Valve, at today’s X10 event in San Francisco, unveiled “The Passing” as the first batch of downloadable content for the mighty Left 4 Dead 2 and talked about how it’ll relate to the original zombie apocalypse game.
The DLC releases in March and in it, players will meet up with Left 4 Dead 1 characters Francis, Bill, Zoey and Louis, where they’ll appear as non-playable characters.
Valve’s Chet Faliszek told mega-game blog Kotaku that “Left 4 Dead 2’s survivors will rendezvous with the original quartet later on in the campaign, and that they will aid Coach, Nick, Ellis and Rochelle in finishing the third map in the campaign.”
That’s all well and good, but here’s where it gets interesting.
About a month after “The Passing” releases, Valve will release a new campaign for Left 4 Dead 1, which will tell the tale of how Francis, Bill, Zoey and Louis came to meet up with the L4D2 squad in “The Passing.” This unnamed campaign will only be playable in the original Left 4 Dead, not the sequel.
Look for “The Passing” for PC and Xbox 360 in March and more information about the Left 4 Dead 1 DLC in the coming weeks.
