"Black Mesa: Source is a Half-Life 2 modification determined to recreate Half-Life 1 on the Source Engine from the ground up, keeping the original as much intact as it possibly can meaning plotlines, concepts, ideas, level layouts, characters, weapons and monsters will be left the same, except with MASSIVE graphical improvements. We intend to increase polycounts on monsters, weapons, NPCs, weapons and more and put forth the Black Mesa Research Facility the way it was meant to be seen and to give players the chance to fight the battle the way it was meant to be fought. Chapters and the Facility itself will be rebuilt from the ground up with care taken to keep most of the areas the same, but with major improvements in design, architexture, and more."
