In its pacing and structure, Alan Wake is similar to a thriller television series, with episodes that contain plot twists and cliffhangers. The game consists of six episodes, and the storyline continues in two special episodes, The Signal and The Writer, that were made available as downloadable content (DLC) in the year of the game's release. Additionally, a six-episode live-action web series called Bright Falls acts as a prequel to the game, and a number of related books also expand upon the Alan Wake story.
