The Source Engine is Valve Corporation's current game engine, which debuted in Counter-Strike: Source. Since then, it has had many improvements with the release of subsequent games, such as the addition of advanced facial animation in Half-Life 2: Episode One, and better support for cinematic-style animations, shadows, lighting and long rendering distances in Half-Life 2: Episode Two. One notable addition was that of HDR and bloom support with the technology demo Half-Life 2: Lost Coast. Support for soft-particle physics was added with the release of Team Fortress 2.

Origins

The Source engine was built on top of GoldSrc, Valve's previous-generation rendering engine, which was itself based on the original Quake Engine, with some changes from the Id Tech 2 engine incorporated. Source also includes a heavily-modified Havok physics engine, and was mainly developed after the original Half-Life was released, and once ready, Valve's internal projects were slowly transitioned to the new engine.

Cheats

To begin with, open the developer console by pressing tilde ("~"), although this will only work if you've previously enabled the developer console in the game's advanced keyboard preferences. Before any cheats can be used, the command sv_cheats 1 must be entered. This will only work if you're running the server (i.e. you're playing a single player game, or hosting a multiplayer game), so you can't cheat in normal multiplayer!
