Lord of the Sword (ロード オブ ソード, "Lord of Sword") is side scrolling action-adventure video game for the Sega Master System. The game is based in a medieval fantasy setting.

Landau is armed with a sword for close combat and a bow for ranged combat. The Kingdom of Baljinya has towns and villages where Landau can stop to rest (restoring his health) and gather information from the people. There are also castles which can only be entered after completing certain tasks. Each time the player has the opportunity to speak with a character, he should talk with the character several times in succession in order to get all possible messages. If he does not get all possible messages, bosses and secret paths in the game will not appear. If something doesn't appear for the player, he will most likely need to speak with a character, or speak with a character additional times. There are different kinds of terrains between those villages, towns and castles. Flatlands, dark forests, mountains and swamps make up the rest of the landscape.

Those terrains are plagued by different kinds of monsters, some specific of each terrain. If killed, the player has up to ten continues to complete the quests. When faced with a boss monster, the player will need to hit its weak point or at its weak moment. Often when a boss monster is destroyed, Landau is rewarded with a better sword or better bow which deals more damage.
