We’ve got fantastic news to share today – our Closed Co-Op Beta is going strong, and we’re about to ramp things up! Thanks to your feedback, our network architecture and Survival Mode gameplay are shaping up nicely. We're now ready to speed up the invitation process and welcome even more of you into the action. In this post, we’ll walk you through what’s happening next and why we’re still keeping things closed – for now. Let’s dive in!
Everyone gets in!
Over 12,000 players signed up for the Closed Beta through Google Forms – and we can’t thank you enough for that. If you’re one of them and haven’t received your key yet – don’t worry. You’ll get your invite by the end of April.
Once that’s done, we’ll close the form and switch over to Steam Playtest sign-ups. That doesn’t mean the Beta is over – quite the opposite! You’ll be able to join the test through our Steam Store Page, and the first wave of Steam invitations will go out right after the first weekend of May. After that, we’ll keep rolling out keys regularly every couple of days.
Click 'Request Access' right below the demo option on out Steam Store page to sign up for Beta.
Why not just go Open Beta already?
We hear you – and we get the excitement! But there are a couple of good reasons we’re still keeping it invite-only for now:
The Closed Beta doesn’t yet reflect the final quality of online co-op. Bugs are expected, and sometimes new builds cause more issues than they solve. It’s all part of the process – and we want to make sure that only players who are OK with that kind of chaos are diving in.
By limiting access, we can respond to feedback faster. Every report matters, and we don’t want anything slipping through the cracks. A smaller test group lets us iterate in a more controlled way.
What’s next?
If all goes well, we’re planning to launch an Open Beta in early Summer. No promises – but that’s our current goal.
This next phase will focus on Campaign Mode Co-Op, and we’ll make it available through the experimental branch of The Riftbreaker on Steam. That will be our big stress test before calling the update ready for prime time.
Thanks for being here
We’ve come a long way – and it’s been quite the journey.
We started working on online co-op back in 2021, rewriting huge chunks of our engine to support a custom-built network architecture from the ground up. It was a massive challenge, but we knew it was worth it.
Our journey is well-documented in our "Co-Op when" articles – you can find them all here.
Thanks to your support, we ran our first tiny PVP connectivity test in August 2023. That laid the groundwork for the full-scale Survival Mode Co-Op Beta that began a year later – and we’re only gaining momentum from here.
Your feedback, patience, and enthusiasm have made this progress possible. We’re beyond grateful.
We’re just getting started – and we can’t wait to show you what’s next.

The Riftbreaker Closed Co-Op Beta Update, April 28th 2025
Hello Riftbreakers!
We have just published a new update for the Closed Beta build of The Riftbreaker. It features a new Survival Mission in the Acidic Plains biome, the prologue mission adapted from single-player, as well as a lot of fixes and improvements. Full changelog below.
The Riftbreaker Closed Co-Op Beta Update, April 28th, 2025 Changelog:
Changes
Added the Acidic Plains Survival Mission to the mission pool in the Closed Beta. We will be grateful for all error reports regarding this new biome.
You can now find Mech Upgrade modules with additional randomized and unique Item Drops. The stats are very far from finished, and there might be some OP combinations - let us know if you find anything that is out of order.
All melee weapon attacks and some projectile weapon attacks are now treated with lag compensation mechanisms, which should provide you with instant input response and a much smoother experience. Please let us know about all the issues you encounter with mech attack animations, inconsistent hitboxes, phantom hits, etc. This change has the potential to break a lot of things before it does its job properly.
Added the Prologue mission to the Beta build. Try to break it - we're pretty sure it works fine, but we'd like to get a confirmation on that!
Decreased the lightning strike Omega skill spawn frequency and damage.
Added a new Omega skill - Cryo Orb.
Changed the visual and sound effects for finding underground treasures.
Custom Difficulty settings have been temporarily removed from the Beta build
Reduced the Easy and Normal Tropical Zone survival mission difficulty - Omega creatures will arrive later than before.
Fixes
Fixed GUI button hitboxes for both gamepad and keyboard and mouse navigation on many screens.
Fixed some issues with the Load Save option in the Lobby.
Fixed gamepad navigation issues in many places, but it's not final yet.
Fixed chat layout and color coding.
You should now only see the base stats for mech upgrades during crafting.
Fixed some issues with the Decompressor production display and equip menu.
Fixed mismatched icons for Root Gun Extreme and Superior.
Fixed an animation glitch that caused weapons to behave strangely.

Research Tree Revisited
Hello Riftbreakers!
Last week, we gave you a glimpse into the structure of the new Expanded Story Campaign endgame. It was the first time we showed off our megastructures. Constructing these massive buildings will be the main point of your new mission on Galatea 37. Adding such an enormous extension to the structure of the Story Campaign requires us to reflect on various areas of the game and introduce improvements wherever necessary. You could already read about the overhauls of the weapon and loot systems and the addition of the Randomized Mission Generator. Today, we will tell you about another area of the game that will receive a makeover to facilitate our endgame design - the research system.
Click the image to view it in higher resolution. Here you can see two new additions to the research screen - a bar with all your stored resources and a fourth research tab. The megastructure research items are located in that additional tab. You will only see that tab if you enter the endgame.
Let’s start with the most significant change to the research system in the history of The Riftbreaker. Starting with the 2.0 version, all research items in the Story Campaign will cost not only time but also resources. Adding a research item to the queue will require you to pay a one-time resource fee. We understand this will sound controversial, but hear us out. In a rework as extensive as the one we are attempting, we must ensure that all elements are in harmony. The addition of the new loot system, the abundance of biocaches, the ability to generate infinite numbers of missions, and the increased rewards you’ll get from the Omega creatures have drastically increased the pace at which you can fill your resource storages and progress through the Campaign. Adding resource costs to research items adds more meaning and incentive to stockpiling resources and building up your economy.
Hovering over an item will reveal its cost. The amount of required resources will gradually go up as you progress through the research tree.
The one-time payment for research items also allows us to solve an additional issue. Previously, a player could add all the research items to the queue without worrying about the order. It was simply a waiting game before they unlocked all the items from the current tier. The new system adds a degree of strategy and depth to setting up the research queue. You must prioritize the technologies you need over those that could be useful later. Resource costs will also necessitate maintaining the economy for the entire campaign duration, as you will always have a use for the advanced and rare resources previously used only for specific buildings and weapons. It is also worth pointing out that these changes will only affect the Story Campaign. The rules stay the same in Survival Mode.
If you can't afford a research item you will be notified about it in the tooltip, as well as a small icon representing the missing resource next to the research item node on the research tree itself.
To make research management easier, we have also added one quality-of-life feature you requested. The research screen now features a search option. Simply click the magnifying glass icon in the bottom-right corner and type in what you’re looking for. The search option will highlight the research items corresponding to what you typed. It works for the name of the research item and the individual buildings or weapons that research grants you. For example, you can type in ‘Liquid Resources Handling’ and ‘Pipe’ - both will show you where to look for that technology.
The search bar will highlight all tech items that are relevant to your search. The search sticks when switching between pages, so you can check out all the branches without having to type again.
This is a significant change, which might seem radical. However, after playtesting the campaign several times, we concluded that it makes gathering resources much more rewarding. We encourage you to approach this change with an open mind. Not too long from now, we will start an Open Beta of the Campaign Mode on the Riftbreaker’s usual experimental branch, which will allow you to test these changes ahead of time and provide us with valuable feedback. If you want to know about this first, sign up for our newsletter, join our Discord at https://www.discord.gg/exorstudios, and watch our streams at https://www.twitch.tv/exorstudios every Tuesday and Thursday at 3 PM CEST. That way, you won’t miss any exciting news coming your way - and we have some great news coming at the beginning of the next week!

Beta Info & Endgame Overview
Hello Riftbreakers!
We have some exciting news for you right off the bat. We are speeding up the delivery of your beta keys. We want to give access to everyone who signed up for the beta via our Google Form by the end of this month. Additionally, you can now sign up for the Closed Beta of the Co-Op mode via the Steam Playtest access request right on the store page of The Riftbreaker. This is an additional option for those who can’t or don’t want to sign up via Google Forms. If you sign up this way, you will be granted access to the beta next month.
Most of the time, when we talk about the features of the upcoming Riftbreaker updates, we talk about the Co-Op Multiplayer mode. Working on this part of the project has made up a large portion of the last three years for us. Still, Co-Op is only one part of The Riftbreaker 2.0. Another considerable part of this free release will be the new endgame portion of the Story Campaign. It will expand and enhance the game's single and multiplayer experience, and we can’t wait to see you play it! This is a huge topic, and we can’t cover it all with just one news piece. Today’s article will give a general overview of the main objectives and the new activities we have prepared for you. Then, we will expand on the extra buildings, tech, and activities in additional articles. Let’s dive in!
!!! STORY SPOILER ALERT !!!
Please bear in mind that this article will contain technical and lore spoilers for the ending of The Riftbreaker’s main Story Campaign and the new endgame expansion. If you want to discover these parts of the game yourself, we recommend skipping this article for now!
The ending of the main branch of the Campaign gives you a choice: you can either go back to Earth and call it quits or stay on the planet and prepare it for the inevitable arrival of humanity. If you decide to return home, your Galatean adventure is over. You go back to your friends, family, the Riftbreaker command, and await your next assignment. The new, expanded endgame campaign starts if you stay on Galatea. Ashley mentioned several times in passing that she had a much better alternative for this planet - one that doesn’t involve turning Galatea 37 into a shell of its former glory by stripping it clean of its ample natural resources. It will take some time for humans to re-establish a connection with Galatea, so you have some time to work with.
Setting up the Rift Station is going to feel like child's play compared to what you are going to build in the endgame.
During previous Riftbreaking operations, humans always followed the path of least resistance. Instead of trying to understand, preserve, and protect their new colony world, their only goal was to build more factories, power plants, and dwellings. There was no ill intent behind these actions. Humanity has its needs - this is simply the quickest way to fulfill them. It comes at a cost - every new planet quickly becomes a carbon copy of Earth - a giant, sprawling city, with little trace of its natural ecosystem. Ashley hopes that she can prevent it when it comes to Galatea 37.
This GIF kinda gives you an idea of the sheer scale of these structures.
The technology to protect the planet's ecosystem is out there - humans just don’t bother building it because it’s expensive and complicated. Ashle’s plan is simple - do all the heavy lifting and build the infrastructure herself before other humans arrive. This involves building five megastructures. The megastructures are truly monumental facilities, much bigger than even the Rift Station itself. Each of the five structures you build serves a different purpose, but combined together, they will allow you to minimize your impact on Galatea 37 while still reaping the benefits of a brand-new colony world and its ample natural resources.
Here are your mission objectives - the five megastructures:
Quantum Cortex Laboratory - It is the brain of the entire operation. This building houses a quantum supercomputer that will store and analyze all the data for you. Having an operational Quantum Cortex Lab boosts your research speed by a significant margin and allows you to research other megastructures from the brand-new fourth research tab.
This is the fully built-up Quantum Cortex Laboratory with the setup required to run it. Start saving up your supercharged plasma today!
Nanobot Swarm Production and Control Center - Ashley will need lots of helping hands during her mission to protect Galatea’s ecosystem. Nanobots are perfect for that purpose, and this building will serve as their base of operations.
The view from the model editor, with close-ups of some details.
Gravitational Hyper Lens - This structure will serve as a giant stabilizer for the gravitational and magnetic fields of the planet, ensuring your systems stay operational for a long time.
As you can see, the megastructures are not only unique when it comes to the size - they also come in various shapes. Each of them will require you to find a suitable spot.
Hydroponic Sustainability Lab - This Laboratory will store, replicate, and nurture all the samples and saplings collected from among the Galatean wildlife.
Is this the fanciest greenhouse you've ever seen or what?
Mystery Building - We are not quite ready to tell you what this structure is. We can't show it, either. (Totally not because the model is not finished yet). It might be a giant computer, or an antenna, or a factory of some kind. Who knows? Put your best guesses in the comments!
The stages of building up the Nanobot Center. Building megastructures piece by piece will allow you to see the progress you make in real time, and pay the cost in just five easy installments!
Construction of your megastructures will take place in stages. Each stage will add new elements to the building, allowing you to see the progress you make. Building the megastructures piece by piece also makes their cost more palatable. However, you have to know that this will be a huge investment. The megastructures have a high upfront building cost and upkeep requirements. Your existing infrastructure most likely won’t be sufficient. This allows you to put the brand-new Orbital Scanner features to good use and establish new resource mining outposts.
Our artists have done an incredible job with the details on these buildings. They are our crown jewels!
If looking at the sheer size of these structures makes you shudder at the thought of reorganizing your existing bases, fear not. You don’t have to construct the megastructures in your Headquarters. Even better - they don’t need to be on the same map! You are free to organize them the way you like! Constructing all five of these buildings is a massive endeavor, and we don’t want to limit you in any way. If you want to set up five dedicated outposts for each megastructure - that is fine. You can also try to build all five on the same map for a bit of an extra challenge. It’s a crazy idea, but we like crazy.
Naturally, we couldn't resist playing around with some nice lights and reflections (although the effects and lights are not final yet!). Enjoy!
Designing a long-term mission like the one we’ve presented to you today involves a lot of variables. This is why we’re not sharing details like resource and upkeep costs yet. However, we can state that constructing the Rift Station is going to feel like a tutorial in comparison to the megastructures. Currently, we are playtesting the endgame internally - both solo and in the co-op mode. Each playtest we make is a new iteration with tweaked costs and requirements. Once we have something worthy of public scrutiny, we will let you play all this as an experimental update. As we prepare for the experimental release, you can expect more news about the endgame expansion in the coming weeks.
You can build these structures anywhere you like. There are no biome restrictions, and they do not need to be located within the same map.
We hope that this little sneak peek at the design of the free endgame expansion for The Riftbreaker got you excited for the upcoming updates. If you want to stay on top of all the news we publish, sign up for our newsletter, join our Discord at https://www.discord.gg/exorstudios, and join our streams at https://www.twitch.tv/exorstudios - we are live every Tuesday and Thursday at 3 PM CEST.

The Riftbreaker Closed Co-Op Beta Update, April 4th, 2025
Hello Riftbreakers!
We have just released an update for The Riftbreaker Closed Co-Op Beta. This update includes a new Survival Mode mission in the Crystal Caverns biome, as well as some other fixes and tweaks. The full changelog is available below:
The Riftbreaker Closed Co-Op Beta Update, April 4th 2025 Changelog:
Changes:
New Survival Mode map: Crystal Caverns. Venture into the maze of limestone caverns beneath the Galatean Tropical Zone. Dig your way through rocks and fight for survival in the darkness of this inhospitable place.
We have introduced some functional updates to the lobby screen. You can now open your server lobby before the start of the game. A lot of small issues with the new screen have also been fixed. Thank you for all the feedback!
We've added the 'Rich Presence" status tags for The Riftbreaker Multiplayer Playtest. Your Steam friends will now see a status that tells them what you're playing in the friends list.
Players can no longer block each other's projectiles with their own mech. This should make fighting hordes of aliens in a tight group much easier.
We have changed the nickname and healthbar display for players on the screen to be more legible.
Added per-player statistics filtering. With stats separated between the players, you will be able to see who's doing all the heavy lifting and who's just coming along for the ride!
Unique loot drops will only appear after the Armory is built to prevent issues with players getting hold of too powerful weapons too quickly.
Fixes:
Fixed an issue that could cause objectives information display to be doubled on the screen.
Fixed the size of some minimap icons to improve legibility.
Fixed some issues with animation times.
Included the raytracing stability fix, lowering the risk of crashes by a significant margin.
Fixed an issue that could cause buttons to get stuck, for example walking in one direction despite releasing the button.
Included several dozen small fixes for GUI.
Introduced many optimizations for performance, prediction algorithms, and the networking code.
Known issues:
Crawlogs might not get up after killing them for the first time.
Crawlog corpses behave in strange ways sometimes.
The destructible limestone rocks do not always display correctly, but they are fully functional.
If all Communication Hubs are upgrading at the same time, research will stop until the upgrades are complete.

Co-Op Status Update, April 2025
Hello Riftbreakers!
We send hundreds of invitations to our Co-Op Multiplayer Playtest for The Riftbreaker every week. Our playtester numbers are growing steadily, and we’re delighted to see many of you sharing your thoughts about the game with us. There is no doubt that we are close to the finish line. Everyone who signed up for the closed beta will get access before we switch to open beta. Before that happens, however, it’s good to look at the past couple of months of development and talk about the significant changes and updates we introduced. We’ll also discuss what’s currently in development and what improvements you can expect in upcoming builds.
Thanks to the weapons and loot rework, old toys became new favorites - laser is a mainstay in some biomes now!
A couple of months ago, we implemented a complete overhaul of the weapon and loot systems. Not all the changes we made hit the mark in the beginning, but we made huge improvements thanks to your extensive feedback after playtesting the game. After the rework, many previously obscure weapons have become not only viable - they got a new lease on life by becoming an excellent choice for certain enemies and biomes. This led to much more varied and experimental gameplay, which we love to see. Getting better tech from loot drops also gave players a much-needed boost in the face of relentless alien hordes with Omega creatures at the helm. We are pretty happy with the results, but this is by no means the system's final iteration- we will continue tweaking all possible values to make sure the game is challenging, fun, and rewarding.
Being able to disassemble weapons, mods, and upgrades all in one go was one of the most requested features. This will save you a lot of time, clicking, and micromanagement.
Tinkering with entire game systems is not the only thing we have been working on. If you have dropped by our streams lately (Tuesdays and Thursdays, 3 PM CEST at https://www.twitch.tv/exorstudios), you might have caught a glimpse of our newest Quality of Life feature - the mass disassembly system. It is accessed through the inventory screen and allows you to select several items you want to get rid of all in one go. You can choose the items for salvaging manually or use one of the buttons that will automatically select all the items of the corresponding quality level. After picking the items to be dismantled, click and hold the ‘disassemble’ button to confirm your choice. This system lets you dismantle weapons, mods, and mech upgrade modules, making inventory management simple and convenient.
This is probably not the final version of the lobby screen, but we're getting there.
A significant increase in player numbers also came with requests for quality of life upgrades in other game areas, such as the lobby screen and lobby invite system. This was long coming, as our placeholder lobby screen was constructed using the GUI elements we already had available. It was always meant to be made from the ground up, and the influx of new playtesters increased the priority of this task. We created an entirely new screen, where you can set up the initial options for the multiplayer session, load a saved game from before, invite your buddies from the Steam friends list to join, and chat before the game starts. We are still working on some functionality upgrades.
Thanks to lag compensation gameplay feels smoother than ever!
We have also made significant improvements in the game's network code by implementing lag compensation in the form of prediction algorithms. We simulate as much gameplay as possible on the client PC, and verify the state of the game world with the server a couple of times a second. This way, you get immediate feedback on your actions, without the feeling of delay between your input and a gameplay effect. Almost all dynamic gameplay elements are included in the prediction algorithms - creature behavior, projectiles, player navigation, and much more. As a result of all this work, the game is comfortably playable even at high ping values, such as 200 milliseconds. That doesn’t mean we can rest easy - we will continue working on the connection's stability and the reduced data transfer. Optimizing data transfer and improving the game’s responsiveness is by far the most time-consuming thing that we are working on.
Emotes require testing, too! Here are our high-quality, very mature and fancy animations.
Apart from playtesting the Survival Mode in the Closed Beta build, we have conducted several Campaign Mode playthroughs internally. Some of those tests were regular gameplay sessions, exploring all possibilities available to our players. However, we have also conducted thorough destructive testing, trying to break the game in every imaginable way. We tried to connect to the game randomly, drop out of it in the middle of important sequences, reconnect during loading, and exploit all the possible avenues that could break the game. We found a lot of bugs that way and managed to fix the vast majority already. We still have hundreds of bugs in our backlog, but we’re getting through them one issue at a time. Re-working the entire campaign mode for multiplayer is a huge undertaking, and we know we can’t find all of the bugs by ourselves. As soon as we’ve fixed all of the critical issues that we know of, we’ll move to an open beta on the experimental branch.
Our dream is to see players working together on their bases, sharing responsibilities as they go.
As a side effect of our Campaign Mode testing, we have ensured that all biomes are playable, at least when it comes to the base biome mechanics. Thanks to this, we will be able to release new maps for the Survival Mode in the Closed Beta. In the upcoming weeks, we plan to release a series of updates that will add the missing Survival missions to the mission pool, introduce new biomes, and bring in new enemies and challenges. This will significantly increase the replayability of the Closed Beta for our playtesters and allow us to find and identify all the issues that might have eluded us during our own testing. You can expect us to send out more keys alongside these content updates!
Not to spoil anything, but we are really close to some huge news. If you don’t want to miss anything, join our newsletter to receive notifications about the latest news for The Riftbreaker and everything EXOR Studios. You can find the link below:

Mod Spotlight: Expanded Arsenal 3
Hello Riftbreakers!
The player community is the backbone of The Riftbreaker - and always has been. Since the early days, you provided valuable feedback about the early builds, highlighting our successes and shortcomings. This allows us to improve the game and address the hiccups you encounter. However, giving us valuable insight is not the only thing you have provided us over the years. Another aspect you have excelled at is modding the game. You’ve been making them since the days of Alpha and haven’t stopped since. Every once in a while, we try to showcase the most interesting mods available. Some are featured more than once - and this is one such case. Let’s take a look at the latest update for WirawanMYT’s Expanded Arsenal!
You can expect a lot of explosions and destruction with this mod.
This update has taken quite a while to cook. WirawanMYT told us that besides having to sort out his IRL matters, he wanted to solve several issues in his mod backlog. He has been steadily fixing the Lua bugs in the mod since the earlier versions, but that has taken a toll on the overall pace of development. The release of World Expansion 3 has not made things any easier, introducing changes to existing Lua scripts and adding completely new ones, which Wirawan couldn’t have accounted for. Still, he braved on, learning and improving as he went. Here are some of the things Wirawan has changed in the latest update.
The reworked gravity blasters are great against hordes of smaller enemies.
Since the mod’s name is Expanded Arsenal, it’s natural that we will talk about weapons first. Wirawan’s mod introduced unique elemental heavy blasters with several firing modes - a regular one, a charged shot, and an alternative charged shot that triggered if you held the charge button longer. The latest update revises some of the second firing modes of these blasters to make them more useful—for example, the heavy magma blaster used to lay mines as an alternative charged shot. To improve its usability, it releases a magma wave instead, providing a temporary area denial against smaller mobs. Other heavy blasters changed similarly - we’ll let you discover precisely what they do.
The bouncing blade tower looks like a lot of fun, and a lot of carnage.
Magma artillery doesn't seem like it would do great in the MOIST conditions of the Fungal swamp, but it does!
This might look like white phosphorus, but it is not. It's cryo artillery!
The defensive tower suite has also received some updates. The volley tower has been replaced by an all-new type of tower that shoots bouncing blades. It is an excellent anti-swarm measure but not very effective against singular targets. The elemental artillery tower suite has also been reworked. Instead of being simple copies of the artillery tower with different damage types, various artillery towers now have different shells and impact effects. The acid artillery explodes into a gas grenade, affecting multiple enemies over a long period. The cryo artillery shoots a shell that splits into five smaller shells, dealing cryo damage in a wider area. The radioactive artillery uses a fragmentation shell and bursts into piercing radiation in a horizontal axis, dealing almost instantaneous damage. This expanded and reworked lineup of towers offers excellent strategic and tactical depth. Not to mention all the cool effects Wirawan made from scratch - you must see them for yourselves.
How about a flaming power rod, which turns into a tornado after it expires?
Wirawan’s mod had long-range missile towers long before the release of World Expansion III and the arrival of HCMs and Power Rods. The modded towers were more powerful, with their ranges spanning the entire playable area. With the addition of the “official” long-range towers (and the accompanying Lua improvements on our side), it made sense to restrict the range of the long-range towers. To make up for that sacrifice, Wirawan gives each missile tower a unique effect meant to deal with a specific type of threat. Now, you have plenty of towers to choose from, and they differ in the amount of damage and type, projectile travel time, or damage pattern. There are plenty of things to experiment with.
Each shot from towers like these will drain your liquid storage reserves, so make sure to have a lot stocked up in case of a lengthy defense.
Naturally, with great power comes great upkeep cost. To fully utilize the power of all the new defensive towers at your disposal, you must supply them with various fuel types, including several different liquids. Pipe crossings will become your best friends as you try to supply each tower type with its corresponding liquid and solve the pipe spaghetti. Moreover, Wirawan has brought back a mechanic from The Riftbreaker’s past. Towers have a certain upkeep cost when they are in idle mode. That cost rises dramatically when towers are firing at enemy creatures. This requires you to have a strategic reserve of liquids saved up for attacks, further increasing the strategic complexity of your base economy. Be sure to manage your resources wisely and plan ahead to ensure you always have enough reserves for when the enemy attacks.
Here, you can see enemies spawning from the magma eruptions. You have to stay vigilant, as the enemy might literally spawn behind your back!
Wirawan introduced innovations not only in the weapons department but also in the weapons department and wave spawn mechanics. By playing around with spawn rules, Wirawan managed to give some enemies the ability to spawn in unusual circumstances. For example, acid rain can bring in waves of creatures from the Acidic Plains biome as an “extra” attack outside the regularly scheduled ones. Earthquakes and other geological events might cause the Volcanic Zone enemies to appear. Falling meteors can take some bio-hybrids from the Metallic Valley along for the ride. You get the point - you are not safe and should invest in some new defenses and be on high alert. Hostile Galatean creatures may appear in unexpected places! And remember, Wirawan’s Omega creatures are much more potent than the ones you can expect from us!
Wirawan's Omega creatures can shoot down the incoming artillery projectiles.
It’s also worth mentioning that in the Expanded Arsenal mod, neither the players nor the creatures are defenseless against artillery attacks. Wirawan has spent considerable time implementing the “active defenses” mechanics, which allow all sides of the conflict to shoot down enemy projectiles mid-air. The player can do that using their defensive towers or mech upgrades - projectiles on the collision course will be automatically intercepted and shot down. Some aliens, especially the Omega strains, also possess this ability. However, such defenses aren’t impenetrable. Simply launch more shells and overpower the enemy’s defenses with the sheer volume of projectiles. You can also use weapons that do not use projectiles at all - like the flamethrower or laser.
Your towers gain the ability to shoot down artillery projectiles!
Unfortunately, so did other enemy creatures and structures.
The list of changes and improvements could continue, but trying the mod out on your own is best. Go to Steam Workshop or mod.io and download Expanded Arsenal. We recommend playing it in a new Campaign, though - there is so much new tech to learn that a Survival run simply will not do it justice. If you have any questions, the mod's author is very active both on Steam and on our Discord server at https://www.discord.gg/exorstudios, and we’re sure that he will answer all the questions you might have!

The Riftbreaker Stability Update, March 20th, 2025
Hello Riftbreakers!
We have just released a patch featuring our latest fix for the stability issues you have been encountering on Nvidia RTX GPUs.
A couple of weeks ago, we released a patch aiming to reduce the frequency of the crashes, but stated that it was not a permanent solution. We have conducted a thorough investigation and came up with a build that we believe will remedy this situation.
We found out that the problem lay with our acceleration structure. The raytracing implementation requires us to prepare Bottom Level Acceleration Structures (BLAS) and Top Level Acceleration Structure (TLAS). We have two types of BLAS - static and dynamic. The static BLAS contains information about static props and terrain. It is generated once, during loading, and stored for the entire gameplay duration. Dynamic BLAS contains information about all the other objects - buildings, destructible props, creatures, and the player. These structures need to be rebuilt every frame to maintain accuracy. TLAS uses the information stored in BLASes to provide us with accurate data during the raycasting pass.
If you want to know more about raytracing in our game, here's a detailed article about it: https://steamcommunity.com/games/780310/announcements/detail/2890711124511610519
We noticed that the issue occurred when a "fast rebuild" of our acceleration structures was triggered. It is an optimization technique that reuses some parts of the old acceleration structure to build a new one. When using fast rebuild on the new driver version, it was possible for the data stored in the GPU memory to get corrupted and result in a critical failure. This only became apparent on new driver versions. Disabling this optimization reduces the risk of failure by quite some margin, but we are not 100% certain whether it is the final fix. We will continue investigating this issue and hope that the patch we are releasing today will solve this problem for as amny people as possible.
We are very sorry it took so long for us to find and fix this error. It was well hidden - it relied on a specific combination of GPU, drivers, and other variables. Only one PC in our studio was capable of reproducing the crash on a regular basis, which made the process extremely tedious and difficult.
Please let us know if you encounter any GPU-related issues with the latest build. EXOR Studios
