The Glass Perimeter

Dam watch

The Glass Perimeter is a short PC game about keeping watch on a vast arch dam. You monitor pressure terminals and prevent the valves from blowing while moving between catwalks, the watchman’s booth and a switch room where electrical arcs crack between cabinets.

Sudden sounds and flashes freeze the frame, ring your ears and raise stress. A damper visor blocks the glare and quiets the world, but its glass fogs and its air runs out. The booth offers shelter from the noise, though its silence also presses on you. In the switch room, you need to time your passage between flashes or use the visor’s limited air.
