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.
What I wrote after I finished the first public release:
"Ok I have finished the game now and it was amazing! Thank you!
I will give you my feedback:
The beginning was a bit shaky. You didn't get the crowbar a the same time as in original Half-Life so I spent a lot of time running around looking for it. But then I got it somewhat later. So that was a bit confusing.
I only encounter two bugs. Firstly I lost most of my weapons during "Forget about Freeman!". That meant I lost the Gauss Cannon and I never got it again (so I never had any time to try it out). Maybe you should add more of those, for example you could add one just before you enter the teleportation room during "Lambda Core". Because there is one there in the original Half-Life.
The only other bug I encoutered was when I was going to flood the reactor coolant tanks. I flooded tank nr 1 then i flooded tank nr 2. But when I had finished flooding tank nr 2 tank nr 1 all of a sudden wasn't flooded anymore so I had to do it all over. And all the monsters that I had killed and all the creates that I had broken were back.
Other than that the game was fantastic and I'm really looking forward to your interpretation of Xen!"
