Left 4 Dead's Soundtrack is composed by Mike Morasky. He was also involved in the soundtrack for Team Fortress 2, another highly successful franchise from Valve. Music is a big part of the Left 4 Dead experience. It brings suspense to a bad situation, alerts you when something happens, and sends chills down your spine. The music is dynamic and is controlled by Left 4 Dead's Director. Most of the music is centered around the experience of the game through the Survivors, though music does play while playing as the Infected. __TOC__
