Grey Source is a modified Half-Life 1 engine made specifically for creating standalone games with an early 2000s feel. The aim of the engine is to make old new again.
The first two digits of of the build number are the year of release. The second two are the month. So, if a build were to be released in January 2001, the build number would be 0101. If a build was released in June 2013, the build number would be 1306.
- Viewroll (restored after Valve's removal of it in 2003)
- Viewmodel bob tilt (restored after Valve's removal of it in 2003)
- Minor bug fixes
- Complete code overhaul, which allows the Visual Studio solution to build under VS 14 2017 and VS 15 2019.
- Improvments to viewmodel bob tilt and viewroll
The master branch contains the unmodified SDK of Grey Source. You can clone this branch to make your own Grey Source game, from the original engine just in case you don't want any propietary versions of Grey Source used for games developed by PHOENIX. The branch will always be up-to-date with the latest release of Grey Source.
