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 #48 Economy

Everyone faring alright in the great void, any problems? Nothing to worry about, just make sure you have your welder, gun, ammo, batteries, drill, spare cans, jetpack, a backup weapon and stimpacks on you at all times and you should be fine. Right? Yeah… that’s a lot of gear to carry around… So this time we are going to talk a bit about economy and itemization in Hellion.

Basic resources

Or consumables if you like, are all essential things your character can’t function without. No oxygen and you’ll suffocate, no fuel and you won’t be able to move. Unlike other settings where movement requires little or no effort, vacuum as you all know, is a bit different. Early on in the game’s development we realized that building gameplay solely on “survival” mechanics wasn’t quite cutting it. Say we chose to deprive players of the most basic resource like fuel. That’s it you’re dead… It won’t matter if you have enough power or oxygen, if you can’t move you’ll die eventually and the only option left to you is to activate a distress call and wait… Not particularly engaging, or fun for that matter.

Sure, we could have just added a myriad of different problems that force you to “eat, sleep and drink every 15 seconds” but that also didn’t sit right with us. As things stand Hellion is a game with somewhat slower pace and we felt that adding all of these problems would turn gameplay more into a chore than something fun and engaging (one of the reasons why we’re removing degradation). We want players to “create their own problems”... in a manner of speaking. Every time a player ends up in a tight spot we want to give them a “way out” and in case they don’t make it… Every player needs to know how they ended up in that situation, why they died and most importantly how to prevent it.

Crafting 2.0

As we’ve stated in our previous blogs space radiation and armor are coming to Hellion and with them a completely new exploration and survival experience. To spice things up we’ve also revamped our crafting system with new resources and blueprints. In order to craft any item you will now require a minimum of 2 things. A blueprint and some crafting resources.


All characters start with a set of basic tier 1 blueprints which include items like suit, jetpack, helmet, nanite core, warp cell, drill and similar items. These are all things that your character will need in order to survive when starting out. In order to craft other items or higher tier versions of the ones you already have you will need to find a blueprint.

Blueprints can be obtained by dismantling items in the fabricator module. Items dismantled in this way will award you a blueprint for that particular item but will not provide any crafting resources.

Blueprints are also tied to a character on a particular server, so even if your character dies and you lose your base the blueprints you obtained will stay with you even if you select a “fresh start”. The only way to lose blueprints is to delete your character from a server completely.

Crafting Resources

As the name implies these are the resources necessary for crafting. They can be divided into two categories: recycled and refined resources. Both can be obtained by recycling items in the fabricator module, but these will only award a fraction of their crafting cost. To recycle any item you will need to use the fabricator’s “shredder”.

Altair Corporation takes no responsibility for any severe injuries, mutilation or death resulting from improper use of the Shredder™

As before “scrap components” such as broken armature or shattered panels remain the best source of recycled resources and they can be easily obtained from the junkyards. There are four recycled resources and they are, in order of rarity: Carbon Fibers, Alloys, Circuits and Superconductors.

The second category of resources you will need are “refined resources”. These are most easily obtained by mining raw resources from asteroids and refining them using the cargo’s refinery. Resourced that you can mine and their refined counterparts are: Ferrite > Nickel-Iron, Mafic Rock > Silicates, Titanite > Titanium, Rare Compounds > Rare Elements.

Rarity and zones

Rarity of any given resource represents the amount of effort needed to obtain it and not just “how often you come across it”. Rarer resources will often be located in deadlier debris fields and zones with higher radiation, requiring players to craft better gear. While it is possible to obtain these resources with inferior equipment it is very risky.

Not only will different zones (planets and moons) have different resources, the resources you find will also vary in quantity. Some areas will offer better mining opportunities while others an abundance of salvage. You might find yourself planning a trip to one of the planets or moons, simply because it has the highest concentration of the resource you want.

To make things a bit more interesting basic consumable resources won’t be readily available everywhere you go. They will be plentiful in the starting area, but Ice and Dry Ice for example will become scarcer and scarcer as you move closer to Hellion’s blazing heat but abundant around frozen gas giants. Similarly, Regolith which is the sole source of He-3 consumed by the reactor becomes more and more plentiful the closer you get to Hellion but is virtually non-existent in outer regions.

Itemization and Equipment

This finally brings us to equipment. Most items in the game now have tiers just like parts. An item that is one tier higher requires additional “rarer” resources to craft but also offers substantial bonuses over its lower tier counterpart. Different nanite cores will offer improved armor necessary for mitigating damage in dangerous debris fields or high radiation zones while different suit types will offer different protection values against radiation and gunfire. In both cases higher tiers will exponentially improve your survivability. Better weapons and ammo will be more expensive but offer advantages needed to overcome stronger turrets. Better mining gear will help you extract resources faster which becomes crucial when mining an asteroid on a doomed orbit.

Now to address the number of items you need to carry around with you, as mentioned in the beginning. Higher tier items will also indirectly optimize your loadout. If you invest time and effort into a better suit with higher oxygen capacity, carrying cans becomes redundant. Same can be said about raw canisters, batteries and hacking tools freeing up inventory slots for additional stimpacks, ammo or anything else you might need for the task ahead.

Everything above leads to one thing. No matter where you choose to go, or what you decide to do, there will be a challenge to overcome, but you will always be able to plan ahead. Will you postpone that trip to Askatar until you craft better equipment or, rely on your piloting and EVA skills to compensate? How high you decide to raise the challenge bar is up to you.

Finally, as you may have guessed already, when it comes to blueprints and items, having a blueprint is only useful if you have access to the resources necessary to craft it. For some players using the item will be better than dismantling it for a blueprint, but the risk here is that they might lose it. What if you traded someone for the resources or blueprints that you need? Or… stole them from someone… The choice, as always, is up to you.

Oh and we almost forgot! Expect this update to land in around two weeks, as soon as we are done with balancing and bug fixing. That’s all for today!

Until next time, fly safe!

Devblog #47 - Space Radiation and Armor

Fellow explorers, we salute you! Today we’re going to go in depth about one of the features of the next update that was only hinted at in the previous posts. So tighten the seals on your EVA suits and check your fuel levels, because we’re going to talk about space hazards, armor and maintenance.

We’ve always thought of Hellion as player versus environment kind of game. While this concept is used in many games, in Hellion it is a bit more literal. Space is extremely deadly, that much is obvious, but with the right gear life in complete vacuum is possible. For as long as the technology works that is. Even the smallest malfunction can cause complete chaos, as evident from the many space missions launched during the last century. Hellion’s basic premise was always, what happens when our technology starts failing and ‘ordering a replacement’ is no longer an option?

In Hellion, technology failed a long time ago. When players wake up, they find themselves surrounded by ruins and decaying equipment. Most of the modules and ships you come across went well past their ‘expiration date’ and would have been decommissioned decades ago under normal circumstances. But as we know, the world of Hellion is anything but normal and you find yourself in a situation where all of your gear needs constant maintenance just to stay in one piece. So the question now is: What is causing this decay and is there anything you can do to stop it?


Degradation was always a placeholder, something to tie things up until we implement a proper system. In retrospect we may have clung to it a bit too long. Finding a broken down module and restoring it to working condition is certainly fun and offers an interesting activity. Same can be said about getting hit by a stray piece of debris that creates a crisis situation that you have to resolve.

But the key problem here is that players have no control over these events and no way to mitigate the damage their ships and modules take. All they can do is pull out their welders and start repairing…

Space radiation

First we want to announce that we’ve put “arbitrary degradation” on a one way shuttle out of the Hellion system. Yup, it’s gone. For good this time. No more “walks of shame”, mandatory repair duty and gameplay that feels like a chore instead of being fun and engaging. We are introducing a new system, one that offers a lot more control to players.

Introducing “Space Radiation”. This is a combination of “direct EM radiation” and “ionizing radiation” present at any location in the Hellion system. In short, any orbit you choose to go to will have a radiation value that represents how much damage your ships and modules will take each second while in the area. A separate value also exists for players and will tell you how much damage your character will suffer each second while outside of a ship or station.

Radiation will increase expontially the further you move away from the “sweet spot” of the starting zone.


No system of damage would be complete without a way for players to somehow prevent or at least reduce that damage. For this purpose we are introducing several new parts for ships and modules, as well as armor values for player suits. Armor acts as a direct counter to “all forms of damage”, not just radiation. It will prevent incoming damage up to its maximum value. Any excess damage will be applied directly to module/player health.

Nanite Diffuser and Nanite Cores

A new “nanite diffuser” system is now present in all ships and modules. It requires a new part: the “nanite core” in order to function and will reinforce the module’s hull by adding a layer of armor over it. Any incoming damage that is lower or equal to the armor value will be applied to the Nanite Core instead of the module.

Cores have four quality tiers that can be crafted and come in two variations: AltCorp (civilian) or SDS (military). Civilian cores offer lower armor but exceptional durability (effective HP) compared to their military counterparts. They are designed to shield your modules from harm over long periods of time in relatively “safe” environments. Military cores on the other hand offer exceptionally high armor but low durability as they are designed to shield your ships during excursions into debris fields and from minor collisions. All cores are fully interchangeable and can be used in both ships and modules.

Player Suits

Extra Vehicular Activity represents a huge chunk of Hellion gameplay and we wanted to spice things up with the new radiation system. All suits now have different armor values according to their purpose. The Mk9 pressurized suit offers a decent “radiation armor” value but has added protection from weapons and turret fire, making it ideal for scavenging and raiding. The EVA suit on the other hand features higher radiation protection and collision resistance but no added protection against weapons, making it ill suited for any combat scenario. Also, both suits have four quality tiers.

Hazard Zones

With radiation and armor in place we are also dividing Hellion into hazard regions. These regions will offer different gear and resources but will require certain prerequisites to be met before they can be safely explored.

This is where the part about “player control” comes into play. With enough information about zones players can easily plan ahead and collect gear and items for the task ahead of them. Want to set up a base in the relative comfort of the starting zone? Civilian cores will get the job done. Want to reduce the amount of maintenance you do? Find or craft higher quality cores. Planning a salvage run through Athnar’s junkyards? Better obtain some high tier military cores, that debris hits hard. Expecting turrets on that doomed outpost? Bring a better suit.

Every time players choose to do an activity, there is a risk factor involved. Entering a high hazard area with inadequate gear is highly lethal but possible. And it creates that high risk / high reward scenario. Whether or not players survive is up to their equipment and more importantly their skill.

That’s all for today folks! Until next time, watch out for turrets and 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)…
