Mods

The Half-Life series spawned countless mods, among which many that became highly popular in the Half-Life gaming community. Some original mods, such as Counter-Strike, Team Fortress, Day of Defeat, Ricochet, The Ship and Alien Swarm (originally a mod for Unreal Tournament 2004) have been "adopted" by Valve and made into commercial games. However some mods such as Garry's Mod having been turned into commercial games remain independent. Some mods are also based on cut content, featured in the released files for Half-Life, and in the leaked files for Half-Life 2.

Some of these mods include minor or major alterations to the original game, others consist in a total conversion, i.e. made from scratch, only using the existing engine, models, sounds, textures, etc. The non-commercial mods can be downloaded for free, as they are not licensing the engine.
