And here we go again with the obligatory post-update bugfix patch :P

Most important thing adressed is the reduction of VRAM usage that was creating some serious issues on low-end graphics card. This might solve some crashes and framerate loss after update (please comment if it helped you). Apart from that some minor gameplay glitches have been fixed.

Stay tuned for the next feature update, and thank you for playing Jupiter Hell :)

It's update time again!

This release has some significant gameplay changes that will shake the meta! The tl;dr: we removed Eagle Eye, added Aim action and new traits, revisited and improved "transition" levels (first and last levels of a moon), improved manual targeting, balanced a shitload of stuff and added plasma ravagers. A more detailed description follows!

We've rewrote the accuracy calculations and decided it's time for a significant changes in this territory. Following our design goal of not having traits just increase numbers, we've removed Eagle Eye. In turn we added a new basic action, Aim, activated by waiting (the same as hunker - you can have both now!). It gives a whopping +50% to accuracy (up to 100% after two waits). But there's more - several new traits have been added instead! Marine got Focused fire (+10% accuracy to every next successive shot if only shooting), Scout got Deadly precision (your Aim bonus is also a bonus to critical chance) and both Scout and Marine got Steady shot (retain the aim bonus after shot). Technician already benefits much from Aim synergy with Hunker, so we gave him a different trait - Tinkerer (+2 charges on stations).

Looking at aim we obviously looked at cover too, now accuracy always helps to avoid cover properly - this fixes a few wierd behaviours too! At the same time we noticed problems with shotgun damage vs cover. Movable cover was taken into account, but wall cover wasnt. We decided to go halfway - cover affects damage, but only half as it affects accuracy of weapons. To offset shotgun stopping power, we increased basic shotgun damage.

Following that we took a look at ranges and noticed that they're not to clear. The minimum range was tweaked so now it's the minimum range at which you have full accuracy, and the max range is the range at which you still have any base accuracy. We tweaked some values to a couple weapons, see CHANGELOG below for details - most notably chaingun has now minimum range 3.

Accuracy also made us take a look at manual targeting. Now the last manual target is remembered unless you move, and as a bonus you can see the health of inanimate objects! I hear rejoicing from blind fire abusers, but hold your horses - aiming at stuff you don't see no longer takes accuracy into account (how can you aim at what you cannot see?) and has the standard -50% to hit penalty against things that are not targeted.

Further on the balance train we also took a look at modding. We decided to reduce the mod capacity increase of Whizkid to +1, but to offset that we decided to allow everybody to mod exotic (magenta) weapons with one mod. The idea is that due to overmodded basic weapons there was no place for exotics or ADVs in the meta unless you were a Technician (who can still multi-mod them).

A small change that might not immediately pop from the list - enemies are now more aggressive, especially in their optimal range. They will more likely shoot instead of moving, especially at the higher difficulties.

We hope that some of the balance changes will introduce more weapon variety viability as well as make mid-late game harder (e.g. we buffed the armor of post-Callisto formers and Summoner). The latter goal is still in the works though (in the meantime play around with plasma ravagers). In general we hope that Scout got a general buff in this release to make him as viable as the other classes - between Deadly precision, Aim and the stealth vs melee improvement.

However, the most immediately visible change is the transition levels! No longer will people ask us how do you take an elevator from Callisto to Europa :P. We took the occasion to add some balancing too - e.g. you have all three energy weapons guarantee to appear on Io early levels.

Finally there are visual improvements with shadows and smoke effects. The former being a side effect of FINALLY fixing the Iris Pro shadow bug!

Full changelog below!


A traditional bugfix release will probably follow. Next update will probably be 0.9.0 (note that the scheme we use moves to 0.10.0 afterwards, so it's NOT 90% ). It will probably be out at the beginning of October!

Thank you, and good luck!

Hello marines, time for a content update! 0.8.2 is deployed and you can download it now (you might need to fully restart your client to trigger the update).

Please note there's no save compatibility - your previous run will be silently deleted. Your progress and statistics should stay unaffected.

Most notable change is the addition of the second Io branch - CRI Laboratories! It comes with its own special level - CRI Armory. We'll leave you to discover its secrets for yourself, although prepare as you would for Blacksite Vaults :P.

Second biggest change is Medical and Technical stations. They are carefully placed in terms of randomness (the bulk that you'll find is guaranteed), and allow for some control over your run. With Medical terminals you can either use them as stationary healing, extract a medkit out of them - a combination of both or even more :). Technical stations will allow you to better control your mod supply, or/and repair your armor.

Third topic of 0.8.2 is acid. You'll meet it both as a new barrel type, as well as in the furious hands of the archreavers. Due to the fact that this makes Anomaly even more deadly, we addressed the Friendly Neighbourhood Reaver issue, and guaranteed that those cozy creatures don't spawn right in your face.

Speaking of special levels, we've revisited some and improved the rewards for most of Callisto and Europa special levels. Among them you may find the newly added ADV rocket launchers and chainguns to even your chances out!

There are several smaller changes and bugfixes, most notably killing the fiend burn crash bug (hopefully for good!) and making Io and Boss Reavers not count to the 100% clear count (which should make some of you really happy).

Full changelog below!


It is quite possible that a bugfix release will follow, as our point tester is on vacation :P. Next update (0.8.3) should appear September 12th and should be more content heavy than this one!

Thank you, and good luck!

There was a serious crash bug with the CRI Armory that we needed to hotfix, so we took the liberty of fixing a couple minor ones too:

Hello marines! It's time for the first content/feature update! 0.8.1 is now deployed and you should be able to download it (you might need to fully restart your store client for the update to trigger).

Please note there's no save compatibility - your previous run will be silently deleted. Your progress and statistics should stay unaffected.

We've implemented a lot of changes and features, many of them suggested by the community - you might find one you suggested in this list :).

As far as new stuff goes, you'll mostly notice the damage types - EMP, Toxic, Fire, etc. Barrels now behave differently based on color, old enemies might have new attacks, and cyroreavers and toxic reavers will introduce you gently to the new damage effects. And to turn the tables you have access to new grenades - EMP and Gas (note that the old grenades have changed colors). There's a lot new exotic (magenta) weapons too!

Speaking of weapons the cell-weapon tier has been added - rifle, pistol and shotgun (bye bye armor :P). They all do plasma damage, which mostly behaves like pierce damage.

Early game benefits from slightly different gear between classes and a new Level 1 generator that eases into a given run by providing a more balanced first level clear. We also balanced armor and health drops a bit.

We're slowly working on improving Io too - you'll find the new Blacksite special level to be something a bit different from the old ones :).

AI has been more agressive. We'll be working more on the AI later, but you should definitely be able to kite demons now.

Angel of Shotgunnery has been moved to a higher rank requirement, and Angel of Carnage (which is subjectively more fun) has been unlocked in its place instead. AoSh should be easier now though, as we allow the use of grenades (and the plasma shotgun eats armored enemies).

Tough as Nails has been reworked to reduce the accuracy penalty instead of pain, and do it on a 50%/100% level.

UI wise, we've added a item description modifier (SHIFT or LTrigger on pads), which allows you to see the stats of a weapon on the ground (and compare them to the held weapon - nicer UI improvements comming to this later!), but also allows you to use the pickup key while held to use the item immedately from the ground.

Finally some visual improvements were done - to the particle and sprite effects and icons and to the visual rendering equations.

Full changelog below!



Apart from a potential bugfix release, the next update (0.8.2) probably will appear in two weeks, however it will be slightly lighter on content, as we'll be half or this period attending Gamescom. You can expect further gameplay improvements by that time though!

Thank you, and good luck!

We had two serious bugs that we needed to fix (fire fiend burn crash and Angel equipment issues) - and took that opportunity to do a small balance patch, changes below:

Hello marines! We're so glad that so many of you decided to join us at Early Access launch!

We'll start our Early Access updates with a bugfix release 0.8.0a to address most issues that we have found thanks to your reports. The release is live now, if your start screen doesn't state 0.8.0a, fully restart Steam to force the update!






The first content (0.8.1) update will come August 15th, so stay tuned!

Finally, after so many years, Jupiter Hell, our turn-based sci-fi roguelike, spiritual successor to "Doom, the Roguelike" is out on Steam Early Access!

Rip and tear zombies, demons, and heavy metal monstrosities with chainguns and chainsaws on randomized levels set all over Jupiter’s orbit. Buy, play and leave a review here! And most importantly, please help us spread the word! Share, send it to your friends, poke your favorite streamers, and share with your communities!

Thank you for being with us in this important hour! <3

It's the final countdown! This version changelog might be short, cause we don't want to destabilize the game before Early Access launch, however, two major changes have still made the cut.

First and foremost. There is a macOS version finally! It should be still considered experimental, as we didn't have the possibility to test it on a lot of devices (known significant issues happen on Intel Iris Pro 5200), and as yet not very well optimized, but it should be a reasonable start. Note that because we use MoltenVK and hence Metal, it will only work on macOS Mojave or newer operating systems. Also, we'll be rolling out a hotfix for bluish scanlines tomorrow.

Due to problems with app signing, for the time being macOS versions will be Steam only.

Second major change is an overhaul of lighting - not only we made stuff by default brighter (by changing default lights strength and HDR parameters), but we also brought light to levels that were poorly lit - most noticeable on BSP style levels with corridors.

Apart from that there are several bugfixes and a slight balance change to Io Gateway. Take note that the Reavers that spawn from that portal wont stop spawning until you enter it!

We are more or less in a feature freeze until Early Access release, not to mess stuff up. Some things that we still planned to squeeze in are almost ready, but will appear in the first update after EA, including a Black Site special level, a CRI branch for Io, energy weapons on Io and healing terminals. Stay tuned as Early Access is not the end, it's the beginning!

Full changelog follows:


Next versions will be Release Candidates for EA, only bugfixes, followed by feature-less 0.8.0. Once the game launches August 1st on Early Access, we'll return to regular programming.

P.S. Oh, and if you didn't see the Early Access launch trailer yet, enjoy ;):

This is a quick release, as we have some features that we still want to push before Early Access, and we'll need to feature-freeze the release soon! Apart from that some major fixes have been added too!

Most notably we added the last big change before Early Access - Player Progression - later in development there will be more content that it will unlock, but now you can give us feedback on the current locks - they should automatically unlock if you've been collecting badges, otherwise some work might need to be done to get back all the Challenges and Ultraviolence. New badges have been added so the progress goes smoother. The currently locked stuff should be achieveable by a casual player - if it isn't, please tell!

If for any reason you want to start with a clean state, delete player.dat from the game folder.

First part of the Io upgrades is also go - Io is 6 levels deep, is also inhabitated by former CRI soldiers, there's a new special level (Io Warehouse) and a new transition level at Io 6 - Gateway.

There's one balance change - SMGs should be a bit more accurate.

Notable bugfixes include speeding up the loading significantly, reenabling volumetric lights, and several crash fixes.

We need these last versions before Early Access tested as much as possible and as soon as possible, so please help us out on this last stretch! <3


Next version will be out really soon (if bugfixes are needed), or around Monday (last changes before EA). Good luck!

This may be a point release, but boooy a lot of new stuff is here! The biggest code-wise (but hopefully barely noticable) is the fact that we merged into a new rendering architecture with Vulkan as the default API. We only started optimizations on it, so the benefits as yet are small, but will ultimately lead to both performance gains as well as new graphical goodness. It is IMPERATIVE however to at least briefly test this release on your machine before Friday! Pretty please <3.

If you have any issues running the game (that you didn't before), please contact us ASAP! (preferably on Discord, but forums are also ok). If the game doesn't run at all you can also try passing --gl via right-click properties on Steam, but do report the problem anyway.


I promised new stuff, so another big change is the long awaited voice acting for our JupiterGuy, by the irreplacable Mark Meer! We still didn't add all the interactions that we wanted, but a lot of it is already in. Be warned that our hero has a foul mouth! To those offended by this or streaming/youtubeing (or playing with children beside them), there's an option to tone down the profanity. You can also raise it, but it'll just remove some of the non-profane options. If you're not a big fan of VO, or want to hear less of it because you're playing the hundreth damn time you can also configure the frequency - from off or plot-only quips, to the full package. Tell us what you think!


For the hardcore players, we invite you to try a bit of the old ULTRAVIOLENCE! While it isn't the highest difficulty we want to add, it should keep you entertained in the meantime. While on the topic of difficulty - we did some rebalancing - there are more enemies overall, Easy is easier (accuracy nerf to enemies), Medium is a bit harder and Hard should be even harder.


Next, we added a new weapon class - SMGs. These automatic weapons have poor accuracy (especially at longer distances), but dish a lot of bullets. The benefit however is that they benefit from pistol only skills.


Also noteworthy, each class now has a Skilled trait that improves their class active and passive abilities. Our scout is slowly turning into an assassin?


Rounding up the big ones, two Steam features were added - Steam Cloud Saves, and Steam achievements - the latter however work only partially - you wont be able to browse them on Steam until the game is officially released.

Apart from that a huge chunk of smaller changes and bugfixes awaits, see the full changelog below!


Next version (0.7.3) will be out in little more than a week! This will be the last version with new features before the August 1st Early Access launch! If all goes well we'll add account progression and finally upgrade Io to a worthy moon!

It's that time again! While we still are in the progress of updating Io, there's a regular drop of new features for the game for your enjoyment!

Most notably we finally added weapon and armor modding to the game! You can apply a single mod to any non-advanced weapon, and pick the new Whizkid trait to increse the mod capacity by 2 per level. Technicians are smarter, and can apply a single mod to advanced weapon or armor! Currently available mods are Power (damage or protection), Accuracy and Bulk (magazine size or armor durability).

We also upgraded the UI - this is not a full overhaul that is planned post Early Access release, but you'll find it a bit nicer to see things that are important. Speaking of which you can now turn off the CRT effects if you don't like them.

We're in progress of adding a new general purpose level generator (inspired by the awesome roguelike Cogmind) - currently, you can encounter it only on Io, but once we polish up the kinks it will be more widespread.

To add more tactical depth we added CRI phase devices (smarter than DRL's, because they try to teleport you to a safe place), and repair kits (replacing armor-shards - basically a carryable version).

Finally, there's a new challenge, probably the hardest and weirdest one yet - Angel of Vampirism.

Apart from that a huge chunk of smaller changes and bugfixes awaits, see the full changelog below!


Next version (0.7.2) will be out in two weeks time, and hopefully will come with Vulkan and OSX support, and a significant drop of tactical gameplay enhancements. Hopefully we'll finally hear the Marine swear too ;).
