The world is under the tyrannical rule of the Dark Fiend and his powerful magic. Only one man dares to gather all three pieces of the legendary Demon Sword, the only weapon that can slay the evil one. His name is Victar.
In Demon Sword, you control Victar as you fight your way through several stages on your way to stopping the Dark Fiend. You have a mighty sword at your disposal as well as powerful throwing darts. There are also several magical items to help you out. There are three two-level worlds to play through, as well as an additional level, featuring the final battle with the Dark Fiend. But in order to defeat him, you must first defeat the other three bosses and reconstruct the Demon Sword.
