About A.D.D. (Anomaly Detection Department)
A.D.D. (Anomaly Detection Department) is about investigating the Backrooms, abnormal physical spaces that cannot be explained by the laws of reality. You plan expeditions by connecting employees, exploration areas, equipment and nodes into a route. The areas you visit first and the equipment you choose affect the records recovered and each expedition’s outcome; even the same employee can produce different results on different routes.
Process the records
Expedition records have no value on their own. You select materials and refine them into datasets for HALCYON INDUSTRIES, then submit the completed results to obtain resources and new options for your next assignment.
Make your choices
As you work, you encounter unexpected choices. The game does not tell you what is true or whom to trust; your decisions and their consequences are yours. Your task is to produce the results HALCYON INDUSTRIES demands.
