Bubble Tanks 2

With a whole host of different tanks to offer, Bubble Tanks 2 is a brilliantly expansive game which will leave you playing for hours. Not only are there well over two dozen tanks you can upgrade to yourself, each one has multiple stages of development as you gather bubbles from fallen enemies to build up your own strength. With a powerful boss creature to defeat, you'll find yourself playing the whole game again just to take a different upgrade path as you say to yourself "what if I went for the heavy tank route instead of the agile fighter..."
