There will be downloadable content add-ons for Left 4 Dead 2, that's a given. But that doesn't mean the campaigns will be called "Miracle" and "Apocalypse," two names discovered by gamers who loaded up the game's code base and started poking around. Speaking at a Eurogamer Expo event, however, Left 4 Dead 2 writer Chet Faliszek said people are jumping to conclusions.
"The DLC mentions in the demo code were erroneous," reads a Eurogamer report from the question and answer session of Faliszek's talk, "and down to the fact that to do test submissions for Microsoft you have to simulate DLC, among other things."
Valve was forced to include names for downloadable content as part of the submission process to get the Left 4 Dead 2 online. It's possible "Miracle" and "Apocalypse" will end up being the final names for future downloadable content, but they could also be code names -- or just red herrings.
Sounds reasonable to me. "Apocalypse" sounds damn cool, though.
