Microsoft has said that Alan Wake will be supported by additional downloadable episodes on Xbox Live following release.
"Story-driven like a TV series, Alan Wake will be told in episodes, with even more episodes available on Xbox Live after its launch this year," Bach, who is president of Microsoft's Entertainment and Devices division, said during his CES keynote overnight.
"Imagine the TV show Lost as written by Stephen King and filmed by David Lynch and you have Alan Wake."
Well, technically nobody has Alan Wake, because it's been delayed about 48 times, but we are assured it will be out this year on Xbox 360. A planned PC version has been shelved for now.
