Light is, by most accounts, a pretty good thing. It's warm, it makes plants grow and, perhaps most importantly, allows us to see. At least, that was its most important function. Now, thanks to Alan Wake, we know that light's ultimate purpose is to disintegrate monsters. In the small mountain town of Bright Falls, a simple flashbang becomes a weapon of mass destruction and an ordinary road flare is transmogrified from a beacon of hope to a harbinger of doom. If you don't believe us, check out the new teaser -- part of a week-long Alan Wake feature at 1UP -- after the break.
