Stormworks Patch 1.5 Notes – June 2, 2022

Underwater Biome

The new biome includes a series of volcanic islands, based on many of the volcanic islands in the Pacific Ring of Fire. Many of these new islands are active volcanoes and can erupt at random or on request from the custom menu.

The biome also includes new under-sea features, including a trench, sea floor cabling, ruins, wrecks, and many kilometers of winding an interlinked underwater tunnels. The tunnels can be accessed from underwater, and also new caves on some islands.


There are many new locations, named in honour of great community members and workshop creators. Thank you to the selfless and kind people who give up their time to help other players, and thank you to the talented creators who have reached high popularity with incredible creations on the workshop. There are many more community heroes and creators than we have had chance to honour, and look forward to naming more locations in the future.

Underwater Missions

There are several new mission types, including submersed rescues, salvage, and repairs. These missions can spawn in many locations across the world, as well as specific new locations in the new biome.


It is now easier to see underwater as we have increased visibility and lighting, to help with underwater operations.

Glow Sticks

To help keep track of locations and add some softer illumination at night or underwater, we have added new glow sticks! The color of the glowsticks can be painted in the editor, and they will last a long time when deployed.



We have added new sonar components, that behave in a more realistic manner. Sonar can now listen in all directions at once, and can operate in active and passive mode. In active mode, the sonar emits a loud ping which travels far through water, bouncing back off vehicles and other objects with a delay relative to the distance travelled. Passive sonar simply listens and can detect propellers, engines, and other noisy parts.

Changes that include a #NUMBER relate to fixes or features submitted by the Stormworks community via ‘’ which can be accessed via the ‘Report Bug/Request Feature’ button in-game.
Posting a submission to this tracker ensures we review your suggestion/report since we may not see reports submitted via other channels.


While we made no infrastructure changes in this update we still recommend creating a new save file as various new environment zones have been added to the default scripts to allow the new mission types to spawn.

Feature – New Volcanic Archipelago biome (#5171 #879 #2019)
Feature – New underwater themed missions and mission improvements
Feature – New Glowstick Equipment (#801)
Feature – Advanced Sonars and Sonar Jammer (#337)

The new 40x40km volcanic archipelago biome is located south-west of the sawyer isles and is the new home of the Kraken.
The region features a series of small volcanoes interspersed with deep trenches, sunken landmarks and an intricate network of submerged passages.


With the addition of several underwater themed mission scenarios we also made various fixes and improvements to the existing mission infrastructure.
Missions should now have an easier time spawning as some theme filtering was previously limiting mission spawning too strictly, meaning some mission scenarios were previously unable to spawn successfully.
The Repair mission objective has been expanded in functionality to several mission types; players can expect to require an underwater welder for some of the new missions, with search-and-rescue missions sometimes offering an optional reward for repairing the vehicle in distress.
