A concrete installation dug into a rocky green hillside. The centre of the outdoor part is a square pit of bare earth fenced off with red handrails, with two earth ramps running down into it and a hatch set in one wall; the surrounding ground is grey slab paving and the site is closed off by block walls with an overhead pipe running along them. On another shot a low bunker facade stands behind a wooden palisade, two timber watchtowers on top of it reached by yellow ladders, hazard stripes painted along the base and a steel shutter in the middle. A further shot goes inside, into a corridor of light concrete panels with a red band along the wall, a railed drop on one side and a long bank of consoles with green readouts on the other.

The map measures 2496 × 4800 × 1568 units, a long and tall layout rather than a wide one. There are 20 spawns per side, so 40 players fit. It carries a single bomb site, no hostages and no rescue zones, and buy zones are auto, so the engine places them at the spawns. Geometry is 5,173 faces on 110 textures, close to de_dust2 in polygon count (5,383) but with more than twice its texture list, and all 110 are embedded in the .bsp. Four doors, four ladders, two water surfaces, two illusionary panels and one breakable object make up the moving parts. The sky is the doom1 set, and the archive holds the .bsp alone.
