Modification

Mod or modification is a term generally applied to games, especially first person shooters that run on the open source Quake engine (Including Doom and Half-Life). Mod's are made by the general public, and are entire new games upon themselves. They can include new items, weapons, characters, enemies, models, modes, textures, levels, and story lines. They also usually take place in unique locations. Mods can be single-player or multiplayer

Among popular mods, none is more well known then the Half-Life multiplayer mod, Counter-Strike, which was released shortly after the original game, and host upwards of 1 million games per day on dedicated servers.

Mods in general are required to be open source (Free) if they include any parts from another mod, or the main game.
