File type specification:

Game file type icon Game file type

bsp file icon: bsp filetype icon

Half-Life, Team Fortress, Counter Strike - 3D first person action game map file.

The format is similar but not identical to the BSP file formats of the Half-Life 1 engine, which is based on the Quake 1 and Quake 2 file formats, plus that of the later Quake 3.

The *.bsp file contains the vast majority of the information needed by the Source engine to render and play a map. This includes the geometry of all the polygons in the level; references to the names and orientation of the textures to be drawn on those polygons; the data used to simulate the physical behaviour of the player and other items during the game; the location and properties of all brush-based, model (prop) based, and non-visible (logical) entities in the map; and the BSP tree and visibility table used to locate the player location in the map geometry and to render the visible map as efficiently as possible. Optionally, the map file can also contain any custom textures and models used on the level, embedded inside the map's Pakfile lump.
