How to unlock the Lost Nightmare achievement in Doom 3 - Definitive Guide

Here are the locker codes for Lost Mission:
054 = 631
108 = 847
104 = 579
965 = 428
071 = 532
805 = 372
806 = 372

If you've already beaten the main-campaign and RoE this will be your victory lap to piss all over demons. My nightmare playthrough was more fun than the Marine/PDA collecting playthrough prior to it since the cube means you can yeet Horsedemons, Summonguys and Hellknights out of existence immediately and you get both Shottys almost immediately turning regular encounters into the same trial and error as the other 2 campaigns.

Bosses aren't even worth mentioning. Spider thing reskin and Guardian show up almost back to back and are both defeated by Soulcube followed by BFG. "Final" boss died after 5-7 BFG shots after getting hit by the soulcube.

As always, you can savescum as much as you want trivialising every encounter.

Total (successful) playtime at the end should be roughly 90minutes.

Oh right, and one last thing - if you're having trouble with the elevator/spider room there's an exploit where you can lock yourself out of the room and watch the spiders slowly commit sudoku. Takes 4-5 minutes until they're done but might save some headache since these things like to leap at you instakilling you in the process.

This is the third and final Nightmare achievement. You’re almost done. This campaign is farily short, consisting of only seven levels. It isn't much harder than the base game or RoE, and you are given the Soul Cube. Follow the basic tips for "DOOMed Nightmare" and this shouldn’t be a problem.

It opens after beating the game on veteran difficulty, almost everything is the same as on veteran, except that your health constantly drops by 5hp until it drops to 25. One of the advantages is that an artifact from the main company is available from the start, which you can kill especially nasty mobs and heal.
The main thing is to save after one or two rooms and there will be no problems

Sometimes such saves play a cruel joke. You need to save it constantly and in a full save.
