Update v0.7.02 | Public Test Branch

Naval Combat Content

This version introduces 2 warships:

Armed Ferry

The armed ferry is a cargo vessel equipped with 1 forward cannon slot and 1 machine gun slot on the second deck.

The armed ferry has the following features:

• Two storage crates

• The second deck comes with an advanced water purifier

• Relatively slow speed

Heavy Firepower Armed Speedboat

Equipped with 1 forward cannon slot and 2 machine gun slots, this armed speedboat is currently the only warship with three weapon slots.

Ship-Mounted Weapons

New Weapon: Ship-Mounted Anti-Aircraft Gun – can only be equipped in cannon slots.

Learnable at The Ruins Island.

New Building

An aquarium – a place to display your collected ornamental fish, which will swim freely inside. You can also plant red algae at the bottom.

The aquarium is made up of three parts:

• Base

• Extension Section (Aquarium)

• Entrance Gate

Players can freely enter and exit the aquarium through the gate (the aquarium is equipped with advanced oxygen supply technology, so there’s no need to worry about oxygen).

There is a control panel on the front of the aquarium that can be interacted with to open the aquarium interface.

Once opened, you can transfer ornamental fish from your backpack into the aquarium.

Of course, ornamental fish are still fish… so you can grill and eat them too.

New Ornamental Fish

We've added a total of 30 new types of ornamental fish, scattered across various locations on the map — for example, near the mansion close to Drifter's Island.

How to Catch Ornamental Fish? These little fish aren’t very fast — just get close and catch them with your hands!

It’s worth noting that there is one special fish: the Discus Fish. These color-mutated Discus Fish cannot be found in the wild — they can only be obtained by trading a juvenile Discus Fish with the Contract Merchant.

Other Optimizations
