An epic battle of a lone marine against the forces of hell,
taking place on the moons of Jupiter.



October development update

Development of Jupiter Hell marches on! You can keep an eye on the latest via our regular tweets and Twitch streams.

We have had some delays though. The original plan stated an Early Access version by November. Development is going very steadily, but with some things taking longer than anticipated and some of the development schedule being rearranged. Our current plan is to shortly release our third pre-alpha to the Inner Circle, and then the alpha by the year end.

Further development updates:

  • Two new programmers have joined the team. Olgierd is working on rendering and resource management. Emil is working on the game’s audio engine.
  • We’re now integrating engine tools into the game which will make the Jupiter Hell more open to modding. This was originally planned to be done much later, but is far more effective if done at an early stage.
  • Physics in the game can been optimised, meaning it will perform much better on a wide variety of machines.
  • Shadows have been improved, and a new optional shadow algorithm will be available for stronger hardware (see comparison below).
  • Resource management has been added to the game.
  • We have a new sound engine ready for implementation, with Roland working on the soundtrack and audio samples.
  • New tilesets and enemies have been added.

You can find more info, including some cool concept art pieces, on this month's Kickstarter update.

Inner Circle pre-alpha launched

The Inner Circle pre-alpha has now launched! Inner Circle backers can reach it on the Jupiter Hell forums. It’s very basic at this stage, with several known bugs and incompatibilities. But if you have IC access then please check it out and give us your feedback! You’ll see a lot more development of this in the near future, with hopefully weekly builds. Find out more on our forum post (Inner Circle members only).

We also have a new programmer on the team. We’ve been getting him up to speed with the code and the engine, and he has already finished his first major project - porting the engine to Linux. We now have Linux support for the game integrated, and the pre-alpha is available for both Windows and Linux (64-bit only though!)

Kornel has been doing regular live development on Twitch, so be sure to check out his sessions if you want more of an insight into how development has been going. If you’re geekily into how all this stuff gets made then it’s a fantastic opportunity to see behind the scenes of the whole process.

Note that some Hotmail/Live users have been struggling with forum access. If that includes you then please get in touch with us! We’ll sort everything out :)

One Week Into Kickstarter!

It has been a busy week, with over 800 backers, 47% funding, Steam Greenlight campaign launched and lots of updates! Here are the highlights for those not staying up to date:

And we have more news and excitement to come :) If you’re not part of the campaign then join up now! If you’re a backer already then please help us spread the word to many more people. Hell is coming :)


Jupiter Hell is a 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, including (but not limited to!) shotguns, chainguns, railguns and the trusty chainsaw. All to the shine of CRT monitors and the tune of heavy metal!

Dive deep into a true form of the 30 year old roguelike game genre that has resurged in popularity. Experience turn-based, grid-based permadeath and fully procedural levels, all in glorious 3D visuals. Get ready for the spiritual successor to DoomRL, the parody roguelike that years ago streamlined the traditional format and popularised a new wave of accessible roguelikes. Distilled, hardcore gameplay, fast-paced challenge and limitless death all await.
