"DIASTONE: Memories" is a first-person photorealistic horror game.
Our story begins in 1910 in Transylvania, where Adam Taylor, a nineteen-year-old boy, lives with his parents in a house on the edge of civilization. One day, upon returning home, Adam hears that his parents have started quarreling in the attic. Suddenly, all the lights in the house turn off. Picking up an old oil lamp, Adam goes in search of his parents. However, when he reaches the attic, there is nobody there. An unknown man has appeared in his house, and all the rooms have changed. Time has ceased to have a specific meaning.
In one of the rooms, Adam finds a note from an unknown person who claims to be Adam Taylor. Who is he? What does he have to do with what's happening to Adam?
This story continues in the twenty-first century, when Edward, an orphan, starts living in the very house where Adam's family once settled. He encounters the same creature. Will history repeat itself? How will Edward cope with this power? What happened to Adam?
