About Under Investigation
A horror game about investigating anomalies. A police officer finds himself in an abandoned police station where something is wrong. As you explore, you'll encounter anomalies that must be investigated carefully to determine what you're dealing with. Not Everything Is an Anomaly Anomalies aren't simple changes to the environment. They are unnatural phenomena that have no place in the real world. But not everything strange is an anomaly. Some phenomena disappear, change, or fall apart when you investigate them. Your camera is your most important tool. Use it to verify what you see, investigate suspicious phenomena, and determine whether they are truly an anomaly. Don't take too much time The station is slowly going dark. Every use of the camera drains its energy faster, bringing you closer to darkness and danger. Submit your report The longer you stay, the more dangerous it becomes. Find the anomalies, investigate them carefully, and submit your report before it's too late. Can you make it through the night?Read more
