The Passing is the first downloadable add-on for Left 4 Dead 2. Xbox 360 players have to shell out $7 for the new content, so we've posted a proper review to help them decide whether to buy it or to pass (yeah yeah…couldn't resist). For PC players, this content is not only free, but it will also be automatically installed the next time you fire up Left 4 Dead 2 (if it isn't there already!).

What is the new campaign like? What are Mutations? And how do the L4D2 survivors get along with the old guard, the original L4D crew? To satisfy your curiosity, here's the multiplatform video breakdown of The Passing. Enjoy!
