It gives me more of Alan Wake vibes than SH TBH, although I'd like to see both. Also it might be just a tech demo, similar to RE engine's kitchen demo.
Nothing about it gives Silent Hill vibes. Not the audio, not the art style. I really hope it's not that. Doubt any of you would think so if the tweet didn't make that claim...
Lol @ people commenting on the visual quality from this, they could show Alan Wake in such a blurry fashion and you'd be impressed if it had reflections I guess
