Well, as we’ve informed you back in January, the team behind Black Mesa would be releasing first its soundtrack and then the full game would follow. The gap between the soundtrack and the mod was said to be around two weeks. And it seems that the Black Mesa team is getting ready for a Summer release, as the soundtrack is expected to be released in the following days."
Considering they said the trailer they released a while back was way out of date despite still being freaking awesome is hopefully a good tell that this mod (game?) is gonna be incredible.
Well, it is certain that they are making a mod of a Valve game.
