A fast-paced online action game in which players take on the roles of ghosts or ghost hunters. The ghosts hide in inconspicuous furniture and rush at the attacking hunters, who must find and destroy all the ghosts before the clock strikes midnight. After all, at this time the light goes out, and all the dead ghosts return as vengeful spirits. The balance of power is changing and hunters become victims. They must try to survive the onslaught of ghosts until they can escape.
