Playthrough of No Mercy with dev commentary, talking and showcasing the development of the original Left 4 Dead by the mouths of Turtle Rock and Valve.
Disclamer: The game looks darker than usual because I forgot to disable the Horror color correction mod I had installed. Even then I think it actually enhances L4D's already heavy atmosphere.
