The last piece of downloadable Alan Wake content, The Writer, will be released on 12th October for 560 Microsoft Points (£4.80 / €6.72).
Those details spilled from a video unveiled on GameTrailers that showed Alan Wake exploring a dream-world, where cars float and strange things happen (are you going round the twist?).
"Every journey has a destination," the video spouted. "Every question needs an answer. And words have power.
"End the nightmare."
Alan Wake was released exclusively for Xbox 360 in May. One other piece of DLC - The Signal - has been released since then.
