Released for the Sega Genesis / Mega Drive in 1994, Monster World IV is an action-adventure game developed by Westone and published by SEGA. It blends action-adventure and adventure elements.

It landed about 5 years into the Genesis's life. Other notable Genesis releases from 1994 include Sonic the Hedgehog 3, Mortal Kombat II and FIFA International Soccer. Among the 18 Genesis action-adventure games in our database, it ranks #2 by legacy score.

It is part of the Wonder Boy series; on the Genesis you can also try Wonder Boy in Monster World and Wonder Boy III: Monster Lair. The series also appears on other systems with Wonder Boy in Monster Land (Master System) and Wonder Boy III: The Dragon's Trap (Master System). Westone also made Turma da Mônica na Terra dos Monstros and Mega Bomberman for the Genesis.

This is a solo experience: one player, no waiting on anyone else.

What playing Monster World IV is like

Action-adventures blend real-time combat with exploration, puzzles and item collection. You open up a larger world gradually as new tools let you reach places you couldn't before.

Tip for newcomers: Keep a mental (or paper) map of locked doors and unreachable ledges; most action-adventures expect you to come back once you find the right item.
