Marathon C.03

Marathon C.03 is a prestige-rarity key tied to the Cryo Archive zone and associated with the UESC data cache network aboard the Marathon ship, and carries a confirmed assessed value of 2,000 credits upon extraction. As the third key in the Marathon C-series, C.03 is one of the entries confirmed to have been discovered by players in the field, part of the community-driven ARG that is progressively unlocking details about the Cryo Archive's lore and purpose. The key's metadata includes location: uesc.marathon, zone: cryo.archive, and status: access offline, await decryption, pointing to its role in a larger sequential decryption effort tied to the ship's restricted data systems. C.03 was among the early confirmed C-series keys found, alongside C.01, C.04, and C.06, as players worked through the ARG's first stages using terminals on Perimeter and Dire Marsh. Whether C.03 unlocks a specific data cache or serves a function within the broader Cryo Archive ARG sequence remains part of the ongoing mystery.
