Sydney Shark

You guide the shark through the water using the arrow keys, moving it up and down to chase after swimmers and boats. Pressing a key makes the shark bite, which is your main way of interacting with everything. The objective is to cause as much chaos as you can, attacking anything that moves on or above the water. You can even leap from the sea to bring down helicopters, which usually results in a satisfying explosion. The game moves quickly, and the difficulty comes from managing your attacks while avoiding counter-fire from the police and military. It feels like a controlled frenzy of destruction.
