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.

Somehow, Black Mesa exceeds expectations. It not only is accurate to even the little details, but the attention to detail exceeds the Half Life games. Keep in mind that it has a few stability problems and is not complete.
