Body message

The body message is a long-running key element of the INFRA ARG, the first ever element of it that was discovered.
It has strong ties to the Bunker computer code and Wasteland notes.

Finale has done a lot of work on cracking this part of the ARG, for further reference please see his Steam guide created for this.
It's located in Isle2 and is a code written on the sheet which covers an unknown corpse in a side building.

Cracking the code

The code sequence for the body message is:

B1 C3 F1 B2 F2 C4 E4 G3 B2 G1 F4 B4 B2 G1 G2

Which translates to:

I will show the (F2) (C4) ?O... tell the right answer under ground to the right person.

The entire body message revolves around a series of letter-number references, which correspond to words that have been found in INFRA maps and textures. The following is a table containing all of the current keys and their corresponding words.

Clues

 

The hint

The hint Zuntti gave us for this "code segment" is "BUN_BREAKER_CEN_CONTROL_VI_OFFICE_RE_SNW".
There are four clues here, each representing a location or map in INFRA.

"Bunker breaker, central control (room) (the control room in Central), Villa office, Reactor SNW (area)?"

Bunker breaker

This clue refers to the breakers outside the Bunker, in the Servicetunnel map. This has been confirmed by Zuntti's screenshot.
Possibilities here are the signs on the breakers themselves which have small text as follows:

(Breaker 1) Main text: TGD-SBC-4, small text: BR4 TGDNUM PO7 TGD1
(Breaker 2) Main text: HW-SBC-2, small text: BR4 HWNUM+1 O34 C87 EA2 N6

TGD could mean Three Gorges Dam, and HW is probably Hammer Valley Water Dam. Both breaker small texts have a "NUM" on them, prefixed by their name, with 1 being added to HWNUM.
Another possibility was the book with the bunker codes, however some codes are completely illegible and decoding with several bases does not result in anything of note.

Central control

This clue refers to the control room in Central, where there are a few code possibilities.

Morse

The first one is the Central projector morse, which does not produce a code but a message/clue about "the right person".

Pegboard

The second one is the pegboard, which has two possibilities of its own: the pegs, the markers behind, and the unrelated notes stuck to the pegboard.

Pegs

These are the pegboard pegs, transcribed.
E means empty, P means peg and M means peg with marker.

Notes
Note 1

 

RT 34968 BG 125675567
HK 675756 B1 = I KK 32
32123 B2 = the 1231324
123 B3 = in 364363463
B4 = TO 423424234 423
54353 C3 = 1(KKKKKKKK)
= WRONG 234 OIYUIO
W1I1L1L1 = RIGHT tr45
YTIT NOT B5675675567
Maybe YTWE 91267867

Removing the clutter, we can solve B1, B2, B3, B4, and C3:

B1 = I
B2 = the
B3 = in
B4 = TO
C3 = WILL

Note 3

 

Villa office

This clue refers to the office in the Villa map. Some small writing was found on 2 up-side-down boxes in the villa office. These boxes have green stamps on them and their models are named props_dam/hartman_woodbox_001 and props_dam/hartman_woodbox_002. Could these be clues referring to Alex Hartman after the murder of Jeff Walter? Or maybe Albert Hartman?

!!! NEEDS IN-GAME SCREENSHOTS !!!

   

The writing on the first wooden box says " 1 M 22 2Y" and the writing on the second box says "12 2 BT 13 17".

The Green stamp on the box looks like Zunttis Logo.

   

Reactor SNW

This clue refers to the secret SNW area of the Reactor map. The Reactor lights code is present here but does not seem to be connected to the body message, so it should be ignored.
