Turtle Rock annonserte nylig at historiedelen til Left 4 Dead som heter Dam It nå er tilgjengelig for nedlasting.
På Turtle Rocks forum skrev MacMan følgende:
"Just finished putting the Dam campaign that we streamed a while back into a L4D addon. It's gray box, and some code features are missing but it's playable from beginning to end. It also includes two standalone survival maps that never shipped."
En rask tur innom historiedelens nettside viser dog at den har en rekke ulike problemer, men vi antar at Turtle Rock jobber med å utbedre så fort det lar seg gjøre.
