Dark Horse compiles Valve comics

Dark Horse Comics has revealed Valve Presents: The Sacrifice and Other Steam-Powered Stories. According to the listing on Comic Book Resources, the 304-page book contains Left 4 Dead's The Sacrifice comic, along with stories from the worlds of Team Fortress 2 and Portal.

The comic book compilation will launch on November 16 for $29.99. Although there are no further details regarding the Portal and TF2 comics, we'd guess they are Valve's online comics in physical form.
