Okay, so.
There was this ARG connected to a game called Oxenfree back in 2016.
The clues led the team to a final destination:
Bainbridge island, WA
The real-life team went there on JUNE 11
IT JUST HAPPENS to be in the same area as THE MISSILE LAUNCH / SKUNK BAY
Oxenfree is HEAVY with decoding messages covered-up military operation regarding the supernatural and atomic submarines, hidden meanings and occult symbolism and with a team-ran ARG that was very well thought out AND got people thinking in the way that we'd need on this board??
Coinkidink?
