DOOM Eternal achievement guide & roadmap

DOOM Eternal (BATTLEMODE) 2 editions, view...

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...

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.

Objective Missable Single-player No glitches

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.
