It's a world where everyone is gone.. A lovely English Village, you wander around finding clues and listening to "echos" of those who were, to discover for yourself
Exactly what it was that happened. No traditional gameplay, no puzzles or fighting. Just piecing together for yourself, the story, from clues you can find and the "echos" .
Also ps4 only as far as I know.. I enjoyed it..I finished it in about 5 hours (one sitting).. Kokaku (sp) has a review out..
It autosaves.. You must watch for the small icon on the lower right corner when you are getting tired..You can not save it yourself.
-edit-
There is another trailer on youtube that shows more.
