A three storey school building of standard prefab design: pale yellow plaster walls, red panels between the window bands, a ribbed metal roof. One frame looks down into the inner courtyard, dark asphalt with a covered porch and a wide flight of steps at the main entrance. The rest are interiors, and that is where the detail sits: long corridors with speckled terrazzo floors laid in a coloured border, glazed classroom doors with small red plates beside them, wall boards carrying newspapers and posters, fluorescent fixtures on the ceiling. Another frame catches a stairwell with green nosings on the steps and daylight coming through the window, and one more looks past a doorway into a gym. Sunlight lies across the corridor floors; the courtyard shot is overcast.

The map spans 3660 × 2651 × 791 units and is built from 11,516 faces and 90 textures, more than twice the geometry of de_dust2 (5,383 faces, 44 textures) in a smaller footprint. There are 32 spawns per side, so it seats 64 players. Three bomb sites are spread through the building, there are no hostages, and buy zones are set to auto, which means the engine places them at the spawns. The interior is heavily interactive: 135 breakable objects, 70 sprite props, 23 non solid decorations, 13 ambient sound emitters and three ladders. The skybox is the trainyard set. Besides the .bsp the archive installs 16 models, nine sounds, its own school.wad and two radar overviews.
