StormWorks News & Announcements

Dear Stormworkers,

In this minor update, we are adding a new size of tank tracks between the small and medium sizes. These tracks will be 2 blocks wide, which has been frequently requested by tracked vehicle creators who are struggling to get the look they are going for, because the 1-wide tracks were too narrow, and the 3-wide tracks too wide. These new tracks otherwise work just like the others!

We have also been continuing to look at multiplayer. A popular request is for servers with players on to be sorted to the top of the list. This makes it much easier to find servers with players already on. We have also been looking at a rare issue where some players found themselves such in place and unable to move in multiplayer. We have made some improvements to this, and it should be resolved for most users.

This update also contains the usual bug fixes and improvements. Please see the full patch notes below.

Thanks to all the players giving great feedback on potential audio changes! We have been planning many of these suggested changes, and they should make for some great minor updates.

Much love <3,

The Stormworks Developers

Dear Stormworkers,

This week is announcement week, with a minor update due for release next week!

We are working hard to improve Stormworks in many directions! Some of these directions are less interesting to talk about in an announcement, such as fixing crashes and digging through netcode, while more cosmetic changes tend to be easier to write about.

One such direction we are exploring is improvements to audio! For a long time, players have been asking for improvements to various sound effects, and asking for new sound effects where audio would be useful feedback. For the last 8 years we have been lucky enough to work with Chris Randle and Jon Daou across various games.

For sound effects it has worked best in the past to order in batches, but for Stormworks we have frequently found ourselves needing sound effects on a weekly basis for a new component or interaction. This has encouraged reuse of SFX, or missing SFX out, and there are many places where we would want to improve.

Instead of ordering in batches, we will now be having a sound engineer work weekly with the team to improve all these missing and borrowed sounds, but also work creatively on the sound design. We hope this will bring a big improvement of quality of audio over the coming months, and we will be looking to players to let us know where they think we should start, and where the highest priorities are in terms of improving audio.

In the mean time, we will also be getting on with all the various fixes and improvements, minor updates (including new frequently requested components), major updates, potential new DLC, and more.

We look forward to your audio ideas!

Much love <3,

The Stormworks Developers

Dear Stormworkers,

In this update, we add 4 new outfits: light, medium and heavy body armour, and bomb disposal. If you have the Weapons DLC enabled, these outfits give additional ballistic protection from small calibre rounds, or in the case of the bomb disposal outfit, explosions!

Many players have been asking for Weapons DLC updates, and we are really excited to bring this new update. Even if you don't have the DLC, these new outfits are still available with cosmetic only function.

We are also adding several important bug fixes and improvements, please see the patch notes below for full details.

As always, we are continuing to work on more fixes and imrpovements, minor updates, and major updates! The next few minor updates will include new components and we will announce more soon!

We look forward to hearing your thoughts and feedback on the new update!

Much love <3,

Feature - Functional Weapons Outfits (#7960 #3217)

In this update we have added 5 new outfits that protect the player against projectile and explosive damage at the expense of slowing down the player's movement speed.
Most of the new outfits include a helmet which will additionally reduce headshot damage.

Fix - #11746 Speargun inventory spelling error
Fix - #11805 #11754 Leaks now occur for voxels that take more than 1 damage in a single instance

Dear Stormworkers,

In this announcement post, we discuss next weeks minor update including new weapons outfits, as well as other upcoming minor updates and major updates.

Next week we are releasing new outfits! These outfits spawn in inventory boxes in a similar way to scuba, firefighting, etc. outfits. While they are available in the base game, they only function cosmetically. With Weapons DLC enabled, these outfits provide enhanced ballistic protection.

The new outfits include various grades of body armour / helmets, as well as a bomb disposal outfit with protection specifically to explosives.

Of course there will be more than just these new features, and many fixes and improvements will also be included in next weeks update.

We are getting further ahead with our updates, and have managed to extend our lead-in time (the time between completing or near-completing an update, and releasing it). This is giving us more time for quality control and testing, and is generally just a calmer way of working. This also means we are working on various minor and major updates at any one time!

We previously discussed a new major update that we have been working on, that we would like to extend and expand into a much bigger DLC update. We are still considering this and working on other new features that are related and could become part of this, if not their own update.

We are also working on other major update features, and while it is too early to talk about specifics, there is a lot of really fun and interesting stuff that can add a lot to the life of the world of Stormworks.

Dear Stormworkers,

This week we add the new steam piston and steam whistle components!

The new steam pistons come in various sizes. As discussed last week, the steam pistons are designed to work with a similar mechanic to real steam pistons, where the difference in pressure on each side of the piston pushes the piston from end to end. There are 2 ports on each side of the piston, and the valves for these ports are driven by the crank rotation.

Try out the new steam tractor preset, or design your own steam engine! Simply supply high pressure steam to the input ports, and allow the steam to exhaust by adding exhausts or steam whistles to the output ports.

As the crank rotates, the torque acting on the crank varies. The pistons are most efficient mid-stroke, while at the ends of the stroke, the pistons do not apply force efficiently, creating dead zones. To counter-act this, placing pistons next to each other links their crank shafts, and you can offset their crank offset in the properties.

The new steam whistles are similar to output ports, except with the flow of steam, they produce a whistling sound! You can play around with the pitch in the whistles properties so you can customize the tone of your whistle, or just serenade your friends with a musical steam organ creation.

These components have requested ever since the steam and nuclear major update! So we are very excited to bring this update to players.

There is plenty more in this update, so be sure to read the patch notes below for info on all the fixes and improvements included in this minor update.

Much love <3,

Dear Stormworkers,

It is announcement week, with an update being released last week and one planned for next week!

Next weeks minor update includes several new components that many players have asked for over a long period of time for various reasons!

One component being released next week is the new steam piston! Players have been asking for other ways to make steam engines, including smaller engines for some time and this new update will do this. The new steam pistons come in various sizes, and are designed for low-speed high-torque applications.

The steam pistons work in a very mechanical way, similar to real steam pistons. There are 4 steam ports on each piston cylinder, with 2 ports above the piston head, and 2 below. There is also a connecting rod and a crank shaft that rotates in the expected way. The valves opening and closing each port are controlled by the position of the crank shaft. A typical way to use this new component would be to supply high pressure steam to the input ports, and add exhausts to the output ports.

In one direction of the stroke, the piston will open the input valve of the compressed side of the piston, and the output valve of the expanded side. The difference in pressure between the two side of the piston will create torque and motion. As the piston reaches the other end of the cylinder, the valves reverse, exhausting the high pressure steam, and allowing high pressure steam into the other side.

Like a real steam engine, either a flywheel or multiple out-of-phase pistons are advisable to avoid stalling. This is because the torque action on the crank shaft has low-efficiency zones at the ends of the strokes, just like real pistons. Adjacent pistons placed next to each other are locked together, but can be spawned with player-defined crank cycle offsets. This allows a huge amount of control over how engines are built.

Along with steam pistons, there are several other related components that we will announce next week! And of course, there will be the usual bug fixes and improvements!

Dear Stormworkers,

In this weeks update, we have re-engineered train signals so that they are an add-on rather than being baked into the world.

The implications of this is that train signals can be replaced with an add-on. This is something that the train community has been asking for, for a long time. It means that different styles of signals can be used, as well as mechanically different signals that follow different logic, unlocking the potential for automation and other mechanics.

This update is of course, a minor step in expanding what can be done with modding. While the headline might be "train signals", the majority of this update is actually bug fixes, as we continue to work through all the issues and defects in the game, and tighten up the quality of experience. While plenty remains to be done, we have made huge progress so far this year, as we have rebalanced our time and processes to avoid adding new issues, while clearing out the backlog of existing problems. While it can be difficult to measure from playing the game, we are counting the issues, and only a fraction remains compared to how the year started out.

There are many different ways to play Stormworks, and we want to make all players happy, so the minor updates focus on different areas as rotate our focus around the different Stormworks communities. This can cause friction in the comments section.

Our advice is not to take the comments too seriously. We make an active effort to count and measure players requests, and we won't count one opinion over another. To the vast majority of players giving calm, constructive, and valued feedback, thank you. We do our best to be fair with our release plans, and while everyone may not benefit from this weeks headline as we show some love for the trains community, hopefully all will notice benefit from the fixes, and all will enjoy something more relevant to their community in the next few updates.

Please see below for the patch notes with the full list of fixes and improvements.

Much love <3,

Dear Stormworkers,

This week is announcement week where we discuss our development plans and release new information. There are no huge announcements this week so we will keep it brief.

The Steam Summer Sale is now on, and for the first time in Stormworks history, we are in the sale! Stormworks is currently 30% off, and 20% off for the DLC.

Next week we have a new minor update planned with many fixes, and some reworks, including replacing some existing game content with add-on content to make the game a little bit more moddable. More info on this next week with the release!

While we are testing next weeks minor update, we are also adding the finishing touches to the following one. In the following minor update, we plan to add some new equipable outfits! These are new outfits that fit in inventory boxes in a similar way to scuba / diving / firefighting, except with a different function.

Other projects in progress is the next major update which is looking awesome but sadly not due for release for a few months, and some technology tests for the new game engine that we are working on. We are having a lot of fun working on all these new updates and improvements and there is a lot for players to look forward to over the rest of the year and beyond.

Catch you next week for the minor update!

Much love <3,

The Stormworks Developers

Dear Stormworkers,

In this weeks minor update, we are adding the new vehicle mounted welders and end-effectors, designed for use with autonomous and unmanned vehicles, and manned submarines.

The new welder is an electric type welder and works underwater. As you may expect, when active it repairs any damaged blocks immediately in front of it.

The end-effector component can interact with any button immediately in front of it, as well as interacting with doors.

With the combination of these 2 new parts, players can now achieve a great many tasks previously requiring manual operation. This can be particularly useful when in hazardous or hostile environments such as high temperature, deep under water, or around radioactive materials.

As well as these new components, there are many important bug fixes and improvements. Please see the full changelog below for full details.

We look forward to reading your feedback, and seeing what players create and get up to with the new components!

Much love <3,

The Stormworks Developers

Dear Stormworkers,

This week is an announcement week, with the new major update launching last week, and we have a minor update planned for next week including 2 new components and loads of fixes!

Next weeks update includes 2 new components for performing tasks normally performed manually - with a vehicle. We are adding a new welder component that can repair vehicles, and a new interaction component that can press buttons and open doors. This enables players to create remote operated vehicles that can perform repair and maintenance tasks. These new components are in response to the fantastic player feedback we have received about the new underwater update, and they will go a long way to giving new functionality and purpose to ROVs.

Our development plans continue as normal, with several minor updates in the works. The next few minor updates include new features, many of which are interesting new components. As always, we prefer to share info only once the update is ready to avoid disappointment. We look forward to releasing this new minor updates to the usual schedule, which is every 2 weeks.

We have also been working on several big updates, which we expect to release as major updates or over time as minor updates. One update in particular is coming together really well, and we are getting really excited about other ways we could improve and expand it into something much bigger. So, we are considering greatly expanding that update into something far bigger than a major update, and perhaps a whole new DLC, but no decision has been made yet. It will all make more sense when we are further along and can share more info and made more decisions!

As always, we look forward to your thoughts and feedback. See you here next week for the minor update!

Much love <3,

Dear Stormworkers,

The new underwater major update is out now!

This update includes:

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.

We are really excited to release this new update and can't wait to hear back from players on your thoughts and feedback! Thanks to all the support and feedback we have received that has made this new update possible.

Much love <3,

The Stormworks Developers

v1.5.0 Underwater Update

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.

Feature - Added additional hospital-boat AI ships that now patrol specific biomes
Feature - New icon for addons with editable settings (in the addon selector menu)
Feature - #6898 Spawn Kraken button added to custom menu
Feature - Addon editor ocean toggle
Feature - 'Show timers' and 'Show rewards' mission addon settings
Fix - #1200 Vehicle save/load not serializing basic block damage & not generating damaged mesh on load
Fix - Ropes now use a constant number of physics nodes
Fix - Fixed 3 map icons sharing names internally causing them to render as a different icon
Fix - #5663 #6568 Missions/Cargo now check if spawn area is clear before spawning
Fix - Mission zones with no size now default to large instead of never spawning
Fix - Zone filtering causing certain mission locations to never spawn
Fix - #3132 Relative to seafloor mission tag behavior restored
Fix - Breakers/relays/chargers are no longer explode on damage
Fix - #7993 SRB fins now work underwater
Fix - Corrected buoyancy surfaces for large and medium warheads
Rework - The Kraken now only naturally spawns within the underwater biome.
Rework - Updated how mission descriptions are generated
Balance - #5026 Rebalanced mission rewards to be more generous
Balance - #5026 Rebalanced ocean lootboxes to be rarer
Balance - Increased cost of diving outfit to 2000

Addon Lua Api:

Added isLocationClear(transform, size_x, size_y, size_z)
Added getOceanFloor(transform)
Added "static" to getVehicleData()
Added to "parent_vehicle_id" and "parent_relative_transform" getZones()
Updated getCharacterData().interactible -> .interactable (Legacy spelling remains available)
Added radius param to addDamage and unlinked magnitude value from the radius.
Added a voxel pos optional override for setCharacterSeated instead of requiring to use the name
getVehicleData now includes a table named "components" which currently contains tables for seats, buttons and signs

Additional info is included in the in-game addon lua help tabs.

v1.4.20-24 (Hotfixes)

Fix - Issue with radar detection
Fix - Game audio issues / Mac audio crackling
Fix - Crash caused by door particles

Dear Stormworkers,

The next Stormworks major update is almost here! (Release date: 2nd June 2022) The new major update includes a new "ring of fire" biome with a series of fault-line volcanoes, underwater tunnels and trenches, new missions, and new sonar components! Here is some more info on what to expect:

New Sonar!

With the major update, we will add new sonar components. These new sonar parts are much more true to life, as they can listen in passive mode, as well as operate in active mode.

In passive mode, the new sonar parts detect noise producing components such as propellers, engines, etc. Sonar continuously listens in all directions at once, and this info is output to a composite channel in a similar way to radar.

In active mode, sonar emits a "ping" on command. This ping travels through water at 1480m/s and reflects off vehicles, returning their contact with a delay relative to their distance. Pings are considered noise producing, and are visible to passive radar.

New Missions!

The new missions include a variety of new types. Ocean floor rescue missions involve rescuing divers or submariners from below the surface, in a similar structure to the existing rescue missions. The depths of these missions is usually known and the player may need specialist rescue equipment. Occasionally these missions can occur where cave divers require rescue. These missions are probably the most dangerous as the underwater tunnel network is vast and it is easy to get lost.

Salvage missions involve recovering anchors, live munitions, or wrecked ships from the sea floor, and transporting them to their destination. These missions are more passive, with much longer timers as they are not emergencies and much less urgent. This allows more time to prepare, time to wait for the best weather, and perhaps even complete these missions in stages or in groups for maximum efficiency.

Repair missions introduce a new objective type where vehicles may need repairing with a repair torch. Some of these vehicles are on the surface, while others may be on the sea floor.

We are really excited to release this major update in just a few days on 2nd June 2022! Thank you to all the players who have given us feedback and support to make this update possible.

Much love <3,

The Stormworks Developers

Dear Stormworkers,

This weeks update is dedicated to bug fixes and improvements, as we prepare for the big major update in just 2 weeks!

There is a huge list of fixes and improvements, with the full change log below. Once major change is that we have completely replaced the audio code, to fix a range of audio issues, including those on Mac. The new audio code is based on our new audio library that we developed for use in Carrier Command 2. This was a lot of work but was an important change as it fixed some wide ranging issues.

In our ongoing mission to improve multiplayer, we have also greatly reduced freezing when a vehicle loads in. This freeze was caused by the vehicle data being sent in order to load the vehicle on clients. This is now done in the background, with only a small amount of compressed info being time-critical for the final stage of spawning the vehicle. This freezing was causing players to experience a few seconds of lag immediately after a vehicle loaded in which made vehicles unresponsive for a few seconds. This delay is greatly reduced and responsiveness greatly improved.

Thanks to everyone who has reported issues using the official issue tracker. The issue numbers are included in the change notes below for extra detail.

With just 2 weeks to go, we are adding the final touches to the upcoming underwater major update! We will release more info next week about a new component included in the major update, changes to the ocean, and the new missions! We are really excited for this update and can't wait to share more in this new release!

We recommend preparing with submarines, remote operated submersibles, and diving equipment!

Much love <3,

The Stormworks Developers

The new underwater biome includes over 40 square kilometres of underwater landscape, a volcanic ring of fire with several active volcanoes, underwater trenches, ruins, wrecks, and a vast network of underwater tunnels!

The new biome has many new named locations, in honour of the great community members and vehicle creators in the Stormworks community. These players have been selected because of their dedicated and selfless help given to other community members, or because of their incredible workshop creations that have risen to popularity on the workshop by community choice. We look forward to honouring these players in this major update.

There are also new missions including ocean floor submarine emergencies, ship salvage, sea floor cable maintenance, and more! Many of these new missions are ideal for spawning in the underwater biome, but can also appear all over the world of Stormworks.

We are adding a new glowstick first person item which can be used in a similar way to flares except is much less bright, has a much longer lifetime, and greatly assists location and path marking underwater.

The much-requested Kraken button will also arrive with this major update, allowing players to summon the kraken from the custom menu.

We can't wait to share this new major update on the 2nd June at 4pm UTC! Join us then for the big launch. And until then, be sure to check back here next week for an exciting minor update!

Much love <3,

The Stormworks Developers

Dear Stormworkers,

In this weeks minor update, we bring new train bridges to make it easier to get taller ships past the trainlines!

The trainline has long been a difficult obstacle for large ship creators, and a solution to this issue has been a frequent request from players.

With these new bridges, there are frequent passing places for tall ships to be able to cross the boundaries. We are also including AI pathing data for these new tiles, so that AI ships can better navigate across the trainline.

This update is also a huge bug fix update, with at least 40 new fixes! As previously discussed, we have been putting more focus into bug fix updates recently, with huge progress on the backlog of issues, and few new issues being introduced.

Please see the changelog below for full details of these new fixes and improvements!

EDIT: Here is the developers Q&A video as promised!

Much love <3,

Addon Lua Changes:

Added { = {x = world_x, z = world_z} } = server.pathfind(matrix_start, matrix_end, required_tags, avoided_tags)
Passing "ocean_path" as a required tag will produce the same behavior as server.pathfindOcean.

Default Ai addons now navigate different paths based on their size.
Large ships can no longer path through the sawyer river or under standard train bridge tiles.

Waypoint offsets are now randomized within the game code and can be adjusted by providing a "precision=X" tag which will confine the randomness within X metres of the node. As an example we have included this tag on all bridge waypoints in the default_paths playlist.

Dear Stormworkers,

This week we invite you to submit your questions for an upcoming developer Questions & Answers video! In these videos, we answer questions submitted by players, chat about Stormworks, and just get into that bit more detail than we usually can. We really enjoy these videos and it is great to talk to players about their thoughts and ideas.

Submit your questions here within a few days of this announcement (Thank you for all the submitted questions!) and we will answer as many as we can in the upcoming video!

The results have been coming back from the new crash reporter, and we are pleased that last weeks update reduced crashes by 60%. We have more crash fixes in next weeks minor update and expect to continue making progress through any remaining crash issues.

The next minor update is due out next week and includes many new fixes, as well as a new content feature. We are just finishing testing this update and there is a lot of quality improvements included so it should be another big changelog, like last week.

We are also finishing off the next major update, and are almost ready to plan a release date! No promises, but the release date and other info may follow in the next announcement in 2 weeks.

We look forward seeing what questions you have, and are really excited about sharing the next few updates!

Much love <3,

Dear Stormworkers,

This week we release minor update 1.4.17, including new outfit items, as well as many bug fixes and improvements.

This update is dedicated as a tribute to all of the Youtube content creators who are part of the Stormworks community. These content creators have a genuine passion, they are highly skilled communicators, editors, story makers, and are just lovely people with a positive energy that we admire. Building a Youtube channel is very difficult. It takes huge commitment, energy and skill. Building a brand and a business up from nothing is a great achievement that few have achieved.

I am not sure if we have spoken about Youtubers before, but Stormworks owes a great amount of it's success to the many content creators who have covered, supported, and promoted the game over the years. Almost all games that release on Steam don't reach enough players and fail. A lot of people would say that Stormworks has been lucky, but it wasn't luck. It was Youtubers, and players who gave their time up to help others, the incredible player created workshop items, and all the players who share our love of design and engineering.

In appreciation, we have added new branded shirts and hoodies to the Stormworks wardrobe in honour of Camodo, Spycakes, Beautiful OB, MrNJersey, Raptor, Frantic, ND, GQ, LynxHighland and RubberDuck. This isn't every great Youtuber, but we have added outfits for the top 10 youtubers by most viewed videos from the last year or so. Please consider checking out their channels.

And there is more in this update! Check out the extra wardrobe items and huge list of bug fixes and improvements in the patch notes below.

The new crash reporter that we added last week is working well and this update also includes some crash fixes so crashes should be dramatically reduced. We continue to monitor quality and will continue to add more fixes.

We have also added a new "auto" physics setting for the physics quality. The game will automatically step the setting up and down based on the physics simulation speed. If you do experience physics issues, you can always set this setting back to "high".

We hear the players who may be pointing out what their ideal next minor update is, and perhaps not all players watch as much Youtube as we do! But please do take a moment to consider how all players benefit from the content creators, vehicle builders, teaching players, and the community that has supported the constant free updates for the last 4 years.

We hope you found this weeks update interesting, and enjoy the new content and fixes! We look forward to your feedback :-)

Much love <3,

The Stormworks Developers

Dear Stormworkers,

This week development has pressed forward, with big progress being made on the 2 next minor updates, the next major update, and the new crash reporting system.

The next 2 minor updates have long lists of bug fixes and we are making good progress on fixes and improvements. We use the issue tracker to get info from players on where the quality issues are, and this gives us clear metrics on how many identified issues there are. This data shows we are steadily reducing the total number of bugs, and our new quality control processes are introducing relatively few new issues.

Next weeks minor update will also include a new cosmetic feature, and we will announce more next week as we release it!

Recently we have seen a surge in reports of crash to desktop, which is of major concern to us, particularly with our recent push to resolve issues and implement bug fixes. We have been unable to reproduce this new crash, with the game playing very stable in the office. Steam crash reporting only works with 32bit software, and most players play the 64bit version of Stormworks. We had tried using Bugsplat (a 3rd party crash reporter) but that also didn't work well for us. So, we have implemented our own and put it live yesterday. The new crash reporter is very similar to the built in Steam one, except it also capture data when 64bit applications crash.

Immediately we can see that the crashes are probably just a single issue related to physics objects being despawned, and we are already investigating how to fix. Moving forward, the new crash reporting system will help us monitor the stability of Stormworks, and quickly recognise any quality issues, as well as clearly see exactly which update introduced new crash issues.

We will return next week with the next minor update!

Much love <3,

The Stormworks Developers


Feature - implemented new crash reporting system

Dear Stormworkers,

Today we release the multiplayer bandwidth and vehicle desync update!

Bandwith and Sync Improvements

Players have told us the multiplayer experience needs to be improved, and we have been hard at work for a long time. We have made 3 major changes - we have reduced the overhead of our network protocol, vehicles now use a new technique to replicate, and we have created a proprietary compression algorithm that works specifically for Stormworks vehicle data.

This means that bandwidth usage has reduced by 60% to 80%, and the issue where vehicles would sometimes appear delayed is resolved.

This isn't the first multiplayer update we have released, and multiplayer has been a long-standing challenge for us. In Stormworks, vehicles can often have hundreds of individually moving physics bodies, as well as hundreds of complex logical components, all of which have lots of data that needs to be replicated between server and client. Stormworks is probably the most complex vehicle builder game, with the smallest block size, and the most data to sync up. This is simply a problem that other games have not had to solve and so requires a lot of engineering.

This new update solves a lot of these issues, and the new bandwidth reduction and netcode dramatically improves the multiplayer experience for a lot of players.

What About Slow Down / Slow Motion?

Some players experience slow-motion. This is caused by playing on a server with too much stuff spawned in, or the computer being below min-spec. When too many physics objects are spawned in and interacting with each other, the game will slow down. This is true for all physics sandbox games.

If you check the comments, I am sure you will find a few multi-threading and optimization arm chair experts who think the game just needs to run faster. However, the reality is that the physics calculations are complex, we have already optimized a lot, and there are no shortcuts if you want the detailed physics, robotics, ocean physics, and other mechanic that Stormworks has. It is the nature and the core of Stormworks to be a detailed physics sim.

So, if we can't magically make the same game run faster, what are the solutions? We are putting a lot of thought into this and welcome players to let us know your thoughts and ideas!

This isn't the only change and we have been also working hard clearing out the bug backlog. Please see below for the full list of fixes and improvements.

We hope this new update improves your multiplayer experience and we look forward to seeing you in-game!

Much love <3,

The Stormworks Developers

Dear Stormworkers,

This week is announcement week, as we alternate between game updates and announcements every Friday!

This week, we will discuss the upcoming updates and general plans we are making at the moment.

We already have the next 2 minor updates underway, with many improvements already complete and being reviewed. At the moment, we are regularly testing multiplayer as we want to make improvements to this area of the game. We are making progress, but this is still being worked on. Players can expect some improvement although we are not sure how much will be in the next minor update. Players can know this is being worked on and some progress is being made.

Otherwise, we have a long list of bug fixes and minor improvements that have been requested on the issue tracker. We are working our way through these, and we are making good progress. The new quality processes we now use have dramatically improved the quality of releases, with much fewer new issues, and we are fixing things at a good rate. Our goal is to reduce the total issues and get through the back-log of issues that has built up as a priority.

That said, we are still dedicating some resource to feature updates and major updates! We have loads of minor updates planned for the rest of the year and we are working on the next major update which should release at some point this summer. Our support plan for Stormworks continues to run indefinitely, and we are already discussing update ideas for the rest of this year and into 2023.

While we are committed to supporting Stormworks into the future, we are also thinking about other projects. The engine powering Stormworks is our own in-house engine and is now 6 years old, so we are discussing how we want to do things differently in the future and looking at creating a new engine that could power our next generation of game. This is still in the game-engine design stage and a new game is still a long way off.

Be sure to come back next Friday or a new minor update release!

And do let us know if this style of announcement is useful! We want to keep players in touch with the studio's plans, but with our personal style, we prefer to "do" rather than "talk", and we prefer not to give too much detail on anything until it is complete and working, so that we don't disappoint.

Much love <3,

The Stormworks Developers
