The most important early choice is the tea: sleeping aid and old laxative unlock different achievements. Enter 5364 in the dream, then collect the Gear Boy, batteries and basement cartridge before ending the Chapter.
This guide is the no-miss layer. For the story order that finishes the Chapter, use Chapter 1: Strange Neighbors.
Don't Miss These in Chapter 1
Replay cuts, mutually exclusive awards, and the conversations that look optional. The Chapter route still has the story order if you only need to finish.
◉ Don't miss this: Exhaust dialogue choices. Several Episode One achievements depend on conversations that look optional.
◉ Don't miss this: Check Larry's kitchen and the boarded area on floor five for two of The Unknown sightings.
◉ Don't miss this: Go to Sleep and Irritable Bowels require different outcomes, so use chapter replay to earn both.
- Entering a random dream code and losing the clean Gear Boy route.
- Leaving the basement without the cartridge.
- Assuming both tea achievements can be unlocked in one Chapter run.
- Entering a dream code before locating every clue.
- Leaving the basement without checking Lost and Found for the Gear Boy cartridge.
- Treating one conversation as final when new dialogue can unlock after discoveries.
- If an achievement fails to appear after a clean run, compare the condition against the full achievement checklist before replaying.
Who Causes a Miss in Chapter 1
Skip these conversations or choices and you lock an achievement, a tool, or a later code. The rest of the people on this route are on the Chapter 1 roster.
Sal FisherPlayable lead. The dream keypad and Gear Boy route start with him.
Skip 5364 here and the Chapter 5 shed code is harder to reconstruct.
Larry JohnsonFirst ally in Addison Apartments and partner on the Mansfield case.
Thin dialogue with Larry here makes later friendship and apartment access feel incomplete.
Lisa JohnsonCaretaker dialogue that opens basement access for A Dark Secret.
Skipping the caretaker conversations misses an early route.
Charley MansfieldThe opening murder case. Tea choice locks one of two achievements.
One playthrough cannot unlock both Go to Sleep and Irritable Bowels.How to Unlock Every Chapter 1 Achievement
Story awards follow the Chapter route. Use the timing notes and unlock steps here when you want the complete set, including replay-only outcomes.
Go to Sleep / Irritable Bowels
Best time: Choose the tea ingredient only after you have Addison's tea and are ready to return to Charley.
Watch out: The two outcomes are mutually exclusive, so the alternate award needs a chapter replay.
The Unknown
Best time: Check the morgue, the boarded fifth-floor wall and Larry's kitchen while the apartment route is open.
Watch out: The three sightings are easy to leave behind while following the murder case.
House of the Wretched
Best time: Finish the Gear Boy chapters before ending the case.
Watch out: The device, batteries and cartridge are all needed on the same chapter run.
Charley's Pony
Complete Chapter One.
Story: Finish Strange Neighbors.
Go to Sleep
Use the quiet tea solution.
Missable: Mix Addison tea with the sleeping aid and give it to Charley.
Irritable Bowels
Use the alternative tea solution.
Missable: Mix Addison tea with the old laxative and give it to Charley.
Metalhead
Listen to Sanity's Fall.
Missable: Ask Larry to play the song twice during the Chapter.
The Unknown
Find three hidden supernatural sights.
Missable: Inspect the hidden body, boarded eye and demon in Larry's kitchen.
A Dark Secret
Learn about Larry's curse.
Missable: Complete the optional conversations that lead Lisa to discuss the curse.
House of the Wretched
Finish the Gear Boy game.
Missable: Use 5364 in the prologue, collect the Gear Boy, batteries and cartridge, then complete every chapter.
Final Checks Before You Close Chapter 1
Confirm these while this save is still open. They are the last things that fail after a late sequence.
- Choose one tea outcome; the alternate Chapter One achievement needs a separate replay.
- Pick up the Gear Boy, batteries, and basement cartridge before you close the case.
- For The Unknown, inspect the morgue body, fifth-floor wall eye, and Larry's kitchen demon.
Where Players Get Stuck
Secure the 5364 route in the dream
Read the four visual clues and enter 5364 at the keypad. The correct code matters later for the Gear Boy achievement path, even though the door can be opened another way.
Build the Gear Boy route before the investigation ends
Pick up the Gear Boy in Sal's bedroom, batteries from the kitchen, the basement access route from Lisa, and the game cartridge from Lost and Found. Complete every available Gear Boy chapter before concluding.
Clear the three hidden sightings
For The Unknown, inspect the morgue body, the boarded wall-eye on the fifth floor, and the demon in Larry's kitchen. Do this while the building remains open for exploration.
Choose and record a tea outcome
Use sleeping aid with Addison tea for Go to Sleep, or the old laxative for Irritable Bowels. Finish one path, then replay the Chapter for the other.
Visual Clues
Official Steam screenshots. Use the caption to find the interaction. Codes that let the Chapter continue stay on the Chapter 1 puzzle list.
