The community has done a tremendous job collecting all the clues, solutions, and open theories.
See it in all its glory in the ARG MASTER TRACKER
Warning: lots of spoilers in the Master Tracker, so only head there if you're stuck!
Community events like the ARG is just one way we wanted to bring Theorists together. We encourage you to join Discord because it’s an amazing way to chat live with other Theorists and even make a friend or two. Please don’t be shy!
