The Gemstone Warrior is part action game, part adventure game. Players work their way through an underground catacomb, doing three things at once. First they need to find five pieces of a gemstone, spread throughout the maze. Second they need to avoid getting killed by the guardians of the catacomb. Finally they need to map the game, because the place is so large that it is easy to get lost. Once the Gemstone Warrior has collected the five gemstone pieces, he needs to move back to the point where he began the game.
