Run. Think. Shoot. Live. Source. Black Mesa is the Half-Life 2 total conversion of the original Half-Life game. Utilizing the Source engine and its endless array of possibilities and powers, Black Mesa will throw you into the world that started the Half-Life continuum and introduced Gordon Freeman to the world as a gun-toting, bullet-dodging Ph.D. in Theoretical Physics.

This game is good but it would be cool if you add more weapon than the ogirinal
Great graphic anyway

So is Black Mesa a complete copy of Half life?
Because I want to play Half Life but the graphics are not the best. And I don't want to play this if its not story-loyal to Half Life 1.

Played it from start to end, got annoyed at some jumping parts, but that's just me hating jumping parts.
10/10 from me.

Just a question, the part with those three pumps, just after your first encounter with the oversized fish aliens, are we supposed to be able get to the other end without jumping trough the crushers, but by stacking barrels near the small container and jumping on them?

I discovered an interesting bug in Black Mesa during my walkthrough.

Before the Tentacles kills that guard shooting at them, I did a quick save. Then when I quick load, the Tentacles attacks the guard, but the guard doesn't die.

It gave me an easier chance of sneaking around the Tentacles.

How's that for a bug?
