Besiege news & patch notes

Hello everyone!

Today we’ve got our 6th and final development post for The Broken Beyond expansion, which releases in just 3 days time on the 22nd of June! This post is going to give you a sneak peak at some of the new space levels that’ll be dropping with the expansion.

The Broken Beyond campaign is set in the Aranea star system, home to the planet Besian which hosts Besiege’s original campaign. Besian is far from Aranea’s only inhabited planet and you’ll quickly find yourself coming up against a space-faring civilization known as The Void Drifters.

In an early level you’ll come across the crash site of a Void Drifter troop transport, perhaps destined for Besian as a scouting party or even an early invasion force.

As you progress deeper into the star system, you’ll encounter a colony, on the planet of Iotun, that’s been taken over by fiercely cute creatures known as Xenomaws. They’re very energetic so watch yourself!

The Void Drifters regularly host speeder races through the canyons of Doon. There are no rules, so demonstrate what a real machine is capable of and ensure you win no matter what.

The Drifters extract a variety of resources from all over the star system to supply their civilization. Their refineries and mines are easy targets for war machines hell-bent on chaotic destruction.

Along with the campaign, The Broken Beyond expansion also features its own sandbox environment which includes several planets and moons for you to travel between, manipulate and terrorise.

The new space expansion will also feature secondary objectives, just like the base game and water campaigns do, along with some new achievements for you to unlock. Sorry, not sorry 🙃

Launch Day Stream

Spiderling’s Community Manager Sam will be livestreaming the new expansion at 1pm BST on Monday the 22nd of June, so tune in to get an early peak and join the countdown to launch!

That’s everything for this week, we hope you’re as excited as we are about the upcoming launch! We can’t wait to see what wacky space machine chaos you unleash amongst the stars!

Cheers everyone, Von

Post 5 - Building for Space

Hello everyone!

With just over a week to go before launch, we’re going to take a look at building machines for space, examining some blocks in greater detail and exploring some important concepts you’ll want to consider when building your spacecraft!

Balancing Load & Fuel

So, first things first, getting off the ground with your rocket ship!

One of the most important balancing acts you’ll need to embrace when creating spacecraft in The Broken Beyond is ensuring you have enough thrust to get the mass of your machine into space.

• There are three elements to this equation you’ll need to balance; Weight, Thrust & Fuel.

• The greater your machine’s weight, the more thrust you’ll need to get it off the ground.

• The greater your machine’s thrust, the more fuel it’ll use.

• The more fuel stored on your ship, the greater its mass (weight). And so on…

With the new blocks added by the expansion, there are a lot of different configurations of boosters and fuel storage for you to experiment with to find what’s right for your machines.

Burning a low amount of fuel to generate a low amount of thrust over a long period is very inefficient. You’ll need to find a good middle ground where you’re generating a good amount of thrust, but not burning through your fuel reserves too quickly.

Those of you who are particularly discerning have already figured out that stacking small fuel barrels together provides more storage than a large fuel barrel while taking up the same space. However, a Large barrel storing 100 Fuel has a lower overall mass than 10 Small barrels storing 10 Fuel each.

However, a key difference between using a single Large Fuel Barrel and using several Small Fuel Barrels, is large ones have better wet to dry mass ratio. This means that a greater proportion of the blocks total mass comes from the fuel it contains and when a Large Fuel Barrel is emptied its mass will be lower than Small Barrels capable of holding an equivalent quantity of fuel.

Another important consideration is that the Large Fuel Barrel has significantly more attach points for linking it to other blocks. This makes it ideal to form the main structure of your machine, whereas Small Fuel Barrels stacked together provide far less points of attachment.

If you’re trying to be space efficient and maximise the quantity of fuel your machine can carry, small barrels are the way to go, but if you’re trying to be efficient with your mass to fuel ratio, large barrels are superior. There are tradeoffs with everything.

Another thing you might want to consider is separating your machine into two separate fuel networks if you’re using boosters and weapons that require fuel, like the Flamethrower or Blaster. If your fuel reserves run low, you might find your boosters draining the ammunition from your weapons to power themselves! 

Multistage systems are also a great way to make your spacecraft more mass-efficient, allowing you to jettison empty fuel storage or other systems that are no longer needed to complete your mission.

Steering in Zero Gravity

We briefly touched upon steering in space in our 3rd development post but it’s an area we’d like to expand upon a bit here as well.

For steering in space, there are 3 new main blocks you could use; the Control Thruster, The Inertial Steering block and the Booster block.

The Booster is designed to output large amounts of thrust and that coupled with the fact it consumes fuel, means it’s not ideal for reorienting your machine, unless speed is more important to you than control.

The Inertial Steering block is by far the most effective method for rotating your machine and it scales well with your machines size, making it impactful even with the largest of machine designs.

The Control thrust might offer a degree of finer control than the Inertial block, but the main reason we added it to the game was to allow players to create realistic replicas of real spacecraft. Control Thrusters can technically also be used as a method of low-impact propulsion for maneuvering your craft around in zero gravity.

Both the Control Thruster and Inertial Steering block also have an option for countering rotation, making it easier for you to stop your machine spinning. While this is very useful, it’s worth noting that the Control Thruster has the potential to knock you out of a stable orbit as it makes continual adjustments.

Atmospheres & Aerodynamics

As discussed in previous posts, The Broken Beyond features atmospheres which enable aerodynamic blocks to function.

Aerodynamic forces however are not consistent across all atmospheres as their density can vary, with lower density atmospheres providing less aerodynamic forces on your machine. There also isn’t a hard edge to atmospheres where aerodynamics suddenly cease to function, the forces will fade as you transition into space with an approximation of the barometric formula.

As a practical example, creating a plane for use in a low density atmosphere (like a gas cloud in space) will require its design to maximise lift and propulsion in order to function properly.

We also briefly mentioned in a previous development post that entering an atmosphere too quickly or at a bad angle can significantly heat your machine, causing it to burn up. This hazard can be countered by heat-shielding your machine using armour and some other metal blocks to protect vulnerable parts from burning. Placing these parts on the forward facing parts of your machine means they’ll take on the brunt of the heat during re-entry.

Misc Points

Another area of Besiege that works differently in space is fire. Although it is still possible to create flame outside of an atmosphere, in many instances it’s a lot less reliable and the risk of fire spreading between blocks is significantly reduced.

A classic method of propulsion in Besiege is heating a water cannon with a torch to produce steam, but in space torches are unreliable and don’t provide a constant flame. If you wish to use this propulsion method outside an atmosphere, you’ll need to use a Flamethrower which in turn requires fuel.

Something else to consider when designing your machines for space is that you’ll rarely need to fire in the same direction that your ship is pointing. So placing all your weapons facing forward isn’t always wise and you may wish to create turrets to ensure you can target enemies independently from your ships flight direction.

That’s everything for this post, next week will be the final development post before the expansion’s launch on the 22nd of June and we’ll be taking a look at some of the new levels which make up the space campaign!

We hope you’re as hyped as we are for the release and encourage you to wishlist The Broken Beyond if you haven’t already.

Cheers everyone, Von

We’re now less than two weeks away from our next major expansion! Working on The Broken Beyond has been a huge journey for the team and we can’t wait for everyone to finally get their hands on it. We’ve poured a lot into and all the support so far has meant the world to us.

If you haven’t already, please drop us a wishlist and help spread the word. It genuinely makes a huge difference and we’re so excited to share what we’ve been building.

Development Post #5 drops this Friday. Keep an eye out!

Cheers everyone,

Sam

If you'd like to be featured in our next Community Highlights, make sure to use our special hashtag #BuiltWithBesiege on Twitter or share them with us over on our Discord. Alternatively, you can reach out to Sam (Discord) who will be vetting submissions.

Hello everyone!

The Broken Beyond will be available to buy & play on June 22nd, in just over 2 weeks time!

Last week we began showing off 7 of the 13 new blocks that The Broken Beyond expansion contains and this week we’ll be continuing that theme by revealing the final 6, all of which are part of or use the new fuel system!

The Fuel System

Balancing fuel loads is a big part of launching rockets into space in real life, so we wanted to bring that resource management challenge to Besiege’s space expansion as well.

Fuel in Besiege is quite simply named “Fuel” and it can be stored in large containers and distributed to blocks which need it. Currently there are only three blocks which require fuel, the new Booster block, the existing Flamethrower block and the new Blaster weapon.

For storing fuel there are two options, the Small Fuel Barrel and the Large Fuel Barrel. The Small fuel barrel can store up to 10 Fuel and the Large Fuel Barrel can store 100 Fuel. The mass of Large Fuel Barrels is 10 times the mass of Small ones and the mass of fuel storage blocks decreases as fuel is expended.

Placing fuel barrels (or blocks which require fuel) adjacent to each other connects them automatically into a fuel network that has a shared fuel reservoir that can be drawn on by any block that requires fuel.

Blocks storing or requiring fuel can also be connected using Fuel Hoses, which by default, automatically allow fuel to flow between the connected blocks. However, there are also options available via the parameter tool which allow you to configure keys for starting and stopping the flow of fuel.

You may also wish to connect or disconnect different fuel networks together during gameplay, in which case you’ll want to use the Fuel Coupler block. It works as you might imagine, connecting fuel system blocks together on a key press and disconnecting them on a key press. Upon decoupling, the block creates a pushing force to separate it from the connected block. The amount of force created can be customised using the Parameter Tool.

Determining the percentage of remaining fuel within a network can be done using a Fuel Gauge block. This Fuel Gauge is an automation/logic block, meaning it can be configured to emulate a key when a desired fuel level is reached within a connected network. The block also has a glass gauge on its side which visually displays the current fuel level of a connected network.

The new Booster block has a small fuel reservoir that stores 1 fuel. By default, the block expends 1 fuel for every second it’s activated but increasing the block's thrust also increases the rate of fuel consumption. The block can also be configured to start with less or no fuel in its reservoir.

The existing Flamethrower block is also compatible with the new fuel system. The Flamethrower uses 1 fuel for each second it’s activated and it contains an internal fuel reservoir capable of storing 10 fuel. This means that the block will continue to function the same way in base game Besiege as it always has, but can have its fuel extended if you have access to The Broken Beyond’s new blocks.

You might also notice that the Flamethrower’s wooden barrel is a similar size to the Small Fuel Barrel and stores the same quantity of fuel.

The Blaster… god it feels good to say that name, BLASTER.

The Blaster is a new weapon block, coming with The Broken Beyond, that fires super heated bursts of fuel that cause damage on impact and have the potential to ignite the target.

The Blaster currently expends 1.25 fuel per shot, but this may need balancing again before or after launch.

This is an extremely powerful block which we’ve added to help you fight in the fast paced, high maneuverability environment that is space! 

That’s everything for this week but next week’s post will be all about building for space, where we’ll explain some fundamental design principles of building space machines and dive into some finer details of block design as well.

We hope you’re as excited as we are about the upcoming launch on June 22nd! Please consider wishlisting to get notified of the release, it really helps us out.

Cheers everyone,

Von

Post 3 - Space Blocks

Hello Everyone!

It’s time for another Broken Beyond development post and this week we’re looking at some of the new blocks coming with the expansion, all designed for space!

If you’re excited for The Broken Beyond, wishlist below!

Development Post

The Broken Beyond brings with it a massive 12 new blocks, all designed with building space machines in mind!

The new expansion also introduces a fuel system to Besiege for the first time and we’ll be diving into the details of that in next week’s post.

One of the key blocks introduced in this expansion is the “Booster”, which works both inside atmospheres and in the vacuum of space. The Booster is a powerful rocket engine capable of producing large amounts of thrust!

Despite its power, you may need several boosters attached to your machine to make it capable of leaving a planet’s atmosphere, depending on the size and weight of your design.

The booster requires fuel to operate and although containing a small internal reservoir itself, you will need to supply it with additional fuel to achieve any meaningful flight-time in the atmosphere.

We’re also adding a Powered Metal Wheel with The Broken Beyond expansion, designed for use in space-like environments where traction is important or possibly difficult to achieve.

Besiege’s existing wheels will work in the new space environments, but we felt the block selection was lacking one that provides continuous traction over rough terrain. It also wouldn’t have been right to release a space expansion without some kind of rover wheel!

While Booster blocks are great for propelling your machine through space, they’re quite large and don’t provide particularly fine levels of control, making them less useful for steering/orienting your machine.

Therefore, we have added two types of steering block specifically designed for orienting your machines in space, each functioning in different ways.

The Control Thruster works similarly to an “RCS Thruster” (used by real spacecraft), expelling gas in one or several directions at once to provide a reactive force.

It also has an option for countering rotation, effectively providing automatic counter thrust to the rotation you’ve initiated. This means you don’t have to worry about manually cancelling out your machine's rotation by firing the thrusters in the opposite direction.

This block is great for fine adjustment to your orientation and works best on smaller, slower moving machines.

For larger or faster moving machines you’ll probably want to use the Inertial Steering block to orient your machine through reactive torque, albeit to an unrealistic degree.

The block also has an option for countering rotation and options to change the rotation & counter-rotation speeds.

The Inertial Steering block is ideal for providing very quick orientation of even the largest machines and we anticipate seeing it used in many fighter type space-craft designs!

Controlling your machine inside an atmosphere is quite different from space, as aerodynamic forces come into play! Although Besiege already has a good selection of aerodynamic blocks for creating flying machines, we felt some additions were needed to plug a few gaps.

The Rocket Fin rotates to guide airflow around your machine, allowing you to alter its path through the atmosphere. They also provide a stabilizing effect even if you don’t rotate them, ensuring your machine flies straight and true.

The Grid Fin works in the same way as the design popularised by SpaceX several years ago. It can be opened or closed to add or remove aerodynamic drag from your machine, essential for slowing your descent!

Another block we’ve added to help you slow your machine’s descent into an atmosphere is the Parachute block. The parachute can be deployed with the press of a button and its size can be customized using the keymapper tool, allowing you to decrease or increase the amount of drag it produces.

That’s all we’ve got time for today, but next week we’ll continue our breakdown of The Broken Beyond's new blocks and take a look at the new fuel system!

If you’re hyped for the new expansion, don’t forget to join the discussion on our Discord and wishlist The Broken Beyond!

Hello Everyone!

Today we’re delighted to share the second in a series of posts which delve into the upcoming Broken Beyond expansion and its exciting new content!

If you haven’t already, please consider wishlisting the new expansion as it helps us reach more physics building enthusiasts and will keep you updated about its release.

Development Post

Last week we began explaining the fundamentals of space in Besiege, delving into gravitational mechanics and our Newtonian physics simulation. This week we’re going to take a look at The Broken Beyond’s atmospheres and how your machines will interact with them!

With the Broken Beyond expansion, we wanted to capture the stark difference between being in a planetary atmosphere and being in the vacuum of space, both with physics mechanics and beautiful visuals.

Working with talented “shader sorceress”, Freya Holmér, we’ve been able to create stunningly beautiful atmospheres for Besiege’s planets. We wanted them to feel like miniature worlds brimming with character and we’ve only been able to achieve that with her exceptional shader work. Thank you Freya!

Inside planetary atmospheres the physics of aerodynamics is applied to your machine, allowing you to move your machines through the air with propellers, create lift with wings and slow your machine down with drag. This means that for a truly inter-planetary machine, you’ll need a design that functions aerodynamically but can also propel and steer itself in the vacuum of space.

Reaching space requires a powerful machine, capable of escaping a planet’s gravitational pull, but landing in a planet’s atmosphere requires control. You will need to establish a course bringing you to your desired destination, accounting for or utilizing the gravitational influence of planets. It’s also essential that your machine can control its descent into the atmosphere, slowing its descent enough to avoid burning up or crashing into the ground!

This week we also wanted to show you a nifty little trajectory prediction tool that we’ve worked into the expansion. It’s designed to help you determine your machine’s path through space, whether you’re on a collision course, or see whether you’ve managed to establish a stable orbit.

To use the tool, you simply zoom out far enough from your machine and a prediction line will appear, showing where you’ve come from and the path your machine is likely to take (in the final version, your predicted path will be a dashed line).

Different colour lines tell you different things about your trajectory;

• A red line indicates that you’re on a collision course with a large object, such as a planet.

• An orange line shows that your path is predicted to enter an atmosphere.

• A yellow line tells you that your machine has reached escape velocity.

• If none of the above are true, the line will be green or turquoise. This likely means you’ve established a stable orbit around a planetary body.

That’s everything for this week, but next week we’ll start showing off the expansion’s new blocks, which constitute the most blocks added by any expansion or update ever!

Until then, please wishlist The Broken Beyond if you haven’t already and help us spread awareness!

Cheers everyone, Von

Hello everyone!

Today we’re pleased to share with you the first in a series of development posts covering various aspects of the upcoming Broken Beyond expansion for Besiege.

We’re also excited to say that we’re still on track to release the expansion in Q2 of this year! Wishlist now to get notified.

Development Post

For this first development post we’re going to start by talking about Space in Besiege, how it works and what you can expect from it.

The scope of playable environments in this new expansion are much greater than any previously in Besiege, helping them feel more like miniature worlds than isolated dioramas in a void. Our goal has been to achieve a good balance between the epic scale of space with fun and interesting miniature worlds that follow Besiege's traditional diorama style.

When it comes to physics our goal with Besiege has always been to create a middle-ground between realistic simulation and quirky physics, a philosophy we’ve taken into this new expansion as well.

The Broken Beyond offers you the closest experience to a true Newtonian simulation, pushing the laws of physics into the realms of mind-bending wackiness! 

Large space objects like asteroids, planets, etc, have their own gravitational fields which fall off according to the inverse square law, meaning the force applied to your machine decreases drastically as you move away from its source.

There are a variety of different gravitational fields in The Broken Beyond, which have enabled us to create everything from realistic planets you can land on, to planetary discs you can drive around or fall off to the planet below!

Planets have “Spherical” gravity fields that pull everything towards their center or core which enables you to establish elliptical orbits around them. For more unusually shaped objects like lumpy asteroids, we combine several gravitational fields together with some clever maths to make them feel realistic to drive upon. These fields present odd looking paths for orbiting objects, following the contours of the Asteroid.

Platforms use a cylindrical form of gravity, where objects are pulled toward the faces of a cylindrical shape. This keeps the gravitational forces consistent, rather than strongest at the center of the platform, and causes orbiting objects to follow the cylindrical shape.

Finally we have the “Circular” gravitational field, which pulls objects directly down onto it or up onto its underside, creating an almost two dimensional ring doughnut to drive around with a hole in its center.

The Broken Beyond simulates the gravitational fields of all large objects in levels, enabling you to jump between asteroids or establish complex orbital paths around several celestial objects at once.

Although the expanse between planets in Besiege is a vacuum, it’s far from empty. Space debris litters the star system - countless rocks to collide with your ship, meteoroids to push around or smash into one-another, and even moons that you can send crashing out of orbit!

I’m afraid that’s everything for this week, we hope you’re as excited as we are about The Broken Beyond’s upcoming release! Next week, we’ll continue our “Simulating Space” theme with information about planetary atmospheres and how they affect your machine. We’ll also be showing off a neat little tool to help you navigate across the star system, and maybe we’ll take a look at a miniature singularity…

If you haven’t done so already, please do wishlist The Broken Beyond! It’ll let you know when the expansion releases and it really helps us spread awareness of our new passion project! Until next time, cheers everyone, Von

Hello everyone!

Today we’ve got another quality of life update bringing a host of new features and changes for players both new and existing! But before we delve into the details we’d just like to say a big thank you for all the interest and support that’s been shown for Besiege’s upcoming space expansion: The Broken Beyond.

If you haven’t already, please wishlist the expansion as it really helps us out!

For this update, community modder dagriefaa has been working tirelessly on implementing some of the community’s most popular mod features and requests into the base game, so a huge thank you to him from all the team at Spiderling!

To start with, you can now remap hotkeys for multiple blocks at the same time, improving your ability to quickly customise your machine controls. The “Paint Bucket” has also received some attention, with changes that should make it much quicker and easier to apply & change the block skins you commonly use on your machines.

For less experienced players we’ve added a host of tutorials to The Splintered Sea expansion, that will teach you the fundamentals of building aquatic machines, from ships to submarines! We’ve also updated a bunch of the game’s block tooltips to make them more consistent and offer you more details of their stats.

Both the Cannon & Water Cannon now have a higher maximum power of 3x, instead of the original 2, and new graphics options for higher FPS and Vsync have been added. These features and many more are all detailed down in the changelog below, so do take a look and don’t forget to wishlist The Broken Beyond, coming Q2 2026!

Cheers everyone, Von

Today we’re excited to announce The Broken Beyond expansion for Besiege, coming to Steam Q2 of 2026! The expansion takes Besiege’s classic gameplay into space, with a new campaign, a suite of new space themed blocks and a new sandbox environment.

Taking Besiege into space has been an ambition of ours for a long time now and, with The Splintered Sea released, we felt space would make a great focus for our next expansion!

Those of you who’ve been around for a long time might remember a small moon object in orbit around the Besiege planet, on the title screen. Originally we intended this to be a simple low-gravity sandbox to play around in, but following the addition of the Zero-G god tool, it felt somewhat superfluous.

We decided that if we were to explore space in Besiege, we’d make something far grander that fully explores all the fun & creative gameplay it has to offer.

Wishlist The Broken Beyond Now!

The Broken Beyond provides a simulation of space that balances realism with the rule of cool, allowing you to take full advantage of gravitational mechanics to slingshot your machines or establish stable orbits.

Many celestial bodies in the expansion will also have their own atmospheres, affecting the forces applied to your machine and the way some blocks function.

Space will present the greatest challenge to your engineering & piloting skills so far, but fear not, there will be a suite of awesome new space-themed blocks to help you achieve your goals and conquer this new frontier.

In the run up to launch we’ll be publishing a number of development posts which delve into more detail about different aspects of the expansion and next week we’ll be releasing another free update to Besiege, so stay tuned for details.

We hope you’re as excited to hear this announcement as we are to make it. We can’t wait to see what you guys make of this new expansion to Besiege! Cheers everyone, Spiderling

Hey everyone, It's Awards season again!

While most categories celebrate the biggest new releases of the year, there’s one that feels like it was made for games like ours, the “Labor of Love” award.

This year marked Besiege’s 10th anniversary. Ten years of building absurd contraptions, watching them explode, and immediately creating them over and over again. We’ve launched major anniversary updates, built an entire VR version, released the game on mobile, and are hard at work on our next ambitious expansion. 

But Besiege isn’t just something we’ve built. It’s something we’ve built together. To the workshop creators, the Discord community, the YouTube engineers, and most importantly, you, the players, you’ve kept this community alive, inventive, and absolutely unhinged in the best possible way. Every update we release, every little detail we polish, is for you, because you’ve made Besiege more than just a physics game. You’ve made it a world.

So if you’ve ever laughed at a machine mishap, marveled at someone’s ridiculous creation, or just enjoyed destroying a castle in the most unnecessarily complex way imaginable. We’d be honored if you nominated Besiege for the “Labor of Love” award in this year’s Steam 2025 Awards. ❤️

Thank you for ten incredible years, and trust us, we’re nowhere near done.

Much love,

The Spiderling Team

Hey all!

Community Highlights is back with our eighth edition! It’s been a busy year between the anniversary updates and the launch of Besiege VR, and the community hasn’t slowed down one bit. This time around, we hosted a Level Contest, and the creativity you all brought to the table was incredible. Now it’s finally time to show off some of the best builds and announce the winners!

🥇 1st Place: Buckshot Roulette by Wogiao

🥈 2nd Place: Dune by ChrisGun

🥉 3rd Place: Gate to the Expanse by Brammer001

Honorable Mention - Dust ll by 5Puff

This contest proved to be our toughest yet, with multiple ties and an incredibly high standard across the board. After much deliberation, we ultimately made the difficult choice to select the entries we felt represented the very best. Massive shoutout and thanks to everyone who entered. Every level brought something fresh and inventive, and it wasn’t easy narrowing it down to just three winners. The creativity across all the submissions was incredible, and we couldn’t be prouder of the community’s work.

Now, time to get into this month's highlights!
