Tunnel Maze
First, you must navigate through a tunnel maze. The tunnel is covered in glass, so you must move as slowly as possible to avoid getting hurt. To get out of the tunnel as quickly as possible, go right at the first fork, then left, then left again, then right. You will exit the tunnel and end up in the next section of the trial.
Electric Maze
The next part of the trial forces you to work your way through a grid of electrified squares. You will be approaching the grid from the south, so enter the grid at the second square from the right. Move up two squares, then move right one square, then move up three squares to exit the grid.
"Coward!" Trophy
To earn the game's "Coward!" trophy, use the door next to the electric grid when you arrive there. You will quit the trial and abandon one of the clues to find your son.
"Electrified" Trophy
Complete both sections the trial to earn the "Electrified" trophy. Additionally, you will receive another clue about the location of your son from the killer.
