About HELLION

✦ AI summary

Survive the harsh vacuum of space in this realistic multiplayer sandbox where orbital mechanics and complex physics simulation create a truly unique sci-fi experience. Build, explore, and cooperate with other players in an ambitious simulation that pushes the boundaries of what's possible in a space survival game.

Hello space survivors!

It's been a long time since the ideas of a future multiplayer space survival game were discussed among the founders of Zero Gravity and creators of Hellion. Our journey started with playing with orbs representing the planets, each carefully moved by skilled hands in a simulation of what would later become orbital mechanics in the game. From the very first moment, we wanted to make a complex and realistic simulation of a solar system within a multiplayer sandbox environment. The goal was huge and ambitious and the course set.

With a full team, it took us less than two years to make our vision into a reality. Hellion was launched in Early Access in February 2017. We succeeded in releasing a game that was almost impossible to be made, often having to cross and bend the boundaries of our game engine – Unity. The start was a little bumpy but soon enough players recognized that our game was providing a unique experience that could not be found in any other game. The support of our players has confirmed that Hellion is truly special and we are very proud of it.

We are also proud of you – our players. We couldn’t have even dreamed of creating such a dedicated and engaging community as ours is – both on Steam and on Discord. We are grateful for all the support you gave us during these years and for all wonderful adventures we went through while trying to survive Hellion’s gaze. This expedition left a mark on us for life. Together we built the world of Hellion.

Unfortunately, the cruel reality is – not enough players were brought into our world of Hellion to make it commercially viable. After the sloppy start of the game, predominately in terms of bugs and issues, we gave our best to fix the game and add new content via numerous patches and updates. Hellion grew, got better, but is still far from the original idea of what Hellion was meant to be. Factions, additional ships, trade posts, all of this was simply put aside since our team was constantly fighting technical issues, some of which were simply impossible to be solved for good.

That struggle is coming to an end. At this point, without an influx of new players, the game doesn’t pay for its development. That’s why we had to make some hard decisions…

Zero Gravity can’t afford for further development of Hellion. There will be no new updates, bugfixes or any official changes to the game.
However, since the game is playable and we believe it offers a unique gameplay experience, we want to keep it going for players who want to enjoy it.
Hellion will leave Early Access without achieving goals we originally set out to do.
In order to keep the servers up, we will continue selling the game on Steam. Since the game is not fully finished, the price will be lowered to 15 USD (starting tomorrow Oct. 16).
Control over the official servers will be handed to Hellion’s Discord moderators.
Moderators will stay in touch with us for any important events that might occur.

We are absolutely aware that many of you will find these news disappointing. This is a hard time for us. We invested a huge amount of effort and work into Hellion and our hearts and minds were in this project for many years. Now, Hellion’s development is coming to an end and we are sad that our vision for the game was not fully realized.

Once again, thank you for your support, ideas, reports, content you’ve created and everything else you’ve done for this survival expedition. Thank you immensely!

Yours,
Zero Gravity Team

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

HELLION is praised by players as a unique and engaging survival experience with innovative space mechanics that even exceed what competitors have achieved, though it suffers from bugs and an abandoned state that frustrates fans of its ambitious concept. The game is no longer officially available, but players recommend the Hellion Rescue Project community mod as a way to play it with improved stability and UI, suggesting those interested should seek it out through that avenue rather than expecting an official return.

Died before it's time. It it very hard. This game still does things that Star CItizen does not do after over a decade and 1bil in sales. So I feel the devs of this game need a HUGE pat on the back. Check out the Hellion Rescue Project.

What a gem of a game, too bad they delisted it and there's no way to play it anymore if you didn't get if before. I recommend using the Hellion Rescue Project mod, it fixes a few bugs and makes the UI more intuitive.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
