Snow falls the whole time over a modern city block, and the textures are far sharper than the engine usually gets: a stone faced apartment building with tall shuttered windows and a wrought iron balcony stands over a concrete yard, with slab sided office blocks around it and a bare tree against a wall. A weathered white container sits on the snow covered concrete, street lamps burning against a dark sky. Another frame faces a white corrugated warehouse with a rusted double door under a lamp and graffiti sprayed on the panelling. A third is below ground, where white containers and grey timber crates are stacked beside old machinery on a tiled floor, with a roadway running past.

The map is 4896 × 3744 × 1472 units. Fifteen spawns per side seat 30 players. Four hostages and one rescue zone define the round, there are no bomb sites, and the map carries no buy zones of its own, so the engine puts buying at the spawns. Geometry is heavy at 9,287 faces, roughly triple the 3,206 of the stock cs_assault, but it runs on only 35 textures, all of them embedded in the .bsp. Nineteen non solid brushes and fourteen animated sprites do the scenery, with seven ladders, four breakable objects and four ambient sound sources. The sky is the london skybox and snow falls as a weather effect. The archive installs fourteen models and four sounds of its own.
