In the Xbox 360 debug version of Alan Wake, hidden in the Downloadable Content menu, currently sits a good amount of details on the first two pieces of DLC for Remedy's latest title.
Already announced, the first piece of DLC is called, "The Signal" and if the countdown timer on the content is anything to go by, it should be dropping around June 1st (the countdown currently sits at 27 days).
The description for the first episode states that it "answers many of the questions the end of the game raised," including "what happened to the writer after the dramatic events of Season One?"
Yes, this is the same DLC that all new purchasers of the game will receive with their game.
The second DLC, which is slated as "coming soon," is called "The Writer," with the description noting that we see "Wake struggling to not lose himself in the torrent of nightmares that assault him."
A few weeks back, when we were under the dreaded embargo and were sworn to secrecy under the penalty of castration, there was also a listing for a "Developer Commentary." However, that content listing has since been pulled and its existence is currently unknown.
As far as price goes, Microsoft told us earlier that the price hasn't been confirmed yet and is likely to change. Expect some sort of official announcement soon, but in the meantime, just know that Alan Wake's experience will continue long after the game has been completed.
More Alan Wake is most definitely welcomed though, considering how utterly fantastic we found the main game. If you missed our review, check it out now, it's spoiler free!
