A sealed indoor biosphere: white panelled walls, ribbed ceiling beams and sliding station doors around shallow pools of clear water. Palms and ferns grow from stone-edged planters in the middle of the flooded floor, hanging lamps light the side halls, and one hall opens to a glazed roof through which daylight falls in solid shafts. Another frame looks up a wide staircase of rough stone that carries water down into the pool below, with a bank of consoles at the top.

The layout runs 6208 × 5520 × 952 map units. Twelve spawn points per side let the map hold 24 players. There are no bomb sites: four hostages sit somewhere in the complex and a single rescue zone waits for them, and with no buy zones placed the engine puts them at the spawns itself. Geometry comes to 12,527 faces against 113 textures, all of them packed into the .bsp, which is well past cs_italy and its 8,528 faces. Eleven water brushes fill the pools, four rotating brushes turn, two doors open, and 172 non-solid decorative brushes plus 106 sprites carry the plants and light beams. Sky is ark1. The archive also brings two ambience sounds, four sprites and a radar overview.
