If there was any doubt that Marathon would be Bungie's new canvas for community puzzles and ARGs, let it go, because the community has already stumbled into a doozy. Terminals linked to Marathon (the ship) on Perimeter have suddenly awoken, and they're pointing toward a spooky audio log seemingly left by Durandal, the rampant AI from the original Marathon series.
These terminals, as far as I can tell so far, are sharing scraps of info about the Cryo Archive, the upcoming fourth map that's supposedly similar to a Destiny raid. As shared by Reddit user Ok_Fold_1268 (and others), terminals that were previously inoperable on certain compounds in Perimeter now display a map marker that points toward a second terminal.
