“This game was developed in Serbia.”

Early Access Game

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

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Hellion is an ambitious game that has been in development for almost two years now. Having completed the core gameplay features, we believe it is time to share the game with players before proceeding further with the development. One of the main reasons behind this decision is feedback. We expect that involving community this early in the development can only benefit the project. It is our opinion that Early Access provides an amazing opportunity for the community to contribute to the game that they like and want to play. Gameplay improvements, new mechanics and evolution of core features are only possible through open and honest discussion between players and the developers.”

Approximately how long will this game be in Early Access?

“Early Access will last for at least a year. At this time it is hard to estimate how long exactly. It will depend a lot on feedback as the scope of the development may change based on that. One thing is certain, early adopters will have a unique opportunity to watch as an entire solar system evolves before their eyes.”

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

“Full version of the game will have all the features found in our roadmap that can be seen here.
Three corporations to choose from, large fleet of functionally different ships, more planets and other celestial objects, detailed crafting system and a huge number of items – these are all planned for the full release. These will be implemented through regular updates over the course of EA. Also, we will constantly work on optimization and bug fixes in order to offer our players an exceptional gaming experience.”

What is the current state of the Early Access version?

“Hellion is in a state that clearly represents the idea behind it- an immersive gameplay with realistic physics and complex ship and station systems that require regular maintenance in order for players to stay alive. We believe one multipurpose industrial ship and the station building feature are enough for players to kick off their space adventure, while hundred players per server will guarantee a fun and interesting multiplayer experience. A lot of content has yet to be added, followed by polishing and more optimization. Also, we plan localization of the game to various languages in the near future.”

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

“As the amount of content increases the price will probably change.”

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

“Our goal is to work together with the members of Hellion’s community. We will keep our players informed of our plans and progress through our communication channels: Steam forum, our website, Facebook page, Twitter and Reddit. We will be listening to the voice of the community and are looking forward to constructive discussions aimed at creating the gameplay experience that we will all enjoy.

Devblog #39 - Story Mechanics

While our programmers are working on a multitude of bugfixes, optimization and even some new features we are not yet ready to reveal, our creative team puts its back into fleshing out and implementing the story of Hellion. So today we are going to talk about the way narrative will be handled in the upcoming update, scheduled to leave warp in November.

In our last blog we briefly touched on our decision to implement the story and also mentioned what the players can expect from the narrative. This time we are going to shed some light on the structure, mechanics, work we are putting into it and of course the story telling method.

Hellion’s narrative is broken down into chapters, or episodes if you like. Each episode is part of the larger main story and is thematically linked to certain locations within the Hellion system and told by characters that played a crucial role in the events that preceded the player’s awakening. Thus each chapter will be a story in its own right, but only a piece of the larger puzzle in the overarching plot. With each game update a new episode of Hellion story will be introduced.

Quests or missions represent the basic building blocks of the season and are centered around important characters and major events that shaped the Hellion system. Note that these are past events, rather than present ones and that they occured while many of the colonists were still asleep in their cryopods. Players waking up now are faced with the aftermath of those events, but that doesn’t mean that they are unaffected by them. The past still shapes the present and many of the problems players will be expected to face and overcome stem from the actions of important characters from the past. Understanding why they did what they did will play a crucial role in solving these problems.

To further help you in immersing yourselves in the world and its lore, all of the stories will be fully voiced. In addition we are adding voice overs and a plethora of new sounds to various interactions, warnings and events. Whether it’s a breach, power loss or a deadly debris field you will hear about it!

Quests come in many different shapes and sizes. From an immersive tutorial that will guide new players step by step, to large and complex plots where understanding the world and game mechanics will play a key role in figuring out what to do next. In case of the later category going an extra mile (or several thousand) may reveal details that would otherwise be missed, details that might prove crucial in the future.

Since Hellion is not a classic RPG, but rather a survival game, we wanted to inspire players to go into full role-playing mode by giving them a believable world to explore. Also, unlike the single-player action adventure games with a linear story-based experience, the world in Hellion is open for creative players that want to tell their own stories. This is why the story of Hellion will serve as a framework in which the gameplay occurs.

We are still talking about the 0.3 update because the official name is yet to be discovered during our long brainstorming sessions. If you have any blank suggestion, without knowing the content of the update, share it with us, maybe you’ll hit the target. :)

Devblog #38 - The Story of Hellion

“John was still deep in sleep when the first wave of pain washed over his body, then came the second one and the third until all he could feel was just sharp unrelenting pain. He opened his eyes and tried to scream but no sound came out. After what seemed like an eternity, the pain receded and his whole body loosened up as his dormant lungs filled up with air, for the first time in a century. Doors of the chamber opened and he stumbled onto the cold floor coughing. Emergency wakeup procedure, he remembered. He was still dizzy, from all the steroids in his system, but at least he was alive. The floor felt slippery beneath his fingers and it took him a lot of effort just to stand up. When his eyes finally focused, what he saw sent chills down his spine. The air was cold and thick mist shrouded the room while the flickering emergency lights gave it a hellish glow. Pieces of ruined wall padding and glass shards littered the floor while thorn cables hung loosely from the ceiling along with what remained of the covering panels. Cryopod to his left lay crushed against the opposing wall, thrown probably by the same force that almost tore open the module’s hull. He immediately knew why the floor was wet, there was no need to check for vitals.”

But who is John? What’s his background, how did he end up in this situation? How many characters opened their eyes inside a cryochamber and asked themselves, how on Earth did we end up in this mess, only to realize that something is missing? After all, it’s hard to roleplay when you don’t have a proper setting. What is the Expedition, what is Altair Corporation? How are they connected to SDS or what was their agenda? But most importantly, what the hell happened in Hellion? What could have caused such system wide devastation and why are we only waking up now after everything had ended… Or did it? What if there is yet a purpose for the survivors of Hellion? What if it was all part of a plan?

Up until now Hellion was but a blank canvas on which stories of many players were painted. We’ve enjoyed reading them on forums and we knew that if this sketch of a world enthralled so many players that we were probably on the right track. But we never forgot what we had promised when we announced the game. A story, a deep narrative permeating all the places you can explore and a history behind every doomed outpost and every derelict you’ve come across.

So far our development team has been working primarily on basic gameplay mechanics and the story was left on backburner. Starting with 0.3 we are bringing this aspect of Hellion into focus and starting the work on proper mission and progression structure as well as quests that will guide you as you uncover the events that preceded the first moment you opened your eyes in Hellion and saw a world in ruins.

We had never intended Hellion to be a one-time experience, where you get in the game, take a ride, kill some enemies and than leave. We had envisioned it as a unique experience that stays with us long after we’ve logged out and keeps playing in the back of our minds until the moment we log back in. We wanted to depict the frightening situation where people would wake up to find themselves all alone in the vacuum of deep space. A place where the future world became the world of doom. Survival was taken out of classic context and set in the most unforgiving environment imaginable, the one that none of us are familiar with. After all the oldest and strongest kind of fear is fear of the unknown.

Implementing a narrative in Hellion’s environment represents a big challenge for us, since our goal is to both paint the world and allow players to create their own personal stories within it. We hope that you will enjoy this new experience that will be coming to Hellion with the next update.

Until then, fly safe

About This Game

Hellion is a first person multiplayer space survival game.

It is a fusion of survival and space simulation genres that pits players against the deadly environment and one another. Survive in the harsh conditions of space and scavenge for air, fuel and other items necessary for survival. But keep in mind, you are not the only one out there. There are others, but will they help, or will they throw you to the void without a second thought? Remember, no matter how brutal space may seem, it cannot hold a candle to man.

Hellion is a solar system several thousand lightyears from Earth. Despite its distance, it is the target of the first interstellar colonization mission during the 23rd century. Almost a million colonists, suspended in cryogenic hibernation, leave Sol on a journey that would take many decades.

However, when they wake up, almost a century later, they find themselves trapped inside a nightmare. Instead of living in a manmade paradise, they are forced to fight for survival surrounded by deserted stations, incomplete orbital habitats and derelict warships.

With the closest rescue operation decades away, orbital economy in disarray and no authorities in sight, many turn to scavenging, stealing and outright violence. Few others try to live more civilized and begin uncovering the truth behind the largest disaster in human history.

Hellion is an ambitious project. It is an immersive world set in a solar system many lightyears from the comforts of Earth and is entirely based on the laws of Newtonian physics.

Hellion will make its debut as an Early Access game. EA version represents the basics of the vision behind this dark world. As our community grows and the player base expands, the game will evolve beyond these confines and become a true space survival that we can all enjoy. Open and honest communication between developers and community is the cornerstone of this idea. We are always open for discussion with our players as we believe that each and every one of us can add something to this project. Join us in the dystopian future that is Hellion and let’s build this world together!

Below is a comprehensive list of features planned for Hellion’s early access. Most of these are already in the game, some of them will undergo modification and improvement while others will be implemented during the course of Early Access (features marked as completed are the ones that will be present from the start and possibly modified and improved upon, based on community feedback)…
