A single grass field walled in by concrete on one side and a tall wooden palisade on the other, with big wooden crates set out across the lawn as cover. One frame stands at ground level between two of them, with a palm frond leaning into the shot; a second looks down from above and shows how the crates are arranged in loose rows and short walls, leaving lanes across the grass. In the third the sun sits low behind heavy grey cloud and lights the fence from the side. Despite the cs_ prefix there is no building, no hostage and nothing to rescue: the field is the whole map.

The field measures 2624 × 1184 × 832 units and is built from only 358 faces and 10 textures, one of them embedded, which puts it far below de_dust2 (5,383 faces, 44 textures) and about as light as Half-Life geometry gets. Sixteen spawns per side seat 32 players, and buy zones are absent, so the engine places them at the spawns. There are no hostages and no rescue zones; weapons come off the floor instead, six MP5 Navy laid out around the field. Beyond seven sprite props and three sprites there is nothing to operate: no doors, no ladders, no breakable objects. The sky is grnplsnt and the archive holds the .bsp alone.
