HELLO! and uh… I found it by looking up Half-Life videos.
Yup 
I think it was mentioned on some gaming websites and I followed the link 
youtube.
I can’t remember either it was so long ago. I probably stumbled across it after trying to find out what features were improved in Half-Life: Source, becoming gravely disappointed, and wanting more. I guess wanting is good sometimes.
Edit: Lol, didn’t originally have the space in Half-Life: Source, so it turned out as Half-Life:Source. Thats actually how I felt about it, too 
I browsed through all the mods of Half-Life 2 on moddb in alphabetical order. I squeeled in delighted finding this one.
I honestly can’t remember for the life of me where I first heard about Black Mesa. Perhaps ModDb…
I don’T remember where I found out about it… Are there ads on some sites? I’m not sure if I found BM from Concerned, or the other way around.
Otherwise, probably a post on some random unrelated forum.
Hmm, i was told by some combine about BMS, they were sittin’ near mah house…
Mmmkay those were not combines, just guys with combine suits and those were my friends >.>
My bro showed it to me, and I was like
However, I knew nothing of HL1 at the time, I just thought “Hmmm, that’s a good looking mod!”
Were they from SCIENCE and OUTER SPACE?
I think I first heard of BMS somewhere on the internet some time ago, possibly not too long after development started on the mod. At first, I wasn’t very interested because I hadn’t play HL1 yet at that time, but after I finally played HL1 about two years ago and realized how amazing it was, I started following BMS quite closely.
I searched up High Def packs for Half Life Source and found this.
add me to the list of people that found BM from wikipedia
I can’t remember at all how I met BM. But I’m just happy I did.
It was behind the couch the whole time!
Lookin’ for Sourcemods.
I was minding my own business, reheating a lovely casserole in the microwave when some guy came in and blew it up. Then he left and, as just when I finally finished cleaning the microwave, I heard screaming and a large alien went by, shooting bolts of electricity from his hands! So, I ran to my office and began researching on the computer and found BMS. I hope that alien caught the guy that blew up my breakfast.
Oh, wait. No, I found BMS via a friend of mine. He knew I was a HL fanatic (I’ve played through and/or beat HL, HL2, HL2:E1, HL2:E2, Opposing Force, Blue Shift, Portal, AzureSheep, Point of View, and Portal: Prelude–the last two I haven’t beaten yet), so he told me about BMS…I think it must’ve been about two years ago.
Just last year, before the Server crash, I was looking around on Google for GMod addons (This was before I found Garrysmod.org, mind you) And this came in about seventh place.
Glad I found it
