Misc code - WAKEUPJOHN
Sometime after the translation for the symbols were discovered. Users started to attempt to brute force possible codes. This led to a user finding out that if someone entered the symbols to say "Wakeupjohn", a new video would be unlocked of a glitch, with subtitles that were related to the Anniversary Campaign Trailer. This was promptly locked and removed from the code pool. This suggesting it was not meant to be found.
