DOOM Eternal achievement guide & roadmap


Two playthroughs are required; the first for all the collectibles and the second in "Extra Life Mode" which is hardcore/permadeath - although you can pick up extra lives as you run through.

This is because {{Master of Fasting}} requires chapter select (to enable cheats) - but chapter select is not enabled when you're in Extra Life Mode.

Difficulty level doesn't affect achievements, so play on whatever level you feel comfortable on!

You can use chapter select (and fast travel) as you progress and afterwards to go back for any slayer gates or collectibles you missed; so everything is Optional, not missable. But not if you're in Extra Life Mode...


Single and multi-player

Darn It, They Keep BREAKING

Objective, Optional, SP-only,

Perform 33 Unique Glory Kills in a single save slot

You'll get this pretty early on, in the first or second mission.   Damaged enemies will flash blue or orange then you can press R3 (on a controller, different on a keyboard) to execute a glory kill.  There's multiple glory kill types for each kind of enemy so this is pretty easy to get...

Crystal Craving

Story, SP-only,

Upgrade Health, Armor, or Ammo

You actually can't avoid doing this, very early on in the game...


Story, Unmissable, SP-only,

Complete Hell on Earth

This One's my Favorite

Complete a Praetor Suit Perk category in a single save slot

Extra Extra Lives

Objective, Optional, SP-only,

Pick up 20 Extra Lives Total in a single save slot

Must be done in Extra Life Mode.  This is a cumulative total - you don't need 20 in your possession at the same time.

This can be farmed in mission 2 (Exultia) - at the very start drop down the left in front of you and there's an extra life there.  Quit to main menu -> Mission Select -> restart mission -> rinse & repeat.   NB you must have already completed mission 2 for this to be available.

Interplanetary Fracking

Story, Unmissable, SP-only,

Blow a hole in Mars


Objective, Optional,

Spend 8 Sentinel Batteries in the Fortress of Doom in a single save slot

There are 27 of these collectibles in total, which is more than you can use in total in the Fortress of Doom - and way more than you need for this achievement.

Thumbs Down

Best the Gladiator in the coliseum

Meet Your Unmaykr

Objective, Optional, SP-only,

Acquire the Unmaykr

You can get this in the Fortress of Doom after having completed all 6 slayer gates during the mission to get the keys; then use the keys on the cage at the back of the fortress and pick up this awesome weapon.

Master all Weapon Mods in a single save slot

Master of Fasting

Objective, Optional, SP-only,

Complete a Mission with only the Famine Mode cheat on

Famine mode can be obtained in mission 10.  After this mission, use mission select and the cheat menu to enable this cheat- then complete a mission.

This cheat makes enemies not drop any health/armor.  They only drop ammo when killed with a chainsaw.   Hell on Earth is probably the easiest level to do this on.

Note you cannot get this in Extra Life mode.

Fight Like Hell

Grind, Optional, MP-only,

Do 5000 damage as a Player Demon in BATTLEMODE

Mix and Match

All-the-things, Optional, MP-only,

Play as 5 different Player Demons in BATTLEMODE

Man vs Monsters

Grind, Optional, MP-only,

Play 25 BATTLEMODE matches

Running Up the High Score

Objective, Missable, SP-only,

Complete Extra Life Mode with 10 Extra Lives in your Inventory

Ofc you need to start the game in Extra Life Mode to get this.  Make sure you don't die too much...   (there are enough extra lives around that you can die a few times though).

This is recommended for a 2nd separate playthrough on the easiest difficulty - although you can do everything all in one run if you really want to.

Truce between Demons

Grind, Optional, MP-only,

Heal yourself or your teammate for 50000 health in BATTLEMODE
