DOOM Eternal: All Cheat Code Floppy Disk Locations

Let's get...floppy.

DOOM Eternal is a game that points to the franchise’s future but also pays respect to its past with a tonne of easter eggs and collectibles. One such collectible comes in the form of the cheat codes, which you can find scattered across the game’s many levels.

As well as offering you the ability to play the ultimate power fantasy in Mission Select, collecting all of the cheat codes in DOOM Eternal will also net you the ability to play classic DOOM within the Fortress of DOOM.

However, if you’re going for full completion, you will not be able to access the Slayer Gates if you want to unlock the Unmaykr weapon as the Slayer Key for each gate will not appear.

Here’s where you can find all the cheat code floppy disks in DOOM Eternal, separated by level in the index below.

The first cheat you get in DOOM Eternal can be found shortly after you leap over the chasm of a broken train track and meet the Tentacles for the first time. Look out for a crate that you can use to climp up into a chute. Follow that along and you will find infinite extra lives.

In the room filled with loads of boxes that you can smash open, break all of them and then the mechanism will open up to allow you to swing up to the IDDQD cheat by using the monkey bars. IDDQD basically gives you invincibility.

During one of the platforming sections, instead of jumping away like the game wants you to continue, simply scramble up the wall and then find the Silver Bullet cheat floppy waiting for you. It makes enemies die on stagger, which is basically when they glow orange after being damaged.

This cheat code should be fairly difficult to miss as it’s right in your path for level progress. After using some monkey bars to get through a broken window, simply drop in through a hole and find IDFKA, which unlocks all mods at mastery for all your weapons. Neat.

Mars Core Cheat Codes

Onslaught

Right after you are blasted into the building, make your way to the left and through the burnt out wreckage of a ship of some kind. Take a right past all the tentacles and then find the Onslaught code waiting for you just above a hole. This lets you use the Onslaught power-up permanently.

Nekravol Cheat Codes

Famine Mode

Famine Mode

Famine Mode

Instead of passing through the elevators (weird boxes filled with corpses), drop down and then you will enter a room with the Famine Mode cheat. Famine Mode gives you zero loot from killing and damaging demons, so use it with care. You do unlock a trophy/achievement for completing a level with it activated, however.

 

Party Mode

Shortly after you have a fight with a Marauder, venture down a corridor filled with cobwebs and then drop off the ledge, turning around and dashing into a hidden room to get the Party Mode floppy. This will make comedy noises when you gib or explode demons and it’s a lot of fun.

 

Instant Stagger Mode

Right before you jump into the portal to Urdak, double back and go down the hole you jumped up from. Just before you reach the top, there is a small passageway that you can jump through to pick up Instant Stagger Mode. This allows you to Glory Kill any demon after just one hit.

Urdak Cheat Codes

Berserk Mode

Just after you activate one of the celestrial rings, hang a left out of the door and then find a breakable wall. Double dash or jump and melee to break through this wall and then claim the Berserk Mode cheat within. This cheat allows you to rip and tear at all times.

All Runes Cheat

This is a great little secret. To get this cheat, you must use two Sentinel Batteries to unlock the DOOM 2016 skin, which is the west of the Fortress. Once inside, hang a left and then drop through the hall in the wall, dashing down into a secret room. All Runes unlock all the runes at DOOM Slayer’s disposal, though you can still only activate three.

 

Fully Upgraded Suit

This cheat code is only accessible after the Sentinel Prime level. In the center of the Fortress of DOOM, look up at the windows and then shoot the red target that sticks out in the middle window. This will then activate a launch pad that you can use to get up to a chute and the Fully Upgraded Suit cheat that awaits.

Miscellaneous Cheat Codes

QuakeCon Mode

QuakeCon Mode Cheat

To unlock the QuakeCon Mode cheat in DOOM Eternal, you have to use Praetor Suit Tokens to unlock all upgrades for your suit. Note: using the Fully Upgraded Suit cheat does not count, you must unlock them all through regular play. QuakeCon Mode features an audience that reacts to how efficiently you slay.

DOOM Eternal is available now on PC, PlayStation 4 and Xbox One. Also Stadia. From our DOOM Eternal review:

“DOOM Eternal is a bloody masterpiece of glorious violence that may well be the best the series has ever been.”
