Marathon C.02

Marathon C.02 is a prestige-rarity key item associated with the Cryo Archive zone and the UESC Marathon ship, serving as the second entry in the Marathon C-series of ARG-linked access credentials. Its item metadata echoes the other C-series keys: location referencing the UESC Marathon, zone referencing cryo.archive, and a status of access offline awaiting decryption. The community has recovered multiple C-series keys through in-game drops, with C.02 representing a step in a sequential unlock sequence that Bungie has embedded into the Cryo Archive narrative. What specific area or system C.02 unlocks aboard the Marathon ship remains undisclosed, as the ARG puzzle connecting these keys to actionable in-game outcomes is still being deciphered by the player base. Its prestige rarity and carry value make it a highly sought-after extraction item even for runners not actively engaged with the ARG.
