Gemstone Warrior is an action game with adventure elements. 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. The hero has to go underground because of demons. They stole the gemstone from humans, because they were jealous of the good magic it brought to humankind. They broke it up and spread it throughout their dungeon, to hide it. This game is not just a "shoot-em-up"; it has many of the features of that style of game, but also gives players time to think. It includes a pause which helps one map and also to freeze a room, to see what is running toward the Gemstone Warrior.
