Alan Wake on Steam this February -- the developer's first self-published title -- with a hefty FAQ session on its forum. Steam's Alan Wake will not be available on Mac, won't use Games for Windows Live and won't have a demo. It will use Steamworks, support keyboard and Xbox 360 controller input, and will include The Signal and The Writer DLC packs with the game.
Alan Wake on Steam can support stereoscopic 3D through NVISION 3D, although it is performance-intensive, Remedy warns. For normal (see: "unfancy") gameplay, the expected system requirements are fairly standard, as you can see -- no flashlight required -- just after the break.
