Welcome to the Doom Eternal Trophy Guide! Doom Eternal has a small and straightforward trophy list consisting of only 34 trophies. It’s simple: beat the story and get all Collectibles (there are many types, all of them are needed for trophies, nothing is missable). Then play through the “Extra Life Mode”. Lastly finish the online trophies. You can play everything on the easiest difficulty, including the Extra Life Mode. A fairly standard list with an easy platinum that is doable for every gamer.
First you’ll want to play through Doom Eternal’s Story Mode on any difficulty. Do NOT pick the Extra Life Mode from the beginning (it’s a Permadeath Mode). Not because it would be hard (it isn’t because you can play it on easy) but for two other reasons: First, there is no Mission Select in Extra Life Mode so you have no way toget missingCollectibles or Trophies. Secondly, you can’t use Cheats in Extra Life Mode which means you can’t get trophy “Master of Fasting”.The Cheat Collectible it requires is found very late in the game. This means even if you’d finish Extra Life Mode first, you’d have toplay through Standard Mode again to find and use that Cheat Collectible.
Therefore, it makes no sense to start in Extra Life Mode, it would only make things more challenging andyou wouldn’t get around a 2nd playthrough either way.
What difficulty you pick for your first playthrough does not matter. You can do all trophies on the lowest difficulty “I’m Too Young To Die”.
Make sure you get all Collectibles as you play through the game. At the end of each mission you unlock Fast Travel. This allows you to revisit all areas in that Mission to mop up Collectibles right away. All Collectibles are pointed out by a Question Mark “?” on the map when you get near them. To make it easier, buy the Praetor Suit Exploration Upgrade “Item Finder” (becomes available in 3rd Mission). It reveals all Collectible Locations on the map. Some are still tricky to find though, as they require solving environmental puzzles. None of the collectibles are missable as you can use Mission Select at any time (except in Extra Life Mode which doesn’t let you replay missions).
Glitch Warning: There are some cases where players reported certain collectibles (particularly Slayer Gate Keys) not spawning. Trying via Mission Select doesn’t fix it. The only thing that worked was to use the pause menu 
and click “Reset Mission” before finishing it. You should go for all Collectibles on the 1st playthrough of the mission. In case something is bugged you will know right away and can Reset the Mission. It’s highly recommended to make a manual backup every few missions to be safe (PS4 Settings > Application Saved Data Management > Copy to USB/PS+). In the worst-case scenario you can copy back your save so you don’t need to start from scratch.
Extra Life is a Permadeath Mode. However, you can play it on the easiest difficulty and there are lots of Extra Lives placed throughout the game. Dying from enemies or falling down doesn’t mean Game Over, it simply means you lose one of your collected Extra Lives. Since you can play on the lowest difficulty andfinished the game before it really won’t be a challenge. You might die once or twice but there are like 40+ Extra Lives placed throughout the levels. You can also skip the Slayer Gates (hardest encounters) because you already did them for collectibles in the 1st playthrough.
There are some timed countdown sections that can result in an instant Game Over if you take too long (won’t let you use an Extra Life). Anything with a countdown (e.g. Mission 5 Timer that goes down) can kill you instantly.
Luckily, it will still make save games. You don’t need to do it in one sitting.If you are dangerously low on extra lives, make a manual save game backupby going to PS4 Settings > Application Saved Data Management > Copy to USB / PS+ to back up your save. To be safe just back up your save after every mission. If for some reason you should run out Extra Lives you can copy back the save. Then you have your progress back.
There are 5 Trophies tied to BATTLEMODE which is the Multiplayer of Doom Eternal. Luckily, all 5 of these trophies can quickly be boosted in private matches but it requires 3 players to boost. Either way these trophies aren’t hard. The only somewhat time-consuming tasks are playing 25 matches and getting 200 kills.
Glitch Warning:Some players have reported online trophies not unlocking correctly (particularly “Weapons Expert”). Should this happen to you, delete your save game and it will wipeall of your online progress and stats. The only thing it actually saves online is your Event XP progress.
Earn all Trophies
Complete Hell on Earth
Kill the Doom Hunters
The Doom Hunters are the 3 cyborg demons bosses at the end of the mission ‘Doom Hunter Base’. You can damage them by overloading their shields with the Plasma Rifle and then using whatever else in your arsenal to damage them whilst their shields are down, then finish them off with a glory kill once their health is low.
Blow a hole in Mars
This trophy is awarded when you complete the mission ‘Mars Core’, after you launch yourself into the core of mars.
Best the Gladiator in the coliseum
The Gladiator is the boss that you fight in the mission Sentinel Prime, and is the only combat in that entire level. It is a large humanoid boss with a shield that attacks in somewhat a similar way to the Marauder. For its first phase when it has its shield you need to shoot the shield whenever it blinks and then momentarily flashes green, which will stagger the Gladiator allowing you to deal a bit of damage. During its second phase it will have two whips and continually attack you with both, so you just need to avoid its attacks when it is doing normal swipes. When it blocks off two sides of the area so you cannot move, you then need to go under or jump over the waves it sends towards you to avoid damage.
Acquire a new Crucible in Taras Nabad
This trophy is awarded at the end of the mission Taras Nabad, after you fully acquire and then try out a new Crucible.
Kill the Khan Maykr
The Khan Makyr is the boss you fight at the end of the mission Urdak, and is fought after realigning all of the teleporter rings before exiting the level. You fight her in a large circular arena while a number of Makyr Drones continually spawn. She launches large area attacks that set the ground on fire, and launches projectiles at you. The whole fight is largely the same, you pump a bunch of damage into her to stun her, then use your Super Shotgun secondary to pull yourself towards her then Blood Punch her. Repeat this 6 times to complete the fight.
Kill the Icon of Sin
The Icon of Sin is the final boss of the game that you fight at the end of the mission Final Sin. This is a large humanoid bull that you face in two large building arenas, where it attacks you with its fists and projectiles while spawning large amounts of enemies. For the first phase it stays on one side, then during the second phase it will walk around all four sides of the building you are on. Both phases operate the same. You need to shoot each of the 8 places on its body to damage it until all 8 pieces are broken. There are plenty of fodder enemies around and ways to get ammo, so you just need to continually make sure you are aware of your resources while putting damage into the Icon while cleaning up other enemies.
Complete the Campaign on any difficulty
What difficulty you play on doesn’t matter for this. You are allowed to play everything on the lowest difficulty “I’m Too Young To Die”.
Beat all encounters and Mission Challenges, and find all Items in Taras Nabad in a single save slot
See Doom Eternal Taras Nabad Collectible Locations Guide.
The first challenge you will complete while working on all collectibles for this level, as there are 7 codex pages you need to collect.
The second challenge you only need to freeze any 10 enemies during the level, not 10 at once or at any specific point, so just make sure to be using your freeze bomb from the start of the level (you can change between grenade and freeze bomb by pressing 
and fire it with 
).
The third challenge will require the most effort, because you need to do 3 different Glory Kills on Pain Elementals, meaning doing 3 of the unique animations. There are 4 – 6 Pain Elementals during the level and you can restart checkpoints to do this if you need so there are more than enough opportunities. They have a tendency to randomly die though if you are shooting them with higher power weapons, so while trying to do this it would be better to clear out nearby enemies then lower the Elemental’s health with the Plasma Rifle to get it to the stunned state. Then you position yourself in either the front, back, top, or side of the elemental to perform one of the Glory Kill animations. When you do one of the unique ones that you haven’t performed before you will have the challenge tracker come up on the side of the screen showing you performed a new one, so you will know if you did a repeat and need to try again.
Once you have collected all items and completed all challenges you will be awarded this trophy upon completion of the mission.
Complete a Mission with only the Famine Mode cheat on
See Doom Eternal Nekravol Collectible Locations Guide.
Once you have obtained this cheat, you can then enable it during level replays from the mission select menu. In Mission select press 
to bring up the cheat menu, then enable only the Famine Mode cheat. This cheat makes it so enemies don’t drop health or armor when killed, only ammo when they are killed with the chainsaw. You can only pick up health or armor from the pickups around the map. For the easiest time you can do this on the level Hell on Earth, which has mostly fodder enemies, then the occasional Arachnotron and Cacodemon. Most enemies you can just run by, outside of the combat encounters where you need to kill everything in order to progress. Once you reach the end of the level with this cheat on you will be awarded the trophy.
Beware, this trophy is unobtainable in “Extra Life Mode”. The reason being that this mode has no Mission Select (even after finishing it), thus no way to enable Cheats.
Complete Extra Life Mode with 10 Extra Lives in your Inventory
This is basically a Permadeath Mode, but there are green Extra Lives placed throughout the missions.As long as you have an Extra Life left it won’t give you a Game Over (exception: when there are timer countdowns and you take too long, e.g. Mission 5, it will instantly give a Game Over). If your health goes to 0 from enemies or falling it just consumes an extra life.
You can find extra lives in all levels in the game and you need to make sure you have at least 10 upon completing the final mission. This shouldn’t be a problem on the easiest difficulty but bear in mind if you die it expends a life right there on the spot and saves, so you cannot recover it. Make sure to makesave game backup after every mission or if you ever run dangerously low on Extra Lives (PS4 Settings > Application Saved Data Management > Copy to USB/PS+).
The Doom Eternal All Collectible Locations Guide includes all extra life locations for all missions.
