Despite the cs_ prefix this is a bare fighting arena: a single dark hall whose entire floor stands under murky green water, with rust-stained concrete walls, scattered stone blocks and a wooden crate for cover, all beneath a sooty rock ceiling. There is no sky at all — the map is fully enclosed, lit by a few dim spots, and the title card on the source screenshot styles it BloodStrike3-New Style.

The box measures 1824 × 1824 × 384 units and keeps geometry minimal: 847 faces and just 7 textures. Ten spawn points per side admit up to 20 players, but the parser finds no hostages, no bomb sites and no rescue zones — only the flooded floor as a single water volume and one ambient sound. Buy zones are not drawn either, so the engine places them at the spawns.
