Along with detailing some of the backstory of each original character, the comic series gives players a look at the tale woven in the upcoming downloadable content "The Sacrifice." In total, the comic will stand at 150-plus pages and also explore the death of one member in the zombie-killing squad.
For gamers looking to preserve the memory of the fallen, Valve has released parts one and two of the comic in .PDF format. There will also be two additional versions of the series released at a later date: one version with no text and another sans text, speech bubbles or sound effects. "This should help get the comic localized and give people the raw panels to play with and make their own comic," the L4D team wrote on the game's official blog.
