Backrooms: Last Signal

Explore a yellow-wallpaper Backrooms maze in first-person 3D. Recover three fuses and return to the emergency exit. A shadow follows noise: break sight around corners and walk quietly.

Touch: left pad to move, drag the right side to look, E to interact. PC: WASD, mouse or arrow keys, Shift to sprint. Your exploration map remembers visited corridors.

Choose Level 0 or Level 1 from the menu. Level 1 adds a concrete warehouse with fog, puddles, supply crates and failing lamps. Touch look now follows your swipe: up looks up, down looks down.

Explore a bounded interpretation of Level 356η, with brick corridors, marble floors and void skylights. Close your eyes with B / Q or the on-screen button to evade forbidden numerals, restore the signals and escape.

Explore a bounded Level 336η inspired twilight town. Leave black shadows to recover from corruption, avoid the familiar-looking lure and restore the supplies exit with three fuses.

Explore a bounded Level 220η inspired Arctic ski resort. Warm up at lodges, survive blizzards, ride the lift across snowfields and restore the exit with three fuses. This is a finite walking exploration adaptation; ski descent and travel to other levels are omitted.

Find three wanderer diaries in each level. Read with E and revisit them from the exploration journal. Explore a bounded Wikidot Level 11.3 Red Light District adaptation: use your mask and clean-air stations, evade Servants and restore the bridge gate with three fuses.

Explore Level 4η Playroom and Level 12η Scopophobia. Restore the ladder with three fuses in the playroom, or sleep at the school rest mat to escape. Both areas have three diaries and no pursuer.

Added Levels 2, 3 and 9: maintenance tunnels with heat bursts, brick electrical halls with live floor zones, and midnight suburbs with rolling fog and faster pursuit. Each has three diaries and a three-fuse return-to-exit objective. These are bounded adaptations with custom game hazards and escape rules.

Added Level 37, the Poolrooms: white-tiled halls, pillars and gently rippling turquoise water. Wade without pursuers or damage, read three original diaries, collect three fuses and return to the starting green exit. A bounded shallow-water adaptation; no swimming, diving or travel to other levels.

Added Level 1993, an original bounded Boiler Sector interpretation. Evade the Rattler, avoid drawing it with running or your flashlight, recover ringing under turquoise emergency lights, and survive faster pursuit during periodic blackouts. Three new diaries and a three-fuse escape. Other entities and cross-level travel are omitted.
