Remedy Entertainment wants the ending of Alan Wake to remain a secret. They even go as far as saying that it won't be included in preview copies of the game, afraid that press or others would reveal the end before gamers have a chance to experience it themselves.
"I think we're going to be insanely careful about how much of the story we reveal. We'll clearly discuss with some of our friends at Microsoft whether we even give the ending of the game for anybody's preview. I'd like to hold it back, I don't want anybody to spoil it for the audience," managing director Mattias Myllyrinne tells G4TV.
Given the nature of Alan Wake, the town of Bright Falls and the narrative, it is highly probable that knowing the reasons for the strange phenomena that takes place would spoil the experience.
