Halls of Dusk

First-person exploration

Halls of Dusk is a first-person exploration game for PC, set in Lammas House, an ordinary-looking home with impossible, non-Euclidean rooms. Harrow & Finch have sent you to investigate it. You walk between rooms, search for clues and try to leave through the door you entered.

The house doesn’t follow a normal floor plan. Walking north, east, south and west can take you through a fourth door that doesn’t lead back to where you started. Every room exists, and open doors stay open. From one room, you can look through two doorways into other rooms that can’t both fit in the space.
