Tau Ceti IV keeps four zones
Perimeter holds Hauler, the North Relay, Station, Overflow, and the South Relay. Dire Marsh sits in the swamp, from the Algae Ponds to the East and West Gates.
Outpost is the UESC facility at the airfield and Pinwheel Base. Cryo Archive is the ship: Biostock, the Panopticon, and Preservation. Exfils, locked rooms, and DCON terminals stay on each pause map.
Games
Prove you know Marathon. 170 named pins sit on this plate. Name a still, drop a pin on a place, or read a blurb. Repeated marks — stars, chests, the same name twice — stay out of the round.
