Museum 13: Night Guard

You are the night guard of Museum 13. Every few seconds the lights flicker and something in your room changes. Snap it with your camera before the next blink. Miss it, and it starts to stir, then wakes and comes for you. Spot the anomalies room by room until 6 AM, alone or with up to 5 friends, and see how many of the 13 Nights your crew can last. #Horror
