Hool10: How close are you working with Microsoft in delivering DLC with the XBOX 360 version?
MB: I'm assuming by "DLC" you mean 'downloadable content" for the 360 version of Left 4 Dead. We're still working out the specifics of that.
Hool10: Could you tell us what the other two levels are or describe them as well as the progress?
MB: All four of the campaigns are playable at this point. We're working on all of the finishing touches at this point ? lots of art content, effects, and so on. We want you to feel like you are in a horror movie while playing Left 4 Dead.
Hool10: Are we having new media such as tutorial videos in the near future?
MB: There will be new media in the coming months, yes.
