Encyclopedic overview
Source (also referred to as Source 1) 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. Valve used Source in many of their games in the following years, including Team Fortress 2, Counter-Strike: Global Offensive, Dota 2, and the Portal and Left 4 Dead franchises. Other notable third-party games using Source include most games in the Titanfall franchise, Vampire: The Masquerade – Bloodlines, Dear Esther, The Stanley Parable and Garry’s Mod. Valve continues to support several Source games into the present day, and would incrementally release new branches of the engine until it was succeeded by Source 2 in 2015.
