"15 Defense. Underwater Battle" This game gets you plunged into a tough fight on the bottom of some imaginary sea. Octopuses, piranhas and shark attacks won't leave you a spare sec! Move your jellyfishes and charge them to defend your small 4x4-cell kingdom. Counteract: freeze your enemies, sniper-shoot them and run away from their agression. Collect pearls, get money and upgrade your skills and talents to boost up your attacks and survival time.
