'''WAD''' is the file extension for [[Half-Life]] texture packages.  An acronym for ''Where's All the Data?'', WAD files first originated in ID Software's Doom as a general purpose file archive to help facilitate [[Modification|game MODs]].  A format of the same name was later used in ID Software's Quake engine as a texture package, then consequentially adapted by Half-Life 1's [[GoldSrc]] engine. GoldSrc specifically uses version 3 of the format, sometimes referred to as WAD3. WAD files typically contain standard texture sets, custom texture sets for individual levels, sprays, HUD elements and fonts.

WAD3 can store 3 types of data (however, WAD format itself allows up 256 types, but GoldSrc uses only 3):
;miptex (0x44)
:Power-of-16-sized world textures with 4 mipmaps.
;qpic (0x42)
:Simple image with any size.
typedef struct
{
    int width, height;
    char data[height][width]; //Image is stored as 8-bit numbers of colors in palette
    short colors_used; //Number of colors in palette (can't be more than 256)
    char lbmpalette[numcolors][3]; //8-bit RGB palette data
} qpic_t;
;font (0x45)
:Fixed-height font. Contains an image and font data (row, X offset and width of a character) for 256 ASCII characters.
typedef struct
{
    short startoffset; //Offset to the character in data
    short charwidth;
} charinfo;
typedef struct
{
    int width, height; //Width is always 256 pixels
    int rowcount; //Number of fixed-height character rows
    int rowheight; //Height of a row
    charinfo fontinfo[256]; //Info about each character
    char data[height][width]; //Same as in qpic_t
    short colors_used; //Same as in qpic_t
    char lbmpalette[numcolors][3]; //Same as in qpic_t
}
All numbers in WAD files are unsigned and little-endian.
