Boom.io is also a multiplayer game where you become a hero with a ball mace. Your task is to walk through the game area and collect colored balls which enlarge the ball at the end of the ball mace. It really helps you, because the larger the area, the more chance you have to hit the opponent. Kill as many enemies as possible and achieve the best score. Controls are very simple. Use only the mouse to move and left mouse button to release the ball and throw it at the enemy. Walk through the entire playground, fight for glory in the arena and become the master that controls a historical weapon. Have fun.
