Every secret location in Doom Eternal
Much like the classic Doom games, there are a ton of secret items that are hidden all through the game. They’re found not just in the levels, but also the “Fortress of Doom” hub. There are an awful lot of them, so it’s better to just have a look at the individual levels themselves and see what secrets can be uncovered. If you are looking for secret collectables for each mission in the game, you can find those in our full secret collectables guides list:

How to unlock the PC
The old-school desktop PC in the Doomguy’s gaming den has two options to select. The first option allows you to see the installation progress of “something”. This is in fact, the original version of Doom, complete with CRT 4:3 aspect ratio. To unlock classic Doom, you need to collect all 14 cheat code disks. Since these are standard collectables, we figured the best way to let you know where they are is to give you links to their entries within their respective collectable guides.
Doom Eternal cheat code locations
Hell On Earth - Infinite Extra Lives Cultist Base - IDDQD (God Mode) Doom Hunter Base - Silver Bullet Mode Super Gore Nest - Infinite Ammo Arc Complex - IDKFA (Full Armour, Health, and Ammo) Mars Core - Powerup Mode (Onslaught) Taras Nabad - Powerup Mode (Overdrive) Nekravol - Famine Mode Nekravol Part II #1 - Party Mode Nekravol Part II #2 - Instant Stagger Mode Urdak - Powerup Mode (Berserk) Fortress of Doom #1 - All Runes Fortress of Doom #2 - Fully Upgraded Suit Doom Eternal upgrades (Fully upgrade Praetor Suit) - QuakeCon Mode
Upon returning to the Fortress of Doom with all the cheat disks, the option to check the installation will now transform into an option to open Doom. This version is Ultimate Doom, as it includes the fourth episode but it looks to be emulated within Doom Eternal. If you crashed to Windows when attempting to open the classic Doom from the desktop PC, this has now been patched and should now work.
What is the password
The second option on the old-school desktop PC requires you to enter a password. To enter letters, you need to scroll up and down to get the appropriate letters to show. You only need to have the correct letters show to unlock what’s behind it. The password is “FLYNNTAGGART”. Once you’ve got the password correct, it’ll be accepted automatically without the need to press enter. The reward is Doom II: Hell On Earth. It’s unclear which version of Doom II this is as there are no obvious tells if it includes any of the add-on levels that were available separately.
How to unlock the Unmakyr
Would you like to get one more weapon to add to your arsenal? The Unmakyr is a powerful super weapon that uses the same ammo type as the BFG 9000. To unlock the Unmakyr, you need six Empyrean keys. These are found within the first few missions, behind the Slayer Doors. Since these need well hidden Slayer Keys to unlock, here are links to all the locations for the Slayer Keys in the game.

It doesn’t have any weapon mods, but it fires a spread shot that is very powerful. While the BFG still wins in terms of overall damage per shot, the Unmakyr does do a lot of damage to certain enemies very quickly.
Doom Eternal easter eggs
There are various easter eggs in Doom Eternal hidden within Doom Eternal. Here are just a few of the ones we have found so far.
The records you collect are displayed in the Fortress of Doom. They are the pictures hanging from the wall and feature tracks from various id Software games. These include Doom, Quake, and Commander Keen. Press E to look at them, then Space to play the music. Several suits can be unlocked using Sentinel Batteries. One is themed on the classic Doomguy suit. In the same room as the toys and desktop PC, there is an adorable painting with the Doom Slayer in it with his pet rabbit Daisy. Daisy can also be found hidden in each level, just hopping around. You, sadly, cannot pet the rabbit. The third mission - Cultist Base - has a couple of Commander Keen enemies, known as the Dopefish, hidden around the level. Destroying them with explosions from mines or gunshots rewards you with 1-Ups. One is found just after unlocking the first Cultist door if you head right and jump down to the lower ledge. Swing on the monkey bars and you should see a wall with a green monster sticking out of the frozen ice. Standing in lava damages you slowly rather than instantly killing you, but if you run out of lives, there is a rather obvious nod to the Terminator films that happens. The books on the bookshelf have references to literary works and games, including a rather obscure Daikatana reference. This is also where you find a reference to the Doom books in the novel “RET-CONNED: The Life And Times Of Flynn Taggart”. The comics strewn throughout the Doomguy’s gaming room have “Taggart Comics Group” on them, another reference to Flynn Taggart.
