Table of Contents:
Route 1 Achievements
- “_ in a Box”

Don’t grow a spine.
- After the dream sequence in the car, you must choose between “Andrew” or “Andy.”
- Selecting “Andy” will lock you into this achievement, which is automatically unlocked upon reaching the corresponding ending.
- To experience both endings, save your game before making your choice in the car.
- “Full Marks!”

Got full marks on a… test?
- If you selected “Andrew” in the car, continue through Route 1.
- After summoning a demon via an unavoidable massive summoning circle, you will be transported to a room with an outlined body.
- Once the phone rings, answer “False” to all three questions to unlock the achievement.
- “Little Mathematician”

Did Leyley’s homework right.
- Shortly after the previous segment, you’ll be in your apartment where Leyley asks you to sign her suspension letter.
- Before signing, interact with the couch where her homework is.
- Solve the math questions correctly, and the achievement will pop up. (If you’re stuck, consider using basic arithmetic skills!)
- “Sister Slaughterer”

Ran out of Ashleys.
- After the homework section, you’ll reach a stage where you must place four people/mannequins.
- Enter the back room to discover multiple Ashleys.
- Eliminate them all to unlock this achievement.
- “Decaying Along”
Survived Episode 3: Decay.
- Simply complete Route 1 to the end of Episode 3, and this achievement will be yours.
Route 2 Achievements
Important Setup for Route 2:

- After exiting the gas station, navigate through the forest puzzle with moving rocks.
- On the third screen, choose the upward path instead of the left path to find an engagement ring (essential for one of the endings).
- In the car, choosing “Andrew” will allow access to both endings (“Shots and Such” and “Splat!”). Choosing “Andy” forces you into the bad ending “Splat!”.
- “Prophecy Fulfiller”

Win at tag, just as the prophecy foretold!
- After entering the demon realm post-camper massacre, Andrew will chase Ashley.
- When Ashley reaches a dead end, you must successfully catch her.
- If you fail, the game lets you retry, so no need to stress about saving beforehand.
- “Splat!”


Reached the Deadest of Dead-ends End.
- Late in the route, you must choose between dropping the engagement ring or holding onto it.
- Selecting “Drop the Ring” and proceeding to the end will unlock this achievement.
- If you chose “Andy” in the car, you are locked into this ending and cannot reach the good ending.
- “Shots and Such”

Reached the Shots and Such ending.
- To unlock this achievement, ensure:
- You have picked up the engagement ring.
- You selected “Andrew” in the car.
- When prompted, choose to hold onto the ring.
- This choice will lead to a different ending and unlock the achievement.
Other Achievements
- “Time Capsule”

Found a time capsule.
- During the Episode 3A prologue, Grandma asks you to gather blueberries.
- Before heading out, grab the Trowel near the house.
- In the forest, go to the bottom-left corner to find a diggable mound.
- Open it to discover the time capsule and earn the achievement.
- “Undetected”

Left the gas stop relatively unnoticed.
- While at the gas station, Ashley will be in the restroom when two police officers enter.
- Hide behind the magazine stall and wait.
- When an officer moves to grab a sandwich, quickly move to avoid detection.
- Knock on the restroom door, retrieve Ashley, return the keys, and exit to unlock the achievement.
(This one can be tricky—it took players hours to figure out!)
- “No Witnesses”

Left no witnesses.
- After sacrificing the campers, chase a child into a car.
- Break the car window with a rock.
- Interact with the child to eliminate them and secure the achievement.
- “Happy End!”

The ending you deserve.
- Following the camper sacrifice and dealing with the child, Ashley will talk to you.
- When police sirens sound and a portal appears, do not enter the portal.
- Wait for a few seconds to unlock this hidden ending achievement.
- “Warden Wins”
Got caught.
- This achievement is from Episode 1 and was added in the Episode 3A update.
- Playing as Ashley in the cultist’s apartment, clean the blood until the Warden knocks on the door.
- Immediately head to the balcony door.
- This leads to an alternate ending and unlocks the achievement.
