In the article was short description about "day scene":
At a hotel in New York earlier this week, three of Remedy's top men showed me about 20 minutes of Alan Wake. We first looked at part of the game's first chapter or, as the studio has been calling it in the model of favorite shows of theirs like Lost, "episode." Alan and Alice were driving into Bright Falls, heading over to a diner where they would meet the man with the keys to the house they'd be staying at. The diner was filled with ambiance and optional diversions. The waitress recognized Alan and squealed to him about how she was his biggest fan and even had the cardboard cut-out commemorating one of his novels to prove it. Sure enough, at the doorway was a cardboard Alan Wake.
As one of Remedy's developers walked Alan to the back of the diner, our hero encountered two old-timers sitting in a booth, jawing about something or other. One of them asked Alan to play a song on the jukebox. Further to the back, Alan encountered a lady in black, her face covered in a veil. She wasn't the person who was supposed to give Alan the house keys, but she had them. And, she creepily added, she'd come by later to meet his wife. She demanded it.
And according article also action scene are more deep than what videos show:
Under a night sky, the trio worked their way to the top of a dam. Hounded by possessed people and flocks of birds, they did their best to survive. On the road atop the dam, the Remedy guys had Alan commandeer a big spotlight. He could use it as a turret, but any light source Alan uses has limits. His flashlight can run low on batteries, forcing the player to use one of his reserves. The spotlight can burn itself out. So after a little bit of spotlight blasting, Alan left the thing idle and was left to his flashlight and handgun. Lake told me that spotlights and other light sources can be used to corral an enemy. Leave a shaft of light beaming on the right and enemies will avoid that region.
As enemies swarmed Alan, the best defense turned out to be a flare gun. Firing this at several onrushing enemies triggered a stylish slowdown effect. The enemies recoiled and Alan dodged. But the mysterious dark force had plenty of other things in store for Alan. Unfortunately, as it got hectic, the demo ended.
