Big Helmet Heroes is a 3D beat’em up where players control armored knights who set off on a journey through a variety of locations. Each stage offers action-packed battles that force players to use a combination of attacks, dodges, and special moves. There is also a co-op mode that allows two users to team up and go through the adventure together. As the story progresses, the main characters set off on a mission to rescue a kidnapped princess. Along the way, they encounter waves of enemies, each with their own abilities and attacks.
