Central Executive in the hub, the Maze in Research, the Panopticon in Containment
The Oldest House sits on the Bureau’s own blueprints: Executive around Central Executive, Dead Letters, and the Director’s office; Research through Parapsychology, the Ashtray Maze, and the Hedron Chamber; Maintenance around the NSC plant and Black Rock Quarry; Containment with the Panopticon and the Ordinary AWE; Investigations for Bright Falls and the other altered worlds; then the Foundation caves under the rock and Quarry Site Beta off that stone.
Rooms, chests, collectibles, and control points stay on. Hidden rooms and the extra spots start hidden so the hub and the Maze stay readable. Open them when you are hunting a restroom cache or a mold sample. The Maps tab swaps the wing.
Games
Prove you know Control. 158 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.
