Get rid of Victor’s fleshlight.

Open the locked door near the pool table and climb down the ladder inside.

The code for the padlock is:

Watch the Scarlet Lodge cultist defecate for 3 minutes.

-- Chapter 11: Dancing in Red --
Before entering Lusst'ghaa stand next to the girl and stare at the cultist in the cage for 3 minutes.

Spare or save every character important to the story whenever you have the choice.

-- Chapters 11, 12, and 15 --
Spare Dr. Austerlitz (11), Jonathan (12), save Mabel (15), and spare Mutated Amanda (15) (agree to sleep with her) when prompted during the story.

To save Mabel:
After speaking to Mabel at the top of the stairs, go back to Theodore and ask him to save her.
Threaten him and he will tell you to get a bottle with a sun on it from his study in the attic.
Return the bottle to Mabel before entering Lusst'ghaa.

Note: the achievement will unlock after the epilogue, not after sparing Amanda.

Kill every character important to the story whenever you have the choice.

-- Chapters 11, 12, and 15 --
Kill Dr. Austerlitz (11), Jonathan (12), don't save Mabel (15), and kill Mutated Amanda (15) (refuse to sleep with her) when prompted during the story.

Ignore Mabel and follow Amanda straight into Lusst'ghaa.

Note: the achievement will unlock after the epilogue, not after killing Amanda.

Commit suicide due to low sanity.

While you are at 0 sanity, if you have a weapon equipped and lose sanity again you have a chance to commit suicide.
Given the chance for this to either happen or not it can be a pain to get this achievement.
The best checkpoint I could find to let you re-roll the chance was:

-- Chapters 14 and 15 --
After setting off to find the mask of Ughro'ecna, do not heal your sanity going forward.
If you run past every sanity-reducing item below, you will be left with 0 sanity for the first Amanda fight.

Beat her and run into the jumpscare below in the catacombs before her ambush.










If Victor does not kill himself, reload the last checkpoint (right after beating Amanda) and try again.
