[p]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![/p][p][/p][h3]
New Combat Boats[/h3][p]This version introduces three new combat boats: [/p][p]
Armed Fishing Boat[/p][p]The armed fishing boat is the most basic type of ship. It can be equipped with one weapon.
![]()
[/p][p]
Armed Speedboat[/p][p]Slightly stronger than the armed fishing boat, it has more upgrade slots and can be equipped with one weapon.
![]()
[/p][p]
Heavily Armored Speedboat[/p][p]Compared to the armed speedboat, it has more durable armor plating, additional upgrade slots, and can be equipped with two weapons.[/p][p][/p][p]
![]()
[/p][p]Since warships are relatively large, they may get stuck on terrain.[/p][p]To address this, a push icon has been added at the bow of the ship, allowing players to push the stuck vessel free.
[/p][p]

Ship-Mounted Weapons[/h3][p]
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As a result, we’ve removed outdated wasteland-era weapons like the explosive crossbow, and only kept machine guns, autocannons, and cannons as usable ship weapons.[/p][p]Among them:[/p]
- [p]The heavy ship-mounted machine gun can be crafted by default.[/p]
- [p]The autocannon and dual machine gun can be unlocked by finding blueprints in the rear crates of captured ships.[/p]
- [p]The quad machine gun, dual autocannon, quad autocannon, and cannon are hidden in high-level combat areas.[/p]
- [p]The CIWS (Close-In Weapon System) is hidden at the airport.[/p]
[p]All of them have unique learning animations, similar to the solar panel and wind turbine.[/p][p][/p][p]

[/p][p]Weapon merchants at trading posts also have a chance to sell blueprints for the dual ship-mounted machine gun and the autocannon.[/p][p]Once learned, these weapons can be crafted at the ship workbench, using the same process as crafting at the gun bench.[/p][p][/p][p]

![]()
[/p][p]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.[/p][p]All ammunition for ship-mounted weapons is crafted in the ammo workshop.[/p][p][/p][p]
![]()
[/p][p]To avoid waste, outdated weapons like the explosive crossbow have been repurposed as defensive structures for players.[/p][p][/p][p]
![]()
[/p][p]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.[/p][p][/p][p]
![]()
[/p][h3]
Ship Repair Platform[/h3][p]
A Tier 4 research station structure that can:[/p]
- [p]Repair damaged ship hulls within a certain range[/p]
- [p]Quickly equip ships located within that range[/p]
[p]
![]()
![]()
[/p][h3]
New Locations[/h3][p]
Airport – Underwater Ruins, Level 4[/p]
- [p]Rich in clay deposits, which can be used to fire bricks[/p]
- [p]It’s very dark underwater, so don’t forget to bring night vision goggles[/p]
[p]
![]()
[/p][p]
Ship Graveyard – Underwater Ruins, Level 5[/p][p]
Enter through a cave to find a massive rocky cavern with a copper vein at the bottom.[/p][p][/p][p]
![]()
[/p][p]Enter from the upper cave opening. Three triangular barrels are placed at the cave entrance as markers.[/p][p][/p][p]
![]()
[/p][p]After passing through a stone corridor you’ll arrive at the mineral pit.[/p][p]
![]()
![]()
[/p][p]Unlike copper ore, mineral veins can be mined infinitely. You’ll need to use a power drill for mining.[/p][p][/p][p]
Iron Ore Locations[/p][p]
New underwater content has been added, including two iron ore veins. Iron ore veins also require a drill for mining.[/p][p][/p][p]
Warehouse[/p][p]
A shipyard has been added to the warehouse, making it easier for players to obtain their first warship: the Armed Fishing Boat.[/p][p][/p][p]
![]()
[/p][p]The shipyard gate needs to be broken open using a melee weapon.[/p][p][/p][p]
![]()
[/p][p]
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).[/p][p][/p][p]
![]()
[/p][p][/p][p]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.[/p][p][/p][p]

New Items[/h3]
- [p]Power Drill: Uses batteries and is used to mine ores or mineral veins[/p]
- [p]Warship Blueprint Item: Can only be obtained by capturing a ship and opening its rear trunk[/p]
- [p]Solar-Powered Welder: Never worry about running out of power while repairing your base or ship again.[/p]
- [p]Warship Blueprint Item: Can only be obtained by capturing a ship and opening its rear trunk.[/p]
- [p]Large Battery: When connected to a circuit, it increases the power output of all generators in that circuit by 25%. (This effect is stackable.)[/p]
- [p]Antenna: When powered, it displays enemy ship routes on the world map.[/p]
[h3]
Other Optimizations[/h3][p]
Auto Oxygen Supply Optimization:[/p][p] When wearing an oxygen tank, an auto-breathing toggle will appear. If turned off, the system will no longer supply oxygen automatically.[/p][p][/p][p]
![]()
[/p][p]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.[/p][p][/p][h3]
Trading Post Changes[/h3][p]
Quick-inflate oxygen bottles are now sold at the trading post — 10 per purchase.[/p][p][/p][p]
![]()
[/p][p]Brick molds have been replaced with clay.[/p][p][/p][p]
![]()
[/p][p][/p][p]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.[/p][h3]
Repair System Improvements[/h3][p]
When holding a repair hammer or welder, damaged buildings will be outlined in red.[/p][p][/p][p]
![]()
[/p][h3]
Nighttime Changes[/h3][p]
We’ve reworked the night lighting effects, making it brighter and easier to play during nighttime.[/p][p][/p][p]
