This is an explorable fan reconstruction, built at human scale. The show establishes 144 numbered levels, the great staircase and the principal departments. No complete, dimensioned, room-by-room production blueprint was available in the references reviewed.
The 10 m level spacing, 36 m central shaft diameter, service routes and room plans are reconstruction estimates. Unseen floors use furnished layouts fitted to the silo. Department locations without reliable television confirmation are marked in the directory.
The connected Level 1 cafeteria, sheriff’s station, preparation area, pressure doors and ramp lead to an explorable barren surface. Clean the exterior camera with Use / E; its live view feeds the wall screens. The generator hall lies below Level 144. The cavern and digging machine follow published production references. The mines and hidden passage contain inferred details.
The opening recreates Holston’s cleaning with animated 3D figures on the cafeteria’s exterior feed. Allison is already on the hill; Holston cleans, removes his helmet and comes to rest beside her. The book and directory introduction are original game framing. Spoilers are present.
The three supplied character models are retained. Twenty additional Silo 18 character models have individual costume and silhouette treatments informed by Apple’s production stills; their faces are approximations, not scans of the actors. Seventeen join the playable cast. Holston and Allison appear in the cleaning, and George’s model is retained as a historical character rather than placed among the living residents. The ensemble uses the first two seasons; characters from Silo 17 and later timelines are not placed in Silo 18.
The bazaar’s placement on Level 100 and most residents’ exact stations are inferred. The population supports exploration rather than a complete simulation of the show’s chronology. Opening completion is remembered on this device; Replay starts it again.
