Bubble Tanks Tower Defense

Do you remember the amazing game called Bubble Tanks? Here you get into more strategic mood. You build defensive structures in the same design style. You have to cover whole map and prevent the enemies in getting to the other side. Some enemies are normal solid but some can fly and worst are ghosts. Interesting is the design of the levels and improvements and upgrades of your towers. Higher difficulty means more difficult maps and enemies. Nice graphic and extreme gamplay.
