Gunball 2: The Emperor’s Revenge is a sequel to the Gunball Arena. You are a customizable ball that can possess various cannons, swords and equipment. These items are not free, so you need to make money from battles. Destroy the enemy balls and collect the coins that will be added to your bank if you win the battle. Equipment can be purchased at the store or earned by defeating bosses. In addition to earning money and items, you will also gain experience, and when you level up, you will get points to spend on skills.
