Doom Eternal: Cheat codes - how can I unlock them? Doom Eternal guide, walkthrough
Last update: 24 March 2020
On this page of our guide to Doom Eternal you will find valuable tips for clumsy people who have some problems with the game's difficulty or who simply like to cheat a bit and have some fun. We explain how to unlock cheat codes in Doom Eternal. We have also prepared a list of cheats with information on what they do and where to find them.
You can still get the collectibles and try to complete Secret Encounters while playing with cheats. This way, you can help yourself with completing missions in 100 percent. The only feature that isn't available to players using cheats is Slayer Gates. Also, cheats don't block you from getting trophies.
In order to use cheat codes you will need floppy disks, which are one of the collectibles available in the game. The floppy disk example is shown in the picture above. You can find information about where to find such items on the following text and the Secrets page (in the world atlas).
Each floppy disk unlocks a different cheat code, for example, infinite number of lives, immortality or infinite amount of ammunition.
In order to use cheat codes, you must return to the Fortress of Doom, which is the hub of the game visited in between the main missions. Find the mission terminal in the fortress (Mission Select).
Unfortunately, cheat codes cannot be used when you play a particular level for the first time. You can only use cheats when you are repeating a previously completed mission.
You can activate all available cheats or only selected ones. There are 14 floppy disks with different cheats to be found in the game world. The list of all available floppy disks and cheats in Doom Eternal can be found below.
Infinite lives
Infinite lives mean that you will never die and see the Game Over screen.
You can find this floppy disk in mission 1.
IDDQD
Activates immortality. The hero's armor becomes indestructible - you won't lose any armor points.
You can find this floppy disk in mission 3.
Instant stagger mode
This cheat makes demons enter instant stagger. It happens after a melee attack, shooting from a weapon or using one of the hero's skills. This cheat doesn't work on bosses.
You can find this floppy disk in mission 11.
All runes
You get access to all 9 runes.
You can find this floppy disk in the Fortress Of Doom.
Infinite ammo
You get unlimited ammunition supplies for all firearms. This also works on the BFG 9000 - you will be able to fire it any number of times.
You can find this floppy disk in mission 5.
IDKFA
You can unlock access to all weapon upgrades (complete equipment) and all weapon masteries.
You can find this floppy disk in mission 6.
Onslaught

You can find this floppy disk in mission 9.
Famine mode
This is the only cheat that makes the game more challenging - the demons don't drop any loot (health, armor, or ammunition). Completing any mission with this cheat enabled is required to unlock the Master of Fasting trophy/achievement.
You can find this floppy disk in mission 10.
Party mode
This is an easter-egg, not a cheat that makes the game easier. Defeated demons can turn into confetti.
You can find this floppy disk in mission 11.
Berserk
You can turn on the "Berserk" power-up and have it active throughout the mission. In this mode, the hero rips and tears demons.
You can find this floppy disk in mission 12.
QuakeCon Mode
This is an easter-egg, not a cheat that makes the game easier. An unseen audience cheers you throughout a mission.
You can get this floppy disk by making progress in the campaign. In our case, the cheat was unlocked the moment we got They're ALL My Favorite trophy.
