Gemstone Warrior

There are three difficulty levels, determining various factors such as the rate at which magic items change their effects and the rate at which more dangerous monsters start appearing.

The game is viewed in a 2D screen displaying the playing area, health, and inventory. The player controls an armored figure that wields a crossbow with a limited supply of bolts that can be replenished by finding more within the dungeon areas. Special "fireballs" can also be launched against foes, although these are limited and are not as common. There are also magical tools and other items that can be collected to provide a variety of benefits such as goblets that can restore health to crystal balls that can annihilate everything on the screen.

The player has to recover the Gemstone, a relic of incredible power forged by the gods and focusing the natural magic of the world. This, they entrusted to Man alone and for a time, there was great prosperity and peace. But the Demons, led by Nicodemius, had managed to boil to the surface and take the Gemstone. Unable to destroy it, Nicodemius fragments it into five pieces and hides them in the Labyrinth, buried deep within the Netherworld. Going into the Netherworld, the protagonist must find and return with the Gemstone.
