Black Mesa: Source was built and founded on the principle that Half-Life: Source did not do the original title enough credit, regardless of the true intentions laid out with the release of Half-Life: Source by Valve Software. Subsequently in November 2004, Black Mesa: Source was founded and set out to reconstruct the original title, giving it the new environments, models, and abilities it deserved on the Source engine. This total conversion will not require Half-Life: Source installed on your system to play, only a legitimate and working version of Half-Life 2. At the present time, Valve Software is not associated or involved with the development of this project.
