Players of Marathon have reached the final stage to unlock the Cryo Archive map, requiring 500 million UESC robot kills and a symbol-matching puzzle. Progress stands at about 330.5 million kills, or 66.1 percent complete. At the current rate, the map could become playable next week.
The unlock process for Marathon's Cryo Archive, the game's fourth and final map, now hinges on two tasks: eliminating 500 million UESC robots in PvE encounters and completing a symbol match-game puzzle measuring 25 by 42 tiles. Players must match all tiles within three minutes, with the grid shrinking incrementally for every one million robots killed, making it a collaborative effort between puzzle-solvers and robot-hunters alike. A fan-made API website tracks the kill count, which has accumulated steadily during puzzle-solving and regular gameplay, avoiding wasted time. As of the latest update, 330.5 million UESC robots have been destroyed, putting progress at 66.1 percent. Without developer intervention, this pace suggests Cryo Archive will unlock next week, possibly not before the weekend. A post on the Marathon Discord server hints at exponential progress acceleration, where each kill near the target might count for more than one, potentially speeding up the final stretch. Recent developments include teaser trailers and in-game Cryo Archive challenges, with an experimental duo queue available for players to rack up kills efficiently.
