After some event, you wake up on the ground, get on your feet, and see Mr. Peterson's home.
The night sky and atmosphere feel off, just like in the demo.
You walk over to Mr. Peterson's house and see a key for the basement door on the floor.
You unlock the basement door and see some sort of black void behind it.
After a few seconds, the Guest sneaks up behind the player and pushes the player into the void.
