God had created the world with Light and Shadow completing each other, maintaining the balance of events. The Tribe of Light are humans, living on the surface, the Tribe of Shadow has many different creatures, who dwell underground. To sustain peace and harmony between the tribes, a huge stone tablet called Words Worth was erected. But one day, someone has shattered the tablet. Both Tribes blamed each other and began a bloody war that has been raging for hundred years. Finally, the king of the Shadow Tribe sends his son, the brave Astral, to find out what really happened to the tablets, and to restore peace in the world. Words Worth is primarily a first-person dungeon crawler. Even though there are a few "friendly" areas, such as a town where the hero can rest and buy supplies, most of the game is spent in dungeon-like, maze-like areas (with an auto-map feature). There is no party in the game: Astral has to face the enemies alone. The enemies appear randomly, and the combat is turn-based. The game has scenes with nudity and sexual situations.
