I have seen many Blue Shift Source mods (none of them ever got finished) but yours is by far the best one I have ever seen. Also, it fits together with Black Mesa nicely, so even just that puts it above everything else.
I read that you weren’t going to be able to finish this before Black Mesa is released, that’s a shame, but I know it is for the better. Also, since I know you are already a part of the Black Mesa team, I think this should become a DLC of sorts instead of being just a mod. It is just that good.
