It's hard to say, I can't continue Black Mesa: Classic. Problem is that I have no experience in modding, lack of knowledge in programming and stuffs and no free time to to this project. I gave up because it's literally impossible to do this project without a big team of handful people, although if I have one, I can't just direct them to do something immediately just like a big company making games.
What's happening now?
Discord Server and this ModDB page is probably going to be shut down and deleted. It will be another decade until someone would dare to continue Black Mesa: Classic and finish it until Xen.
