Play Battle Shark Online

Battle Shark came out in 1989 as an arcade game from Taito. It was part of that wave of periscope-style shooters where you physically lean into a cabinet to aim. The game puts you in a submarine, tasked with defending against an endless naval assault. It doesn't try to be anything more than a straightforward test of reflexes.

You control a crosshair, firing torpedoes and depth charges at enemy ships and aircraft that scroll into view. The main objective is to survive each timed stage by destroying everything that moves before it can sink you. The signature mechanics involve switching between two weapon types for surface and underwater targets, managing a limited supply of special weapons, and timing shots against fast-moving planes. The pacing is relentless; the difficulty spikes quickly, demanding constant attention. It feels like a desperate, claustrophobic fight against an overwhelming force.
