About This Game

Every Catch Tells a Story

A quiet day at Hidden Pond becomes the beginning of a journey. Join Halley, a cat with a love of fishing and a worn medallion from his father, Elias. Follow a trail of relics across distant waters—and discover how much there was behind the fish stories Halley heard growing up.

Halley’s Big Catch combines peaceful fishing spots with hands-on fish fights, tackle progression, trophy hunting, and a story revealed through your discoveries.

Find Your Next Favorite Fishing Spot

Cast into quiet ponds, mountain creeks, tropical reefs, winding rivers, and the open ocean. Travel across 17 locations, each bringing different fish, conditions, and reasons to return.

Fight the Fish

Set the hook, manage your drag, and control the tension as you reel in your catch. Fish can leap, run, and shake the hook. Timing matters, and the right tackle can make a difficult catch more manageable.

• Time your hook set when a fish takes the bait.

• Adjust your drag and manage line tension during the fight.

• Match your tackle to the fish you’re pursuing.

Build Your Tackle

Earn money from your catches and upgrade your rod-and-reel combo, line, and bait. Match your equipment to the water, from small pond catches to powerful offshore species.

Fill Your Collection

Discover more than 70 fish species, record your biggest catches, and pursue location trophies. Your collection tracks the species you’ve landed and the personal records you’re trying to beat.

Follow Elias’s Trail

Find 12 relics connected to Halley’s father. Watch the medallion react to your discoveries and piece together the clues in your journal. What begins beside a familiar pond reaches far beyond home.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some Steam store and library artwork (capsules, hero, broadcast panels, and similar marketing images) was created with generative AI, then selected and cropped by the developer.

A few 3D props were blocked out with an AI modeling tool and then adjusted by hand for the game.

The game itself does not use generative AI while you play. Halley, the story, fishing, and locations are human-authored. Worlds and water use traditional game systems, not live AI generation.
