A research building in a city at night. Outside, a flight of pale stone steps rises between two carved columns to the entrance, a helipad marking is painted on the plaza beside it, a helicopter hangs in the air just off the parapet, and behind it stands a skyline of towers with lit windows. Inside, the map is all laboratory: white tiled floors and grey walls, open plan rooms with desks, computer monitors and office chairs, steel cabinets, benches with racks of glass flasks and blue vials, wide observation windows, a lit alcove displaying a figure, and a long blue grey corridor with rounded pillars and strip lights running to a door at the far end.

The map is 3312 × 2928 × 1088 map units, a compact plot roughly two thirds the ground area of de_dust2 at 4864 × 5600. Sixteen spawns per side seat 32 players, which is a lot for that footprint. There are no bomb sites; four hostages and one rescue zone set the objective, and the map has no buy zones of its own, so the engine places buying at the spawns. Geometry is light at 5,981 faces on 114 textures, all embedded in the .bsp, close to de_dust2 with its 5,383 faces. The entity list runs to 56 non solid detail brushes and 24 animated sprite props, which is where the lab equipment comes from, plus eight doors, five pushable objects, three ambient sound sources and one ladder. The archive installs eight models of its own and an ambience sound.
