The highly anticipated downloadable content pack for Left 4 Dead 2 will arrive pretty soon (by the end of March) and we have a bunch of new screenshots for you to look at, as well as some fresh new details from Valve regarding The Passing – because that’s the name of the DLC!

The Passing DLC will be truly memorable for the fans of the series since the new cast of Left 4 Dead 2 will meet the original cast from L4D. However, it won’t be everything as expected: we won’t be able to play any of the original characters! Bill, Zoey, Francis, and Louis will be AI-controlled characters that will only help the new cast get through The Passing.

Even this could be considered as a half-disappointment, there’s some good news: Valve plans to introduce a new infected to the swarm, The Fallen Survivor. These new uncommon infected will give you items when brought down. And… that’s about it! Maybe some extra details will be released in the future. But until then, enjoy the new batch of screenshots from the upcoming Left 4 Dead 2 DLC, The Passing (click each image to enlarge)!
