This mod is done by me. I took the original map file and converted to Source 2 format and added to Half-Life: Alyx. In process, I converted assets of Half-Life 2 to Half-Life: Alyx as well.
Things i was able to do was very limited since Valve didn't share SDK with the public yet. I started this project around 24 March and planned this since around January. You can pretty much say, this is the first Half-Life: Alyx mod.
Note: I have no plans to share this yet since it's just a showcase demo and nothing more.
