Black Mesa is a remake of Half Life using the Source Engine. Basically from scratch, by individuals who are not employed by Valve. It's like a huge volunteer Ultimate Mod for Half Life.
Technically, so was Half Life Source, but Valve didn't bother to re-do ALL the textures and models and environments. Given the amount of time it's taking for Black Mesa to be finished, can't say I blame them.
