As they progressed, oddities leaked into the apartment. A chime like the game’s menu sound came from the kitchen. A small, translucent smear of pixel light ghosted across the living room TV, following their steps with an uneasy slowness.

He deleted it; the tablet responded by showing a photo of their hallway, taken from just outside the door.
