DOOM Eternal has 34 trophies counting the platinum on PS4. Other than that, they are similar on all platforms. They don't force you to play in a specific difficulty mode, which makes them globally very accessible. However, some of them require you to play online.
Beware, some trophies may be spoilers, read on at your own risk.
Complete Hell on Earth
All you have to do is complete the first mission in the game.
Kill all the Doom Hunters
The DOOM Hunters act as the end boss in the 4th mission of the game.
Blow a hole in Mars
This trophy is automatically validated during Mission 7
Best the Gladiator in the coliseum
This trophy is won by defeating the boss of Mission 8.
Acquire a new Crucible in Taras Nabad
This trophy is won by completing Mission 9: Taras Nabad.
Beat all encounters and Mission Challenges, and find all Items in Taras Nabad in a single save slot
You'll have to search every nook and cranny of Mission 9 to kill all the enemies, collect all the items and complete the challenges. Walkthrough coming soon.
Kill the Khan Maykr
This trophy is won by defeating the boss at the end of Mission 12.
Kill the Icon of Sin
This trophy is won by defeating the boss at the end of Mission 13.
Complete the Campaign on any difficulty
This trophy is awarded shortly after completion of Mission 13.
Complete Extra Life Mode with 10 Extra Lives in your Inventory
You'll need the Infinite Extra Lives Cheat Code found in Mission 1.
You'll then need to store extra lives in the missions and launch one with the active code. Playing in a low difficulty mode obviously helps to accomplish this.
Complete a Mission with only the Famine Mode cheat on
You must unlock the Famine Cheat Code, found in the secret passage of the Fortress of Doom. As it removes the life and armor packs from the monsters, it's better to reduce the difficulty and choose an easy mission, like the 1st one.
Complete the cheat code collection in a single save slot
There are 14 Cheat Codes in total, you'll have to search the missions as well as the Fortress of Doom to get all of them.
Fully upgrade Health, Armor, or Ammo in a single save slot
You'll need all the Sentinel Crystals in the game for this, which means you'll need to search the majority of the missions, as well as open the 2 corresponding airlocks of the Fortress.
Complete a Praetor Suit Perk category in a single save slot
The Praetor Suit upgrade path is divided into 4 categories. You must unlock all 4 talents within a category. It's actually pretty easy if you search the whole game.
Purchase all Praetor Suit Perks in a single save slot
You'll need to have searched through most of the game to validate this trophy. There are more points available than you need to unlock everything, so it doesn't matter if you miss a few points.
Spend 8 Sentinel Batteries in the Fortress of Doom in a single save slot
The Sentinel Batteries are found among the missions items, but the best way to get them is to complete the 3 challenges of each mission. Don't forget that you can redo them with codes if you need.
Pick up 20 Extra Lives Total in a single save slot
Watch your map and collect all the extra lives you come across during each mission.
Complete the album collection in a single save slot
Another collectible scattered throughout the game's missions. By taking the armor skills to display the secrets and then digging through them, you shouldn't miss them.
Complete the toy collection in a single save slot
Another collectible to collect. As with the albums and codes, search every mission.
Collect all physical Codex pages in a single save slot
There are many Codex pages. Fortunately, they are not really hidden. When you uncover the map, you should find them.
Complete a Slayer Gate
The first Slayer Gate is in mission 2, you have to catch the key high up to open it. Inside, you must defeat all enemie so you may want to consider reducing the difficulty.
Be careful, the codes disable the doors.
Complete all Slayer Gates in a single save slot
There are a total of 6 doors, you'll find them all in our walkthrough.
Acquire the Unmaykr
Once the 6 Slayer Gates have been completed, go to the Fortress of Doom and open the large energy cage containing the weapon.
Master all Weapon Mods in a single save slot
Weapon mods are usually in the path or nearby. You'll unlock them by searching the missions and opening the airlocks of the Fortress of Doom. You then need to invest tons of Weapon Upgrade points to unlock each bonus. Killing all enemies and completing optional battles and Slayer Gates helps in this regard.
Next, you must complete a particular challenge with the weapon module, some of which are more difficult than others. Be aware that towards the end of the game you can find several tokens that will allow you to directly master a model. Save them for the worst challenges.
Perform 33 Unique Glory Kills in a single save slot
Each enemy has several different Glory Kills depending on your position. Here are some methods to have variants: If you are above him (with a double jump for example), attack him from the front or attack him from the back.
Play as 5 different Player Demons in BATTLEMODE
You will have to play each type of demon at least once.
Do 5000 damage as a Player Demon in BATTLEMODE
A matter of perseverance in this case. The Revenant is probably the most aggressive (but fragile) demon of the lot if you want to inflict damage.
Kill 200 opponents in BATTLEMODE
It is probably easier to validate this trophy by playing the Doom Slayer than the demons, given the balance of power.
Play 25 BATTLEMODE matches
It's all in the description, it should allow you to validate other trophies along the way.
Kill a Player Demon with each of the 8 Slayer weapons in BATTLEMODE
This will certainly require some effort on your part. You'll have to think about changing weapons at the last moment for the deathblow, if necessary.
Heal yourself or your teammate for 50000 health in BATTLEMODE
Demons have special powers in BATTLEMODE, you will have to choose one with this bonus.
Kill 666 Demons.
You should validate this trophy without any trouble during the solo campaign.
Bethesda and id Software tell us about a new feature in the upcoming DOOM Eternal that will focus on online features, whether for multiplayer with Battle Mode and Invasion, but also for single-player with skins and master levels.
