Super casual on-hook gameplay!

Place your turret in the deep sea, destroy the mutant fish on the seabed, and get a lot of crystals.
Enemies will become stronger and stronger, and terrible bosses will appear. You must buy turrets with crystals and synthesize them to obtain more advanced turrets.
At the same time, don’t forget to upgrade your turret attributes and trenches to increase your combat effectiveness!
In addition, there are powerful group skills such as lightning and freezing, which will greatly help you in the battle. Please don't be stingy with them and give a fatal blow to the enemy!
