  • Chapter 1: Bad Decision
  • Evidence: 8
  • Bodies: 3
  • Cassettes: 3 (Venus by Chieshin, Epitaph of a Good Friend, Classical Music Collection)


Bad Decision: First Secret Location


Go up the apartment stairs until you see two windows. Exit through the unobstructed window on the left.


Once outside the window, follow the railing to the left to reach the opposite side. You will discover a Secret and some cash.


Bad Decision: Second Secret and First Cassette Location

Head back inside the apartment and take the stairs to the floor above where you found the two windows.

Continue inside until you spot a window blocked by wooden planks directly across from the bathroom.


Break the planks, head outside, and descend the stairs.

Enter the hidden room below to collect valuable items and the "Lucky Key" before heading back out.


Once outside, you can either jump from the stairs or lower the ladder next to them to descend.

Either way works as long as you get inside the chain-link fence, but lowering the ladder is recommended for easier navigation later.


Go through the fence and follow the path to the end until you see an iron door.

Go inside to find the second Secret and the "Venus by Chieshin" cassette.


Bad Decision: Third Secret, Second & Third Cassette Locations

Climb back up the ladder, and you will see a makeshift lift (elevator) on the opposite side.

Take the lift down by pressing the button. You will find a room blocked by wooden planks.


Break the planks and enter to discover a Secret and the "Epitaph of a Good Friend" cassette.


Head back inside the apartment. While cleaning, look at the ceiling of the far room to find a white hatch leading to the attic.

Open the hatch and climb into the attic to find the "Classical Music Collection" cassette.
