Bunker computer code

This page is about the infamous bunker computer code, the code found on the computer in the side room in Bunker.

This is an exact transcription of the text on the computer, extracted directly from the game files.

Table of words

The first section is a table of words. If you read the first letters of each word starting for the top left word and going down column by column you get UKURISGODGTRUTHISALBLBDOORTGMWMQPMMMMCSW Cleaning it up reveals the following: UKUR IS GOD. G TRUTH IS ALB. LB DOOR TGMW, MQPMMMMCSW.

Notes:

• UKUR IS GOD is a reference to ancient Mesopotamian god/spirit named Ukur the god of underworld.
• Truth is alb(ert)?

First reference table decoded

The second section is a smaller table of "relational codes" which refer to the same codes as the body message. The dotted number after the word codes refer to the index of the letter in the word specified.

The word for A3 is currently confirmed to be "to", of which the second letter is clearly "o" , although the code requires it to be C (A3.2=C). A possible answer to this is that the 3rd word of the Office monitor code is "accident", of which the second letter is "C"; also, the Tunnel of Water Trees Book Code has C.2 as one of its codes.

Using the codes from the body message, we get this text:

C3.1 = W F1.2 = H F4.1 = A B2.1 = T A3.2 = C E4.2 = O F4.2 = N G2.6 = N G3.2 = E A3.2 = C
G1.5 = T F1.1 = S F4.1 = A G3.3 = L G3.4 = L B2.1 = T G1.4 = H B2.3 = E G2.4 = S H4.5 = E

This results in the ARG-related question 🔑 WHATCONNECTSALLTHESE, which is also used as a key in the reactor lights code.

Second reference table decoded

The third section is a grid-reference to the words in the first section (the table of words). The first number refers to the horizontal index and the second to the vertical index.

The references to the words are mostly unique. The only exception is that "Tunnel" (2.4, emphasized in the table below) is referenced twice, while "Open" (3.4) has no reference.

Using the references we get this text:

UGU Underground World God Mines               Inventor AH Homeless People Machine
Mask Man Tunnel Guard Knowledge               Body Message Question Show Truth
Raven Research Institute Lead Organization    Green Death Blue Right Meaning
Water Trees Diving Suit Legend                City Tunnel Sewer Us Omitted

We can translate this a bit:

UGU (is) the underground world god (of the) mines.
Inventor (is) Andrew Herts, Homeless People (made) the machine.
Mask(ed) Man (in the) tunnel guard(s) knowledge
Body Message Question Show(s) truth
Water Trees Diving Suit Legend (???)
City, tunnel, sewer, us: omitted.

This code is heavily connected to the Body message through its use of the similar letter-number codes.

Zuntti reference table

This is a coded message from Zuntti, when decoded it gives the word "maybe".

How to decode:
Write each NUM down AMOUNT times: 01101101 01100001 01111001 01100010 01100101
Decode from binary using ASCII: maybe
