Monster World was once a peaceful region. Then, the peace was shattered by an invading army of monsters. A young man named Shion vowed to defeat them and make his land peaceful again.
Wonder Boy In Monster World is the third game in the Monster World series, originally known as Wonder Boy 5: Monster World 3 . It puts the player in control of Shion in his quest to save Monster World from the evil hands of BioMeka. The gameplay involves running, jumping, and killing enemies.
The game has light RPG elements such as talking to townsfolk, collecting money to buy items, upgrading your life, and equipping a variety of armor and weapons. The gameplay is similar to classic platformers like Zelda. You can save your game at any time to continue your quest.
Wonder Boy In Monster World was released for the Sega Master System in 1987.
