Koop Scale the Depths - SteamScale the Depths - Steam

A dopamine-boosting gameplay loop

Catching fish is only the beginning.

Cast your line, hunt for the perfect catch, scale it with care, serve it to hungry customers, and turn your hard-earned cash into better gear. Then go deeper. Catch stranger fish. Make more money. Upgrade again.

You know, just one more run.

Each improvement pushes you further into the depths… and further from whatever counts as normal.

Various locations, plenty of surprises

Explore four distinct fishing spots inspired by real places – from Loch Ness to Outer Banks, Point Nemo, and beyond.

Each location comes with its own:

1. 
   

   atmosphere and environment

   
   


2. 
   

   gear

   
   


3. 
   

   fish species

   
   


4. 
   

   hidden paths and secrets

   
   


5. 
   

   puzzles, treasures, and strange things waiting below

   
   

The deeper you go, the less this feels like a simple fishing job.

Unexpected customers with individual tastes (and options)

Your customers are not human. Some are cute. Some are mythical. Some are exactly the kind of creatures you wouldn’t expect to order dinner from a tiny robot on a boat.

Serve wild animals like otters, axolotls, and herons, alongside beings inspired by myth and folklore, including legends such as Nessie and Kelpie. Each customer has their own personality, appetite, and favorite fish.

Learn who likes what, deliver the right catch, and you might earn a very generous tip. Serve badly, and… well, they’ll have opinions.

Secret & treasures

There’s more than fish hiding underwater, and definitely more lore than anyone reasonably expects from a game about fishing.

Search the depths for:

1. 
   

   hidden treasures and collectible artifacts

   
   


2. 
   

   messages in bottles

   
   


3. 
   

   secret passages

   
   


4. 
   

   environmental puzzles and levers

   
   

Every scrap of old notes and logs brings you a little closer to understanding why this tiny robot is busy fishing in the first place.

Customize your boat & fish in style

Progress isn’t just about bigger numbers (although bigger numbers are very nice).

Upgrade your fishing gear, unlock better tools, customize your boat, and dress up your tiny robot fishmonger before sending them back into increasingly strange waters.

1. 
   

   Improve your rods, hooks, bags and scaling tools

   
   


2. 
   

   Unlock new boats and cosmetics

   
   


3. 
   

   Scale tiny fish with increasingly ridiculous tools

   
   


4. 
   

   Look good while feeding ancient beings from the deep

   
   

Because if you’re going to prepare fish for strange creatures, you might as well do it in style.
