BigHero.io is a hilarious battle arena game in which your character is armed with a giant battle axe, studded bat, sword, or some other deadly weapon with a long reach. Make your way through the arena and twist around to put other players in your range of attack. Swing your weapon and reduce them to a big splat on the floor while you rake up the points. Search for slimes to kill for additional points, and power-ups to boost your speed. If you get into trouble, you can hit D for a short sprint that will help you get away quickly.
