8 Eyes

Set in the distant future after a nuclear war, the Great King has used eight magical jewels called "Eyes" to rebuild the planet. After the king's eight dukes each steal an Eye to gain control of the world, it's up to you, Orin the Falconer, to save the day. Along with your trusty falcon Cutrus, you must infiltrate each of the duke's castles and retrieve the 8 Eyes. When you defeat a duke, you are awarded a more powerful sword to be used against one of the remaining dukes.
