Source is a 3D game engine developed by Valve. It debuted as the successor to GoldSrc in 2004 with the releases of Half-Life: Source, Counter-Strike: Source, and Half-Life 2. It is most well-known for its usage by Valve, but the engine has been used both by small teams and individuals to create modifications of Valve games,^[1] and other studios creating distinct games, notably Troika Games' title Vampire: The Masquerade – Bloodlines. Valve continued to create incremental updates to the Source engine after its 2004 release, most of which coincided with games created by Valve. In the late 2010s, Valve created the Source 2 engine to replace Source, with it publicly debuting alongside Half-Life: Alyx. The Source engine is most well-known for its advancements in physics, AI, and graphics.^[2]
