Early Access Game

Get instant access and start playing; get involved with this game as it develops.

What the developers have to say:

Why Early Access?

TL;DR: We intend to make the game the best it can be by listening to player feedback.

We believe that traditional roguelikes make best use of Early Access especially if they actively engage with their community. We promise frequent updates, usually twice a month, based a lot on player feedback - you can already notice this from our update history and some topics on the steam forums! Roguelikes have traditionally been a long-brewing expierience that like good wine got better with age.”

Approximately how long will this game be in Early Access?

“While we plan to support the game for several years with regular content updates, there is a state of the game that we can confidently call 1.0, which will provide a polished complete experience. We intend to achieve that milestone before the end of 2020.”

How is the full version planned to differ from the Early Access version?

“Roguelike development is usually a horizontal affair - adding more possibilities, more items, more traits and challenges, and adding more classes.”

What is the current state of the Early Access version?

“The game is playable from start to finish, all the features described on the store page are implemented. What we are still expanding upon is the breadth of the game - more item, enemy and level variety, more special levels and challenges and better modding support. We're also committed to constantly improving performance and visual quality.”

Will the game be priced differently during and after Early Access?

“We plan to gradually raise the price as we ship new content and features.”

How are you planning on involving the Community in your development process?

“Whether here on the Steam forums, or on our ChaosForge forums, be it Twitter or Reddit, we read all feedback. Anyone that has been active on our forums during our ASCII roguelike game days can tell that we treat all feedback seriously and very often implement player suggestions. Roguelike development is a very community driven effort :)”

Jupiter Hell 0.8.1!

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!

About This Game

Jupiter Hell is a classic, turn-based roguelike set in a 90's flavored sci-fi universe. Set on the moons of Jupiter, the game pits a lone space marine against overwhelming demonic forces. Rip and tear zombies, demons and unmentionable monstrosities, using classic weaponry such as shotguns, chainguns, railguns and the trusty chainsaw. All to the shine of CRT monitors and the tune of heavy metal!

Tactical, turn-based combat with real-time responsiveness

Benefit from classic roguelike turns with modern shooter sensibilities. Controls are immediate and accessible while retaining the back-end depth of a turn-based RPG.

Meaningful RPG progression

Customize your character with new weapons, items and abilities gained as you progress through a permadeath-prone hell. Beat the game to unlock more difficult challenges rather than grinding to make the game easier.

Randomized levels set all over Jupiter’s orbit

Blast through procedurally-generated civilian sectors, military space bases and mining colonies on the violent moons of Jupiter. Every playthrough you’ll find new ways to experience familiar settings.

Original shooter roguelike lineage

Jupiter Hell is built by ChaosForge, the team that’s been making top-down, cosmic hell roguelikes since 2002.
