The Sacrifice

The Sacrifice is an upcoming three-map DLC for both Left 4 Dead and Left 4 Dead 2. According to an interview it might be released on October 5th.[citation needed] 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 last campaign for Left 4 Dead. Whether or not there will be another 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!"
