Octopus Invasion

Octopus Invasion - Eat all the fish!

Octopus Invasion is an action-packed animal simulation game in which you must level up with a hungry octopus to become the ultimate sea predator.

Dive into the depths of the ocean and take on the role of a small octopus with a big appetite. Hunt fish, improve your skills, complete missions, and unlock new areas on the ocean floor!

How to play

You start this underwater adventure with a small, one-armed octopus searching the ocean floor for snacks in the form of fish, crabs, and other animals. Stalk your prey and catch it with your tentacle like a lasso. As a reward, you'll receive fish bones as currency, which you can exchange at your base station to unlock upgrades.

These upgrades are available to you:

• Catching Speed: The speed at which you catch prey. The more areas you explore in the ocean, the harder it becomes to catch fish. Improve this value if catching takes too long.
• Stomach Capacity: At the beginning, only a few fish will fit in your stomach, but soon you will be able to collect more food. When your stomach is full, you must swim back to your base camp to unload the fish bones.
• Swim Speed: Improve this value to swim faster.
• Tentacle Count: Unlock more tentacles to catch more fish at once.

In the sea, you will encounter various creatures such as a mermaid, a sea monster, or a pirate captain who need your help. Bring them the fish they want and receive bonus rewards for your efforts.

Tip: If you lose your bearings, just look for the arrows displayed near your octopus. The house icon, for example, shows you the way to your base camp.

Can you unlock all areas and become a feared sea predator?
