Killer Whale is an action game where you control a dangerous killer whale. Right at the beginning, you can choose which mode to play. There is Ocean King mode, where you have to go through all the levels. In each you will have a task, for example to kill several fish of a certain species. Another mode is Survival, where you will have a single goal, eat other fish and try to survive as long as possible. The last mode is Exploration, in which you will just swim around and discover the water world around you.
