The Creepy Syndrome (UP)

This achievement is for unlocking one of the two bad endings for the session "Lord of the Road".

I encourage people to try playing through on their own before using a guide.

Here are the steps to complete the achievement (spoilers ahead).

-Find the fuse. From the road, go south one screen and then go left. Follow this path until you find a screen with an altar. The fuse will be here as well. Pick it up.
-Backtrack to the screen just south of the car (there will be a house here). Go right at this screen and continue following it until you find a screen with a generator.
-Use the fuse on the generator.
-Return to the central hub again (with the house) and go south this time.
-The generator will have activated a ladder in the well.
-Go down the well
-Read book and watch cutscene.
-Exit well and head north until you reach the road. Your car will be gone.
-Grab the key on this screen (near upper right of screen)
-Go south one screen, then turn left (like you were going to the altar).
-There will be a house along this path. Use the key to enter.
-On the second floor, there will be another key. Pick it up.
-Once done here, head back to the main hub screen, with the house.
-Use key to enter this house.
-Grab the dagger first then talk to Martha.
-When give an option, choose to sacrifice Martha.
-Try to leave the house.
