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

System Changes

• Added specific HDRP assets (render quality profiles) for the three quality levels: High, Medium, and Low. You can select them in the game settings.

• Helicopters can now be pushed.

Bug Fixes

• Fixed issues where graphic settings, network information, and tutorial toggles could not be saved or loaded.

• Fixed certain graphics settings not applying properly.

• Fixed an issue where selecting a graphics quality preset would reset the field of view (FOV).

• Fixed an issue where items could not be added to the wishlist or displayed incorrectly.

• Fixed a bug where adding items to the wishlist would cause them to be automatically hidden.

• Chainsaw can now be used underwater.

• Fixed an issue where certain guns could not be crafted due to their model being unselectable on the gun bench.

• Fixed a problem where some triangular structures could not be rotated during construction.

• Fixed an issue where ships would continue to rotate or drift after stopping.

• Fixed a bug where pressing a shortcut key (e.g., [B] for build menu) while naming a ship would open the corresponding UI.

• Ships can no longer be pushed while they are running.

• Removed collision damage from the player’s own ships and aircraft.

• Fixed an issue where base defense equipment (e.g., explosive crossbows) could not be reloaded.

• Fixed a bug where coastal defense weapons remained even after the message “enemy has escaped” was displayed.

• Fixed an issue where enemy ships would still spawn inside an outpost even after it was captured.

Naval Combat Update v0.7.01 | Public Test Branch

Hello Sunkenlanders! Thank you for your continued support and patience as we worked on this new update. It’s now live on the public test branch, and we’re excited to introduce a range of new content, improvements, and optimizations — including naval combat, new warships, underwater locations, and ship-mounted weapons. Let’s dive in!

New Combat Boats

This version introduces three new combat boats:

Armed Fishing Boat

The armed fishing boat is the most basic type of ship. It can be equipped with one weapon.

Armed Speedboat

Slightly stronger than the armed fishing boat, it has more upgrade slots and can be equipped with one weapon.

Heavily Armored Speedboat

Compared to the armed speedboat, it has more durable armor plating, additional upgrade slots, and can be equipped with two weapons.

Since warships are relatively large, they may get stuck on terrain.

To address this, a push icon has been added at the bow of the ship, allowing players to push the stuck vessel free.

Ship-Mounted Weapons

Based on testing, since naval battles involve dynamic, moving targets attacking each other, only modern, fast-firing weapons are effective.As a result, we’ve removed outdated wasteland-era weapons like the explosive crossbow, and only kept machine guns, autocannons, and cannons as usable ship weapons.

Among them:

• The heavy ship-mounted machine gun can be crafted by default.

• The autocannon and dual machine gun can be unlocked by finding blueprints in the rear crates of captured ships.

• The quad machine gun, dual autocannon, quad autocannon, and cannon are hidden in high-level combat areas.

• The CIWS (Close-In Weapon System) is hidden at the airport.

  
  

All of them have unique learning animations, similar to the solar panel and wind turbine.

Weapon merchants at trading posts also have a chance to sell blueprints for the dual ship-mounted machine gun and the autocannon.

Once learned, these weapons can be crafted at the ship workbench, using the same process as crafting at the gun bench.

To maintain portability, unequipped ship-mounted weapons will not be placed in the player’s backpack. Instead, they are stored in a virtual ship inventory, so they don’t take up any inventory slots. Players can simply equip or unequip them through the interface.

All ammunition for ship-mounted weapons is crafted in the ammo workshop.

To avoid waste, outdated weapons like the explosive crossbow have been repurposed as defensive structures for players.

Except for the nail gun turret, all of these are blueprint-based structures, and each type of ammunition is crafted at the black powder gun station. The nail gun turret is a Tier 2 research station structure that fires crossbow bolts.

Ship Repair Platform

A Tier 4 research station structure that can:

• Repair damaged ship hulls within a certain range

• Quickly equip ships located within that range

New Locations

Airport – Underwater Ruins, Level 4

• Rich in clay deposits, which can be used to fire bricks

• It’s very dark underwater, so don’t forget to bring night vision goggles

Ship Graveyard – Underwater Ruins, Level 5

Enter through a cave to find a massive rocky cavern with a copper vein at the bottom.

Enter from the upper cave opening. Three triangular barrels are placed at the cave entrance as markers.

After passing through a stone corridor you’ll arrive at the mineral pit.

Unlike copper ore, mineral veins can be mined infinitely. You’ll need to use a power drill for mining.

Iron Ore Locations

New underwater content has been added, including two iron ore veins. Iron ore veins also require a drill for mining.

Warehouse

A shipyard has been added to the warehouse, making it easier for players to obtain their first warship: the Armed Fishing Boat.

The shipyard gate needs to be broken open using a melee weapon.

Zion Atoll has also been updated. A starter fishing boat is now available for new players(with a small chance of spawning an armed speedboat, as shown in the image).

Some Level 4 and higher combat zones now feature coastal defense turrets. You can destroy them by eliminating their operators. The best option is to use ship-mounted weapons, but you’re free to use sniper rifles or other weapons as well.

New Items

• Power Drill: Uses batteries and is used to mine ores or mineral veins

• Warship Blueprint Item: Can only be obtained by capturing a ship and opening its rear trunk

• Solar-Powered Welder: Never worry about running out of power while repairing your base or ship again.

• Warship Blueprint Item: Can only be obtained by capturing a ship and opening its rear trunk.

• Large Battery: When connected to a circuit, it increases the power output of all generators in that circuit by 25%. (This effect is stackable.)

• Antenna: When powered, it displays enemy ship routes on the world map.

Other Optimizations

Auto Oxygen Supply Optimization:

When wearing an oxygen tank, an auto-breathing toggle will appear. If turned off, the system will no longer supply oxygen automatically.

When diving with an oxygen tank equipped, a white line will appear on the breath bar, indicating the auto-breath threshold. If auto-breathing is turned off, the white line will turn gray.

Trading Post Changes

Quick-inflate oxygen bottles are now sold at the trading post — 10 per purchase.

Brick molds have been replaced with clay.

Clay can now be found along coastlines and sea floors, with high concentrations in areas like the airport, Small Stone Island, and the warehouse.Now, 5 clay can be smelted into 5 bricks.

Repair System Improvements

When holding a repair hammer or welder, damaged buildings will be outlined in red.

Nighttime Changes

We’ve reworked the night lighting effects, making it brighter and easier to play during nighttime.
