unique gameplay in a relaxing underwater environment
Fish involves the player exploring and navigating the 3-D world, while talking to NPCs to advance the story and perform missions - usually of the fetch quest variety.

The fish must eat other sea life to stay strong and healthy, this is done by biting onto the "enemy" and then wiggling the right control stick to tire the smaller creature out, and then it can be swallowed.
Sometimes, though, what looks like a delicious sea creature is actually a fisherman's lure, and once hooked the fish must fight by swimming fiercely and jumping from the water to break the line. When a fisherman's line is broken the lure will be added to somewhat of a "trophy" collection.

All in all, delightful fun, and gameplay unlike any other.
