An epic battle of a lone marine against the forces of hell,

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 Kickstarter Launched!

Jupiter Hell, the spiritual successor to Doom the Roguelike, has now launched on Kickstarter!

Jupiter Hell Kickstarter

With Jupiter Hell we are aiming to get a new generation hooked on the hardcore roguelike formula. Combining traditional gameplay with a modern look and feel, it is a game that can appeal to both long-term roguelike players and new gamers that have embraced the likes of X-COM.

We need your support to make this happen! Please visit the Kickstarter page, check out our video and the details of the game, and pledge if you can. You help in sharing news of this is also much needed - please spread the word and bring Jupiter Hell to everyone!


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.
