Alan Wake: The Signal

Continuing on where the main game finished, Alan finds himself outside the diner in a nighttime Bright Falls, which quickly changes to daytime. Entering the diner, a surreal déjà-vu dream of the events plays out similar to when Alan first arrived, with everything eerily familiar but out of place. Alan cannot remember where he was before this moment but knows he must go to the back of the diner, which he forcibly enters. Zane talks to Alan and warns him that he should go no further and that Alan must focus. Zane plays a video of Alan struggling with reality and even tells of events playing out when Alan realises where he is: The Dark Place.
