Bubble Tanks 2
Bubble Tanks 2 adds some new features while keeping the basic gameplay. You are still a tank, who wants to be the most powerful one. Travel from bubble to bubble, destroy other tanks, and collect their bubbles to make your tank stronger. Now, there are tank ranks, so you need to collect a certain number of bubbles to achieve a certain tank. Battle basic tanks or ones that are fearsome and would love to destroy you. Rule the Bubble world!
