Two brothers have opened an office to investigate mysterious events. One day the phone rings, and a voice asks them to clean out a huge haunted house. They pack their gear and head for the spooky mansion, where creatures, traps and mysteries are waiting.
The house has 20 rooms, and each one is a level to clear. Each player controls one of the brothers. Defeat the ghostly creatures, avoid the traps and work together to finish every room. Both characters' remaining lives are shown at the top of the screen. The first stage shows you which keys to press, so you can learn the controls as you go.
