Alone in the Dark

1. We go through the game for fun for any of the two characters on medium or high difficulty, with the modern mode turned on so that objects on the map are highlighted. I personally chose Emily since it's more canon to the plot.
2. Vacuum the entire map. Items, hints, dialogues, locked doors and safes. You won’t be able to return to a certain chapter and collect more collectibles, but the game is very linear, collecting everything won’t be difficult, I only missed one item during the game. You will periodically return to the Derseto estate, this is like a base point. With each return, it’s better to search the rooms again, something new may appear, and there aren’t that many rooms there, quickly remember the house + some will close over time. There are unique items, replicas and documents for each of the two characters, so it’s better to look at them in the guides if you’re afraid of missing out. But I would advise you to place special emphasis on these items:
- Death with dignity (secret ending for Emily);
- Hornless Goat (secret ending for Edward);
- The whole world is a theater (shared secret ending);
- Missing children (will give a gun).
3. At the end of the fourth chapter (as Emily), before the battle on the mountain, make a manual save so that you can load and replay the secret ending. But provided that you have collected all the collectibles for this.
4. During the game, be sure to talk to each npc you meet three times until the conversation icon disappears. There are not many characters, but you can miss the trophy if you pass by and don’t talk, although this is extremely difficult to do. Moreover, this needs to be done for both Edward and Emily, at the end of the game you also need to talk to everyone. You can skip the dialogues, you don’t have to listen.
5. After the first playthrough, we can look into the guides, look at what items we haven’t collected, especially pay attention to the tips. I personally made a list for myself of what was missing, fortunately for me it was short: unique collections for the second character + 1 item. Then we select the second character (in my case Edward) and start a new game. Before doing this, delete all manual saves, do not be afraid, all items will be saved when you play again. This is needed for a buggy achievement where you can complete the game without first aid kits. The main thing is not to delete saves from the console.
6. I combined the second playthrough with fast run achievements in 3 hours and a playthrough without healing, so we set the difficulty level to easy. Skip the dialogues and videos (they count against time), look in advance at all the combinations for riddles and puzzles, where and in which chapter are the items that you missed during the first playthrough. Save manually often. If you're stuck for a long time, you can load a save and do everything faster, or if you've lost a lot of HP. You can run around many enemies, turn on constant running on R3 and use dodge O. Time paused in the game also counts, but if you load a save, it does not. Just do not load autosave from the loading menu under any circumstances, otherwise you will not receive an achievement for first aid kits.
7. At the beginning of the fourth chapter as Edward, do not forget to talk to the tree in the garden and make an offering for the secret ending. Then you won't get there. We also make a save for Edward at the beginning of the fifth chapter and knock out three endings for him. Of course, provided that all collections have already been collected.
8. In general, platinum in the game is completed in 10-15 hours if you follow these tips. You can immediately play according to the guides and it will be a little faster, but what fun is there in the game then?
9. Good luck.

As of April 30, the Nobody Knows What Happened trophy does not drop. Moreover, interaction with the loop blocks the ability to continue the game. After activating the memory through the sculpture, a black screen appears and that's it.
