DISCLAIMER:
This is presumably from the launch version of the game.
A couple of the bolded names were removed or changed, expect about 16 characters and 48 ARMS.
NOTICE:
I actually wasn't the first one to find this–
Rather, the first one to share this. For an in-depth summary of this find, I recommend you to take a look at this video others worked at before I submitted this list, not realizing its contributors technically found this before me and have put more work into this. My bad! https://www.youtube.com/watch?v=jkJ4NqN7hTU (I really should've joined the Discord sooner to find out about a"leak livestream"coming soon, but this should do it for future media coverage I expected, but didn't take seriously. Honor whom honor is due!)
