Early prototype builds of Left 4 Dead 2 include countless leftovers from the first game. This includes models, textures, and audio used for the game. However, the prototypes' audio files contain over 3,000 unused and previously lost voice lines from the original Left 4 Dead. With so many to choose from, these voice lines range from uninspiring line outtakes to more interesting tidbits like cut level ideas and extreme vulgarity.
