Monster Force is an action-packed adventure game set in a world where monsters from classic Universal movies have come to life. The story follows the evil plans of these creatures as they wreak havoc on human cities. Players must take control of one of four heroes - Dracula, Frankenstein's monster, the Mummy, or Wolf Boy - and navigate through increasingly challenging levels to stop the monsters' evil schemes.
Gameplay is fast-paced and action-packed, with players controlling their chosen hero as they run around, hit switches, shoot bad guys, and try to avoid taking damage. Timed challenges and boss battles add an extra layer of difficulty and excitement to the game. The GBA's multiplayer mode also allows for friendly competition with friends.
