Important notes
☬ This guide divided into chapters 1-14 by the number of chapters in game;

☬ At the end of each section you can see what collectible items each chapter contains;

☬ To gain some achievements you need to correctly increase skills like: Spot hidden, Occultism, Investigation;

☬ To choose R'lyeh responds you should decrease level of Pierce's sanity by turning him into bad situations. This guide also contains section "What affect sanity", if you think you forgot to do something;

☬ Doing such a big guide was hard work, so if you notice I wrote something wrong -- please, write it in comments. Also, if you want to help me and my work, I really appreciate any help, like screenshots, videos, text explanation, etc.
I also really appreciate when you give "likes" and add this guide to favourite, thank you all!

★ To do that, you need to increase your Spot Hidden skill as soon as possible. Hidden objects have green light, so you probably won't miss it. And if you go to the location with hidden objects, you can see circle in left down corner. When you find all hidden objects in this area, there would appear check mark in circle.

The instructions for Chapter 2 are extremely misleading. It makes it seem as though you can go past the two warehouse goons and enter inside, while still being able to go through the other way. But no, the game forces you into the cutscene with Bradley taking you to the mansion. And there's no way to return to before entering the warehouse because the outside gate closes on reload. So now I have to restart the game again just to read the fucking mural on the wall.

More often than not, people finish games like this or get less than halfway through. The sort of people you'll find here are the completionists. The game came out a fair while ago so there isn't going to be a ton of activity. You can waste more time by maybe asking on the subreddit of the game to see if someone has the save you want, or you can just run it again.

Eat my shyt with the RuN tHroUgH aGaIn advice
Germanic Tigress 10 Feb @ 12:01pm 
If you're concerned with getting all achievements, just run it through again. Only takes like 2 hours after the first playthrough
Raziel 10 Feb @ 4:06am 
does anyone have a chapter 11 save? missed the The Rats in the Walls achievement
Hellarious 6 Oct, 2023 @ 4:57am 
I believe that achievement from chapter 7 in your guide is actually from the end of chapter 8

Scholar of the unspeakable
Meet Algernon Drake and accept his help
Germanic Tigress 4 Oct, 2023 @ 9:34am 
I only needed 2 runs
Hellarious 3 Oct, 2023 @ 9:09pm 
how many runs do i need to get all of the achievements?
Endings are 4 so, do not count it/ Just other achievements
ianschaab 12 Apr, 2023 @ 9:06pm 
For "what affect sanity" section, the one for the ch10 is not story related, is missable. You must accept the knowledge to get it
ianschaab 11 Apr, 2023 @ 11:03pm 
In ch3 are 2 occult items. Sara's Book in her room and the Celtic Runes in the office. And the Ritual Circle of course
