It took 90 minutes for my friends and I to finish the playable teaser for the upcoming Silent Hills. There's no combat, no mechanics outside of walking around and looking at things, and the entire experience takes place in one environment.

Have you guys heard of the new Silent Hills demo recently released on PS4?
