next to the Doom Slayer's desk in his office. There is also a painting of her with the Doom Slayer on a nearby wall. Interestingly, you can find a stray rabbit in every main level inDoom Eternal, though shooting or interacting with the rabbit does nothing. Could this be the Doom Slayer imagining his now deceased rabbit?
Many references to id Software can be found withinDoom Eternal's levels. Players can find their headquarters in the last level, and various food items have the faces of lead members of the team.
In the Fortress of Doom, players can find a box of pizza sitting on the Doom Slayer's desk in his mancave. While this seems insubstantial by itself, fans ofDoom will instantly recognize the person on the box is Hugo Martin, the lead game director forDoom Eternal. You can also see his face in one of the shops in the Arc Complex level.
Doom Eternal doesn't just reference theDoom license. Many easter eggs relating to other games are visible in the Doom Slayer's bookshelf.
Franchises likeDuke Nukem,Fallout,Quake, Half-Life, and evenDeus Ex are poked fun at by these book titles. Popular booksare humorously renamed, such asThe Catcher in the Ryerenamed to "The Caco in the Rye." The Doom Slayer also has copies ofQuake 3: Arena,Doom, and the sixth edition ofDungeons & Dragons.
Arguably the sneakiest secret in all ofDoom Eternal, the Fully Upgraded Suit cheat code requires keen vision to figure out.
Towards the end of the game, before you head to Nekravol, the player will have one last chance to visit their fortress before the final act begins. In the room The Crucible is charging, you can find a hidden button on one of the windows. Shoot it and an air vent will open, allowing you to obtain this cheat code. You must be towards the end of the game for the button to appear.
