Alan Wake, Remedies first game since Max Payne 2, was originally scrapped for PC for dubious reasons. Apparrently Remedies desire for a PC version never died out, and in late 2011 they announced its coming. With this opportunity, Remedy Entertainment also released a new trailer of the game, dedicated to the PC version which you can view on its steam page.
Alan Wake for PC includes the “The Signal” and “The Writer” DLC packages and all the necessary features a PC game needs, be controlled with a mouse and keyboard or gamepad with both methods working well, the interface has been adjusted allowing weapon switching with the number keys and mouse wheel, its playable on all 3 screen ratios, optimised for quad core cpu's, with adjustable FOV and a 'hide hud' option for those who prefer realism.
Remedy still show further improvements through patches, like allowing the game to played on resolutions smaller than 1024x768, for it to work well on 3 core machines and bindable mouse 4 and 5 buttons.
