There is multiple locations throughout the game where a picture that resembles a word search puzzle can be found, This is the letter box.

The letter box code is solved by using the coordinates found on the three top rows. Each coordinate consists of an X, Y and three numbers.

Clues

Solution

The first number after the two letters indicates the number of the decoded letter in the current word. The second and the third number indicates the X and Y coordinates of the letter in the letter box and which number is used for which coordinate.

Example: XY134 is decoded as follows:

• (XY) Indicate that we use the second number for the X coordinate and third for the Y coordinate.
• (1) It's the first letter in the word.
• (3) It's third letter in the row.
• (4) It's on row G4.

Using all this we get the letter "R"

Using this method the following words can be decoded:

• G1 = Right
• G2 = Person (Missing letter "R")
• G3 = Tell

These words are used in the Body message.

"Song 4"

There appears to be the text "SONG4" on the board, it might refer to strange_hallway_004.wav. Looking at a spectrogram shows that there appears to be text on it, but it's hard to see what the text actually is.
