Fallout 4 giveaway! But this time it has a twist!

I SOLVED IT!!!! THE WHOLE PROCESS IS BELLOW! TOOK 2 HOURS BUT I FINALLY FIGURED OUT HOW TO DO THE HARD PART! BELLOW IS THE WHOLE WRITING I DID WHILE FIGURING OUT HOW IT'S DONE!

I always lose luck-based giveaways, but this I can do! I’m a huge fan of a tv show that involves decryption (I’m obsessed with it), so this should be easy!

Note: I just wrote this after finishing the puzzle and that was not easy at all.

(I’m going to write this on word because this looks bloody huge, and I’m not going to lose my work to my shitty internet connection…) here we go! (I swear if someone already solved it by the time I’m finished writing this I will … ummm… do something that is not very embarrassing but definitely unpleasant.)

The puzzle stars with some numerical code. It turns into

‘’NUMBERS TO LETTERS IS AN EASY START. I'M JUST GOING TO GIVE YOU A GUIDE. FOR THE NEXT ONE, WRITE THE ALPHABET 2 TIMES. ONE FORWARDS, ONE BACKWARDS. THATS CALLED ATBASH.’’

And now it tells me to use atbash on the next code. It turns into

‘’ WcDl684 what could it mean?’’

So now we have WcDl684… which could be anything, but I tried pasting it at the end of an Imgur link and guess what

http://imgur.com/WcDl684

It has the following letters in black:

WKH GXFN ZLWK D UHG IDFH LV ZKDW BRX'UH ORRNLQJ IRU

So I tried various decryption methods, until 3 letters back did it.

THE DUCK WITH A RED FACE IS WHAT YOU'RE LOOKING FOR

So I searched it in google, and it turns out Muscovy ducks have red faces!

Now the binary translates into this link:

https://en.wikipedia.org/wiki/Vigen%C3%A8re_cipher

Vigenere cipher, we probably need to use it on the next one

So now we have nLqsCAv

Looks like an imgur link again, but it leads me to an error page.

So I tried using ‘’muscovy’’ from the last 2 codes as a vigenere key as in the article, which encodes every letter with a different letter to make a message, and it leads me to

http://imgur.com/bRyqOFx

Now that’s an actual picture!

It says the first letter in the third word….

Now there’s a lot of small messages bellow… but they don’t make sense yet so I’m decoding them first

THERE ARE 7 UNIVERSES

Got come coal for the machine

He said ‘’Oh snap!’’ and the crowd laughed

CRAP THE IGLOO IS MELTING!

ITS COMPLETELY EMPTY! WHAT DO WE DO?

I said ‘’DO NOT PRESS IT’’

THE RED BILLED HORSE IS TOTALLY REAL!

(Works with atbash)

The sentences don’t seem to relate…. The story doesn’t make any sense….

Oh yeah, use the first letter of the third word…. Maybe on each line?

Turns into

7coIEDB

BINGO! Another Imgur link.

http://imgur.com/7coIEDB

(the corner seems to say /u/ over and over, so I’m going to guess this are users…)

Found the first, second and third accounts on this thread!

NOTE: i just remove the link here since the bot erases my post if i link another subreddit. you can find it on /u/codepart1 's only post

1 code per account, they’re all using atbash cipher

THIS IS PART

OF A VERY

LONG KEY

So now the third account gave us a picture after its code that says that the last 3 are not names but keys.

So we take them, put them in order (3-4-5 makes enough sense if the first 3 were in order.) and turn the numbers into letters (it seems the red lines were separating the numbers)

6-7-3 goes to FGC

8-7-7-7 goes to HGGG

4-5 goes to DE

So that gives us the keys

5 UXYFGC

3 HYUHGGG

4 HAHDEB

We put them in order

HYUHGGG

HAHDEB

UXYFGC

And then use them as keys for the words on the picture.

AYEL OZ

HLS RV GHIS

SLSW SKMPGTT

Each with their respective key turns into

TAKE IT

ALL OR FAIL

YOUR MISSION

We combine both parts

THIS IS PART OF A VERY LONG KEY TAKE IT ALL OR FAIL YOUR MISSION

Now OP told us to use what we had on CMVBKFLUSUOMGGOTKWIOGTZEGVUWLNBSUUXLDCMKTWY… everyone’s stuck at this part right now but the code adobe said that it was a long key..

If we use the whole sentence as a vigenere key then it translates to

JFNJCNWUBBAHGLKCMLUBAJVGNVKSDUBHJGGGDUBMFCH

Which still doesn’t make sense.

But the final part is next. Using atbash or other alphabetical ciphers doesn’t turn it into anything that makes sense so I’m going to use the weird code adobe on it…

HTH OKAWFMZ MHJP SV TPLF, I QJVR D RAG NIL LUJKV QFXQ, DLLFHBG GDCT THVAWN DQ LFNOBO OZKYKVCCSN ZU IKYBF. BGSU IBWG. V'I APJNN ZZ DGXW SPU XIK GCSFJ: ''Q'' BUM LKTFY. BXXQ BBJ JQCG UIV VSLJ ZX VTTM DOMZ UA ORW FIEL KKRRRQ CQKQYN IBRPT SBBU I QADD VAWX ZOD. BUBY VMFE, ZVD'XK GOGPEY VONWR.

Put they key in and BOOOOOOOM IT MAKES SENSE!

YOU FINALLY MADE IT HERE, I HOPE I HID THE CODES WELL, BECAUSE THIS SHOULD BE ALMOST IMPOSSIBLE TO CHEAT. WELL DONE. I'M GOING TO TELL YOU ONE THING: ''W'' AND FENCE. ALSO USE WHAT YOU USED ON THIS CODE ON THE CODE BELLOW BEFORE DOING WHAT I JUST TOLD YOU. GOOD LUCK, YOU'RE ALMOST THERE.

W and Fence? A quick google search tells me it’s a railway fence cipher!

https://en.wikipedia.org/wiki/Rail_fence_cipher

it explains that we have to select letters in a fence shape… that’s kind of easy actually

so we use the key JFNJCNWUBBAHGLKCMLUBAJVGNVKSDUBHJGGGDUBMFCH on all the text as then end of the code says it turns into…

E Y X H I J a

H G G I H G c

I B Q H K F f

Which says EGQIIGf when you take out the specific letters as a w shaped fence…..

It’s yet another imgur link!

http://imgur.com/EGQIIGf

now this one doesn’t have any clues. I’ll see what I can do

UIFKG V V h P XQBR is the code in the pic

Alright found it. If you look closely, there is some very dark text on the black part of the picture, so copy the picture and place it on paint, you can bucket fill the black part with white and it will show you the hidden words ‘’I like throwbacks to the start, weird name isn’t it?’’

It may be referring to Muscovy on the start. If I use Muscovy it turns into

IONIS A X v V FONW

But that doesn’t make sense, nor can be decrypted or shit…. If it’s a throwback to the start it has to do with ‘’muscovy’’

GOT IT! Searched Muscovy on Wikipedia, and got the weird scientific name ‘’cairina moschata’’, which can decode the code properly!

SIXTY I V v B FOUR

That one has 2 clear words! Maybe another imgur link?

60IVvB4, yup.

http://imgur.com/60IVvB4

‘’what do I want’’ and ‘’ HOYRFUMX! I HTZF GTW ACWPTYE XPGMTLE JZI. SHZ WZY O ZKJE NZDS HK FLWZINY FZFF!’’

YES IT DECODES INTO THE END MESSAGE IF YOU PUT FALLOUT AS KEY FOR WHAT YOU WANTED!

‘’ CONGRATS! I WILL NOW PRIVATE MESSAGE YOU. YOU WON A FREE COPY OF FALLOUT FOUR!’’

Damn nice! This was super fun (and stressing) to solve, OP! There’s the solution! Is this the part where you PM me?
