Survive the night at the Hopkins' Cliffside, a tense first-person anomaly-detection horror game. Investigate anomalies, wield an ancient artifact, and uncover the secrets of the cliffside. Will you survive until dawn, or will the anomalies consume you?

In Nightwatch at the Hopkins' Cliffside, you are sent as a member of the Committee for Handling Illogical Phenomena (CHIP), tasked with observing and investigating reality-defying anomalies at the remote cliff. Armed only with a strange Tetrahedron artifact and a flashlight, your task is to endure one night while identifying disturbances. However, as the clock ticks, the anomalies become more frequent and dangerous, and most importantly, some of them will hunt you down. Will you survive until dawn?
The Anomalies

Anomalies are distortion of reality that take many forms. Some are subtle, like inverted rainfall or disappearing stars, while others are more intrusive - gravestones appearing in the garden, ships materializing at sea or vast pyramids sunk in the water. Each anomaly is divided in four categories (Natural, Monstrosities, Luminous and Reality) and detected by using the Tetrahedron. Anomalies are random, with some spawning in variations. The Entities

Not every anomaly is harmless. Certain manifestations develop into hostile entities that actively hunt or disrupt you. The Strider prowls through windows across the house, The Wanderer digs out of the ground, and the Observer pulls your focus toward its fixated gaze. Each has its own patterns of behavior, forcing you to adapt how you move through the estate in order to survive.
The Story

The Hopkins estate holds more than just anomalies. Scattered notes, letters, and reports document the history of Everett Hopkins and his involvement with C.H.I.P., as well as its story. Explore the rich, handcrafted environment to piece together found knowledge to reveal a much larger story.
In recent years, anomalies have begun appearing worldwide, growing in frequency and intensity until they could no longer be ignored. As governments could no longer deny their existence, investigations commenced. It quickly became clear that the anomalies posed at least some kind of a global threat. Scientists from around the world are now working together to create the first tools capable of stopping these aberrations
Prepare yourself for a night of suspense, mystery, and psychological horror. The Hopkins' Cliffside is waiting, and it’s anything but ordinary.
