Mods



A mod (short for "modification") is software created by a third party group (such as a mod team) or company that modifies one or more aspects of an existing game. These aspects may include, scripting, code and new maps. Aesthetic aspects such as replacement models, textures and sounds usually aren't considered to be 'mods' when released on their own. A total conversion is a mod that runs on the engine of the game it is based on and shares much of its code, but otherwise replaces almost everything else and uses few or none of the original game's assets (such as textures or models).

Many Half-Life and Half-Life 2 mods are listed at the site Mod DB. Many of these Mods can be downloaded for free.

A large number of mods based on the Source engine are in the works and quite a few have been completed or are in beta stages.

Some original mods, like Counter-Strike, Team Fortress Classic, Day of Defeat and The Ship have been 'adopted' by Valve and made into commercial games.
