When the player enters the house through a window, it yields a number of interesting objects: an ancient brass lantern, an empty trophy case, an intricately engraved sword, etc. Beneath a rug a trap door leads down into a dark cellar. But what appears the cellar is actually one of several entrances to an underground area—the Great Underground Empire. The player soon encounters dangerous creatures, including deadly grues, an axe-wielding troll, a giant cyclops and a nimble-fingered thief.
