GoldSrc. It is a modified version of the SPR format used by 
Quake, adding a dedicated color palette and additional translucency formats.

Image format types
| Format | Explanation |
|---|---|
| Normal | Opaque image with no transparency |
| Additive | Same as Normal; Additive translucency can be achieved for any image format by changing the sprite's rendermode (either in a sprite entity, or via code) |
| IndexAlpha | Single-color with 8-bit translucency |
| AlphaTest | Binary alpha-tested transparency; pixels using the last color in the palette will be transparent |
Orientation types
| Orientation | Explaination |
|---|---|
| Parallel | Rotates to always face the camera |
| Parallel Upright | Like parallel, but doesn't rotate around Z axis |
| Oriented | Rotated in map editor to face a specific direction |
| Parallel Oriented | Combination of parallel and oriented. |
| Facing Upright | Like parallel upright, but rotated based on player origin, rather than camera. |
