Nice but, as I had read on the comments the project is currently unactive. The networking is not working and there are developers who wish to help with it but the main developer is not responding at all. Also this engine support only WON version mods... Even of that Counter-Strike 1.5 cannot be started. There is also bugs on the classic Half-Life.
There is much more work to be done. At least the source code is available.
