THE CORE CONCEPT
THRESHOLD weaponizes tonal dissonance. Players begin as an elite US military squad deployed by Async Technologies to "secure and contain" the Backrooms— confident, well-equipped, and in control. By the campaign's midpoint, that confidence is systematically destroyed.

PC (Steam/Epic), PlayStation 5, Xbox Series X|S

UNIQUE SELLING POINTS
Tonal Shift Gameplay
The only tactical shooter that becomes survival-horror while you play it.
The Backrooms as Military Sci-Fi
Corporate-military conspiracy, structured lore, and squad dynamics in the liminal space phenomenon.
Adaptive Squad AI
Teammates learn from your tactics, develop stress responses, and can psychologically break.
Reality-Bending Environments
Procedural environmental distortion using UE5 — corridors stretch, rooms rearrange.
True Cooperative Horror
Communication degrades as equipment fails, creating real isolation between players.
TARGET AUDIENCE

The liminal space / Backrooms community — fans of Kane Pixels, analog horror, liminal space photography.
