Remaster of 半衰期. It is critically panned by most gamers since 2013 due to the huge amount of bugs that was introduced when the game was updated to  起源2013. Prior to the 2013 update, it was generally positively received by critics and most gamers, but some are disappointed over the game graphics (especially the textures) that are largely unchanged, while also having a realistic 3D Skybox and water effects. A unofficial fan remake of 半衰期, called  黑山 was later started development in response of those criticism, which was first released in 2012 without any Xen chapters and was much shorter, and later in 2020, a full release with contains the Xen chapters. |

起源（Source）是 Valve 基于金源开发的一款3D游戏引擎,因其在图形、物理和AI方面的进步而闻名，这使得游戏在当时非常逼真，同时还可在性能较差的旧硬件上扩展。起源被 Valve、第三方公司与社区模组开发者们所使用，被用于开发了超过百款游戏。现在，第一方使用的起源2已基本代替了起源，但模组作者与一些第三方公司仍在使用起源，且其仍获得定期维护与安全更新。
