GoldSrc, sometimes called the Half-Lifeengine, is a proprietary game engine developed by Valve. At its core, GoldSrc is a heavily modified version of id Software's Quake engine. It made its debut in 1998 with Half-Life and powered future games developed by or with oversight from Valve, including Half-Life's expansions, Day of Defeat and games in the Counter-Strike series.
Based on id Software's open stance towards game modifications, their Quake series became a popular subject for player mods beginning with Quake in 1996. Spurred by user-created hacked content on their previous games and the company's desire to encourage the hacker ethic, Id included dedicated modification tools into Quake, including the QuakeC programming language and a level editor. As a game that popularized online first-person shooter multiplayer, early games were team- and strategy-based and led to prominent mods like Team Fortress, whose developers were later hired by Valve to create a dedicated version for the company. Id's openness and modding tools led to a "Quake movie" community, which altered gameplay data to add camera angles in post-production, a practice that became known as machinima.
