A military airstrip at dusk under a torn stormy sky: a cargo plane on the tarmac, hangars and service buildings, palms and brush along the fences, birdsong in the background. Two bomb sites sit around the airfield, and the CT side is unusually crowded — 22 spawns against 16.

One of Barney's official maps of the early retail era; the map itself later left the rotation, but its texture set, de_airstrip.wad, still ships with every 1.6 install, which is why the archive does not need to carry it. This is his heaviest CS geometry: 12237 faces with all 78 textures compiled into the .bsp, against de_dust2's 5383 faces, in a 4288 × 6752 × 1672 unit volume. The archive installs the .bsp, the tornsky skybox, five bird ambience tracks, the plane and vegetation models, the sprites, the radar overview and a .res file.
