Here’s a glimpse of what will come out when the deathmatch version of Black Mesa will come out.
It is not an official map.
You know, the last time a thread like this popped up, it was clearly copied from Black Mesa and the guy threw a fit when it was pointed out.
Yours has shades of some bits being taken from BM, but I appreciate that you took some of your own direction. There’s really not much to say going off this screenshot of a wall.
Oh God don’t remind me. You mean when his stuff was obviously and hastily copied from BM screenshots, but incredibly sloppy and shoddy looking in comparison, and yet he used the rushed pace he managed to shit out his rip-off efforts as justification to passive-aggressively slag off the BM Devs as being slow and rubbish? All while apparently harbouring the hope that they would hire him to help finish the mod? Too late, you’ve reminded me. 
To the OP: Got any more shots you want to share? You’re already off to a better start than the weirdo we’re talking about. 
One last screenshot was added to the original post.
There’s a map called dm_office… so you could call it dm_office2 or another name
