About Fish Idle 2 Underwater Mystery

Crush in your rainboots and hop into your boat! We are going fishing in Fish Idle 2: Underwater Mystery, a unique idle fishing arcade featuring smooth graphics and intuitive mechanics. We have no time to swing a fishing rod, so let’s streamline the process!

SIMPLE AND EASY FISHING

Let’s start with the basics. It’s all about automation: fish start biting as soon as you approach them, and resource indicators keep you informed while you focus on managing your Fish Kingdom effectively. The game offers advantageous upgrades to enhance your idle fishing abilities, helping you become a true fish tycoon. You’ll still need to steer your boat to chase fish schools and avoid obstacles, so don’t get too distracted by your economic prowess!

UPGRADE YOUR FISH KINGDOM

Once your hull is full, it’s time to get upgraded! Improvements in fishing speed let you catch more and rarer species, while increased storage capacity allows you to hold more catches in your boat. Boost your boat’s speed and defense for impact protection, and enhance your fishing rods to cast multiple lines at once. It’s all about maximizing your gains in the most efficient way, so you’ll have to use your head to figure out the best way to success!

MAKE IT BIG

Just like in real life, becoming a fish tycoon involves various ways to profit from your catches. The Idle Fish Farm allows you to invest and get passive income, while the Black Market lets you upgrade your Fish Kingdoms beyond OSHA standards. The Bots Shop enables you to hire hunter, fisher, and cargo ships to fish and deliver catch for you, boosting your income. If day trading is your thing, there is a Currency Exchange that has some special benefits. Tax fraud is not a crime, it’s an obligation if you want to make it big.

NOW GO FISH

Get ready to dive into the Fish Kingdoms and become the ultimate fish tycoon in Fish Idle 2: Underwater Mystery!

Information about Fish Idle 2: Underwater Mystery for PC

Fish Idle 2: Underwater Mystery is an arcade fishing game where fun and management combine to offer a unique and simple experience. Instead of traditional fishing, this game streamlines the process, allowing fish to automatically approach the player. Thus, the focus is on the efficient management of a “Fish Kingdom”, where the goal is to maximize catches and profits while sailing and managing resources.

As the boat fills with fish, the player can invest in upgrades to increase storage capacity, catch rarer species, or protect their vessel. Upgrades also include increasing the boat’s speed and defense, as well as upgrading fishing rods to cast multiple lines, thus optimizing fishing performance and efficiency on each expedition.

The game incorporates a complex internal economy where income does not only depend on direct fishing. Players can invest in their Idle Fish Farm to generate passive income, trade on the black market to maximize profits, or employ bots for specific tasks, further increasing their income. There's also a currency exchange system that offers additional benefits, and even the option to practice dubious economic strategies to increase profits.

The goal is to become a fishing tycoon, using economic strategies and making smart decisions in every aspect of the game. Fish Idle 2 combines arcade and management simulation elements with a touch of humor and creativity, allowing you to build an underwater empire and achieve success.

Additional options to buy this game on Steam

In practice, a €50 Steam Gift Card is usually enough to buy most games currently available on Steam. It is redeemed via a digital code, works with all PC games on Steam, and is a common alternative for purchasing games without entering payment details.
