The Sacrifice

The Sacrifice is an upcoming three-map DLC for both Left 4 Dead and Left 4 Dead 2. According to an interview with PC Gamer, it is set be released on October 5th. It will be free on the PC and Mac (to be launched with the Mac version of Left 4 Dead 2 at the same time ), and cost 560 Microsoft points for the Xbox 360.

It will be the sixth and so far chronologically last campaign for Left 4 Dead. Whether or not there will be other, later DLC is unknown, although it was hinted that there will be more; in a Valve interview it was said that the Left 4 Dead story was "Far from over!" and players can choose which one of the original cast 'meets their maker' in the upcoming downloadable content.
