The first of a four-part series of Left 4 Dead comics, entitled 'The Sacrifice', will be released today to mark the countdown to the release of the DLC pack of the same name.
'The Sacrifice' DLC pack is a new campaign for both Left 4 Dead 1 and 2, and will allow players to relive the moment when a member of the original L4D survivors was lost to the brain-munching Horde. That's out on October 5.
The four-part downloadable comic will total 150 pages which detail the events of the new campaign and before it.
Keep an eye on Valve's official L4D blog for more info and a sneaky peek at the comic covers.
