Exploration controls

Mouse — look around (click scene for pointer lock). W/A/S/D — navigate, Shift — sprint, Q/E — descend/ascend in drone mode, 1–6 — select stratum, M — toggle map, H — toggle panels, Esc — release pointer.

All tunnels connect to satellite chambers. Choose a destination on the minimap to teleport into the farthest sectors. The walking mode prevents passing through tunnel walls; switch to drone for unrestricted inspection.

Tip: enable Detail / Ultra only on a powerful GPU. Runtime builds geometry from a reproducible seed.
