About This Game
Welcome to A.D.D.
HALCYON INDUSTRIES has confirmed that unexplained anomalies have recently been occurring around the world.
Our investigations indicate that these phenomena are connected to “abnormal physical spaces” that cannot be explained by the laws of reality. For convenience, we refer to these spaces as the “Backrooms.”
The information currently available about the Backrooms remains limited. Your assistance is required for further investigation.
Rest assured. HALCYON INDUSTRIES always places the safety of its workers first.
Connect employees, exploration areas, equipment, and nodes to construct an exploration route.
The records recovered and the outcome of each expedition will vary depending on which areas are visited first and which equipment is used.
Even the same employee can produce entirely different results depending on how you design the route.
Records recovered from expeditions have no value on their own.
Select the necessary materials and refine the records into the datasets required by the company.
Submit the completed results to secure the resources and new options needed for your next assignment.
As you continue your work, you will encounter unexpected choices.
You will not be told what is true or whom to trust. The choices—and their consequences—are yours.
Your job is to produce the results HALCYON INDUSTRIES demands.
