It just wouldn’t be a Doom game without a haul of cheat codes allowing you to do anything from granting the slayer constant power ups, to instantly unlocking all Rune or Praetor Suit upgrades. Heck, you can even make it so there’s a crowd that cheers on all of your ripping and tearing, or replace all of the glorious showers of gibs and gore with confetti. Doom Eternal cheat codes will stop you from accessing all of the Doom Eternal Slayer Gates, but other than that you’re free to use them as you see fit.
We find that using Doom Eternal cheat codes is particularly useful for charging back through levels to hoover up any missed collectibles, especially when you combine infinite ammo with the BFG or Doom Eternal Unmakyr.
We’ve been punching through walls finding hidden passages so you don’t have to, so we’ve prepared a full guide on how and where to find all of the Doom Eternal cheat codes. There are a total of 14 cheats to collect throughout the main campaign and they’ll be signposted by the game’s telltale floating question marks.

- Fully Upgraded Suit

Infinite Extra Lives location
Player has infinite extra lives.
This Doom Eternal cheat code is found in the Hell on Earth mission after encountering the first tentacle monster in the subway station. From the tunnel there is a right turn, the path then goes left, follow it until you come to an intersection with a crate on the right. Hop up into an air vent and run all the way to the end where you’ll see the Infinite Extra Lives cheat code.
Sentinel Armor is active for the whole mission.
This cheat code is found on the Cultist Base mission after acquiring the Super Shotgun and ascending to an arena with several cages that you need to melee open. After opening all of these and slaying the demon treats within, look at the central cage and use the monkey bars on either side to swing around to a raised platform inside the cage. This is where you’ll find the Sentinel Armor cheat code for Doom Eternal.
Instant Stagger Mode LOCATION
One hit from projectiles, explosions, flame belch, or dashing instantly staggers demon. It has no effect on unique bosses.
This is the second cheat code that you’ll find on Nekravol Part II and is found after you break both titan chains, but before you go through the portal. Head back to the elevator that brought you to this arena, jump down, turn 180, and you should spot a small tunnel that has the cheat code inside it.
All Runes LOCATION
All Runes unlocked.
This one is actually on the Fortress of Doom itself. If you’re facing the central console that leads to new missions, then the cheat code is located in the external tower to the right. You don’t need to open up the tower to get the cheat code, but it is much easier if you do. To grab the code without opening the door, position yourself on the left edge before the door and double dash left around the tower, there is an opening below that you’ll need to land in. This is tricky as the game will assume you’ve fallen to your death here, so we do advise just opening up the door with Sentinel Batteries, then dropping straight down via the opening in the left wall.
Infinite Ammo LOCATION
All weapons have infinite ammo.
This cheat code can be found in the Super Gore Nest level, right below the titular gore nest. If you’re staring straight at the gore nest then you need to circle to the left and you should see a mouth with a breakable wall just above the lava. Jump across and dash through the wall, keep going down the tunnel and you’ll catch the Infinite Ammo cheat code no problem.
All weapons are unlocked and mastered and all equipment is unlocked.
This Doom Eternal cheat code is located in a laundromat in the Arc Complex level. This room is just after the large atrium where you find the level’s Slayer Gate. After defeating all of the demons in this area you need to find an open window and use a monkey bar to fling across to another building. Look at the ground and you should spot a small hole in the floor with a very obvious floating question mark inside – go grab it.
Powerup Mode: Onslaught LOCATION
Infinite Onslaught powerup is active for the whole mission.
This one is on the Mars Core mission and is pretty easy to find after firing yourself out of an artillery gun and finding yourself in a space station packed with tentacle demons. As soon as you come across a room that’s littered with tentacle demon spawns, head in and immediately right. There should be a hole in the floor, but just to the right of that is a giant floating question mark and the Powerup Mode: Onslaught cheat code.
Silver Bullet Mode LOCATION
Staggered demons die from a single hit from projectiles, explosions, flame belch, or dashing.
You’ll find this cheat code on the Doom Hunter Base mission, after passing through a constricting laser grid obstacle and climbing onto a lava-spilling moving platform. Shortly after this you’ll arrive at a climbable wall that wraps around a giant pillar. The main mission path requires you to jump to this, climb around, and then jump off and enter a fight in a new area. However, if you turn around before leaving you’ll spot that the climbing wall actually takes you right to the top of the pillar, where you can find the Instant Stagger Mode cheat code.
Fully Upgraded Suit LOCATION
All Praetor Suit Perks are unlocked.
You can find this on the Fortress of Doom hub world, and you may have already spotted it as it’s infuriatingly hidden in plain sight right behind the front section of the ship and just before the Unmakyr container. So, how do you get up there? Look around the room and you’ll notice plenty of stained glass windows. On one of them there’s a small glowing red target – shoot that and a jump pad will appear that allows you to reach the collectible.
Powerup Mode: Overdrive LOCATION
Infinite Overdrive powerup is active for the whole mission.
You can find this cheat code on Taras Nabad near a hidden away gore nest that’s just after the Catacombs section but before the fallen titan. You’ll come across a room full of barrels, as you enter the room, look to the left and you should spy a breakable wall – this leads to a gore nest and the Powerup Mode: Overdrive cheat code.
Famine Mode LOCATION
Demons do not drop health or armor on death.
This one can be found in the hellish Nekravol level. You’ll need to venture quite far into this level to get the Famine Mode cheat code. It’s located just after the arena with the single rotating spike machine, where you exit by using a corpse cage as an elevator. After exiting the arena and fighting a Marauder in the next corridor you should notice a pair of corpse cage elevators to your right, wait for a gap then hope down and you can find a secret lower level that contains a Crucible pickup and this cheat code.
Party Mode LOCATION
Demons burst into confetti on full body gib, lower body gib, upper body gib, limb loss, and fatal headshots.
This cheat is located on Nekravol Part II and is found after the first major battle in the large arena with all the swirling blue, er, soul juice? After finishing the battle there is a corridor to the left side of the room, head down this and watch out for a big drop at the end. First, jump down to a small ledge on the left, then look back to where you’ve jumped from and look down. There is a small breakable wall so lower yourself and smash through it to get your hands on the Party Mode cheat for Doom Eternal.
Powerup Mode: Berserk LOCATION
Infinite Berserk powerup on map start. Only works on ‘Hell on Earth,’ ‘Exultia,’ ‘Super Gore Nest,’ ‘Arc Complex,’ and ‘Mars Core.’
This is found on Urdak after aligning the second ring. Head left out of the control room and look left again and you should notice a rocky alcove with a small tunnel – jump in and hop up a ledge and you’ll find the Berserk cheat code in Doom Eternal.
QuakeCon Mode LOCATION
An invisible audience cheers based on how you play.
Doom Eternal how to activate cheats
Wondering how to turn on cheats in Doom Eternal? It’s pretty easy, actually, but you can only activate cheats between the many Doom Eternal missions. You can do this by either using mission select in the main menu, or by selecting a mission in the Fortress of Doom. Once you’re on the mission select screen just press the R key to bring up the cheat codes menu, which allows you to choose which cheats you want to turn on and off.
This one isn’t hidden away and is instead a reward for reaching a certain point of main campaign progression.
