Plunge into the underwater world. The glory of these river predators is truly black - river killers, bloodthirsty robbers, river hyenas, sharks. And she's always hungry. She has to hunt for very fast fish and very secretive, who are hiding at the bottom of the sea, in the thickets of algae. But they still need to get to swim hard-to-reach places, which may also be lurking danger. Sea monsters will want to eat your fish and will hunt for it. So try to stay away from them. When you eat other fish, it accumulates rage, which will give an advantage in the passage of the joint game. Four players can participate in the co-op mode. Whoever creates the game automatically becomes a piranha. To win in multiplayer piranha should not give the fish to find the key. The fish themselves, that would have to win to find the key and stand for some time near him. Good luck everyone !!!
