The archive is filed under cs_, but the map file is de_chlodnia and it plays as a defusal map. It is built around a three-storey public building with a yellow facade and long rows of windows: a paved forecourt with flagpoles behind a stone-and-mesh fence, a lawn with trees around the back, and a gable wall covered in graffiti with two painted figures. Interior frames walk corridors lined with display cases and notice boards, a hall with a mosaic wall and benches, and an entrance lobby carrying the map name over the doors. Every frame is bright daylight under a blue sky.

The grounds spread over 6567 × 5817 × 1026 units, a footprint beyond de_dust, and carry 10,647 faces with 79 textures. Twenty spawns per side seat forty players. Instead of hostages the map holds three bomb sites, and both teams get buy zones. Nine breakable objects, seven illusionary volumes, three ambient sounds and a ladder fill out the building. Besides the map the archive ships its own chlodnia.wad texture pack.
