- Interact with the closet and choose “Do you have any symptoms?”
- “Why are you bleeding?”
- “Do you have any proof that you are sick?”

- “You’re not telling the whole truth about your family.”
- Choosing “Okay, I’ll try” and “Tell me what happened” can add extra time.
- Leave the conversation and open the drawer to your immediate right. Take the Pressure Gauge.
- Look under the bed and take the Empty Medicine Bottle (Only appears if you gave him the med kit).
- Enter the bathroom and take the Faded Photo.
- Go back to the closet and choose “I found an empty medicine bottle”, as well as “I found a photo of your family. You’re not in it.”

- Choose “draw without thinking.”
You have survived until the beginning of the seventh day.
Story related. This will unlock after waking up on day 7.
Day 7
You helped the professor guess the nature of the infection.
As soon as you leave your room, knock on room 311 and answer his questions. I’m not sure if the choices matter, but these are what I chose for the achievement:
- “They depend on personality and experiences.”
- “Water.”
- “People turn into monsters!”
You’ve returned water to the hotel.

When you arrive on the roof to talk with the priest, your path can split. “Shepard’s Method” and “Dark Embrace” can’t be earned in the same playthrough.
- “I came here to talk.”

- “How do you know that God is speaking to you?”
- “You taught me yourself that you can’t trust anyone.”
- “Isn’t it the devil who tells what people want to hear?”
- “Forgive yourself and others.”
You let the darkness in and killed the priest.
This is the same encounter as the achievement above.
- “Robin, are you okay?”
- “Release her first.”
- It’s just an infection. It can be cured!”
- “She didn’t do anything wrong.”
- “I’ll stay with you and help if you let her go.”
- KILL HIM
ENDINGS SPOILERS
READ AT YOUR OWN DISCRETION
You decided to return to Robin and leave the shadow behind.
After dealing with the priest, you’ll go through an underwater section with Voice. Eventually, it’ll just be you and her in a vast ocean, with the prompt “Accept her”. Do not click this prompt. Turn around and run towards the light. Voice will try to stop you multiple times. Keep ignoring her and heading towards the light.
You accepted the shadow’s invitation and were transformed.
Pretty much the same as above, but this time choose “Accept her”.
