Dialogue
"Ah, it's you. Local troubleshooter, huh? Yeah, I know about you. And you'd better learn one thing. You are not the only one. There are some other serious people out there, perhaps they could be even more skilled than you are. They're walking around, minding their own business, and from to time leave some stuff behind. And the thing is - I need those items. I know it's a hard find, but the reward won't disappoint you."

Riddle
Until April 19, 2019 there was a hidden riddle in the the quest title, dialogue and reward text.

Quest Description
Solving the riddle starts with the quest description, the first paragraph of the hex encoded text equating to  and the second one to. The first uncovered paragraph indicates the existence of Atbash ciphered text, the text  equating to , a clear substitution pattern. Using the aforementioned substitution pattern, we can take the second paragraph found in the quest description and translate it to, a clue which will become useful later along with the   and   texts.

Quest Reward Text
The first operation to be applied to the quest reward text seems obvious, either from the  (  if mirrored) text or from the nature of the text, it being a simple mirror of the whole text block. After a mirror, the paragraph  is revealed, making us understand that the number 13 should be eliminated in all further findings and that the base being used for them will be 64, instead of the human-used 10. Thus, after removing the already used text, removing the number 13 and decoding the text from Base64, we can observe the following text:  which indicates the use of the rot13 cipher. After another removal of our used text and a rot13 decryption we can observe the following lines:  coupled with   and   coupled with   which indicate the Affine and  Caesar ciphers respectively. After decyphering the Affine encoded text with the values  we obtain   and after decoding the Caesar encoded texts with a shift of 1 and 3 respectively we obtain after dealing with , both clues helping later.

Piecing Everything Together
To continue, we'll start with the remainder of our quest reward text:  a hex encoded string which we should not decrypt for now. The clue  shows that 2 (a number which looks similar to a swan) should be replaced by the number 5, doing so in our hex text and then finally decoding it, indicated by the   clue, giving us. Looking closely at the obtained string, we can observe the existence of the word  within it, the clue   telling us to remove it from the text. Doing so will finally reveal the text  which if attached to the   string obtained earlier, and being added onto a YouTube short link, as indicated by   revealing a YouTube video.

The Pastebin
Approximately a week after finding the first YouTube video, a Pastebin link surfaced in the video description. For ease in describing the decryption progress, we'll split the document in 4 sections, one for each paragraph and will start with the last one since it exposes the 1st step within the process.

Paragraph 4
The paragraph is Base64 encoded, but before decoding it, all characters that are found surrounded by a  character need to be deleted and the contents need to be set aside to form the string   which equates to   in hexadecimal. After the removal of the odd characters, the text  is revealed. We can note down the "file number" as the rest is just flavor text.

Paragraph 3
Using the former ROT47 clue we can solve this paragraph, applying a ROT47 decryption after a Base64 decode yielding the content we need, but slightly malformed. To clear this malformation every 22nd character in the original string needs to be removed (all of the characters being a 0), thus revealing. Like the last paragraph, we can ignore all text besides the file number.

Paragraph 2
After a reverse of this paragraph we can observe the string  (originally  ) is an outlier and will serve as a clue later, so we can remove it. The rest of the paragraph (still reversed) can simply be Base64 decoded to find. As with the former paragraphs, keep the file number and ignore the rest.

Paragraph 1
As with the former paragraphs we start with a simple Base64 decode. We can now take the  clue and use it as a substitute alphabet while ignoring the importat numbers, giving us the   string, which again, can be disregarded besides the file number.

Finale
Concatenating all file numbers together yields. If we group the characters and get their coresponding ASCII character, we obtain  which leads to the final YouTube video. The video has a few game keys in its description.The key are all activated and not available anymore.

Trivia
The second found video is reused into an official short movie called "Raid".
