Cast your line into the depths.

Deep Fishing is a fishing adventure set around mysterious underground lakes.

The deeper you descend, the less your catches resemble ordinary fish.

Catch strange creatures, collect sealed treasure chests, and decide whether to push deeper for greater rewards or return to base with everything you've earned.

The deeper you go, the stranger it gets

Explore underground lakes, fungal waterways, and crystal-filled geothermal caverns.

Each layer has its own atmosphere, creatures, and dangers, with powerful bosses waiting at the deepest points.

You won't know what's inside a chest until you make it back

Successful catches can reward you with treasure chests of different rarities.

Their contents remain unknown until you safely return to base and open them.

Going deeper means more chances to bring home a huge haul, but failure will cost you part of what you've collected.

Do you return now and secure everything?

Or risk one more layer for a better reward?

Upgrade your fishing gear and descend even further

Use gold and the rewards you bring back to improve your ROD, REEL, and LINE.

Creatures that once pushed your equipment to its limits become more manageable as you grow stronger.

Fish. Return. Grow stronger. Go deeper.

Follow the traces of your missing brother

One reason the protagonist continues descending is the disappearance of his older brother.

Strange clues and increasingly unnatural phenomena await below.

Something unknown lies deep beneath the underground lakes.
