Upgrading the WW on SOE!

So recently there has been a lot of debate/controversy about the new audio clip found, I don't know too much about it but just wanted to make a page for people who are trying to upgrade this Wonder Weapon as I am. We really need to figure out how to upgrade this thing, if i'm right in saying that there is another buildable that we haven't obtained yet then perhaps upgrading this weapon could reveal what it is. Following the previous step, kills in front of the PaP, would lead me and many others to believe that this upgraded weapon is in fact not buildable, which would leave a lot of speculation as to what it could in fact be. But that would be off topic, anyway, if you find/figure out any new information on this, please do feel free to leave it below! ,Thanks for reading!
