“Helium Rain will stay in Early Access for around six months, depending on the volume of feedback we receive.”

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

“We want to add new content, keep polishing the game, and add new gameplay mechanisms if players request them. Specifically, we are planning on several important features.

  • Story
  • Fuel usage simulation
  • Engine ISP simulation
  • New navigation system
  • New areas to explore
  • New ships to fly
  • New tutorials

What is the current state of the Early Access version?

“The Early Access release features a fully-playable sandbox.

  • Spaceflight gameplay
  • 30 areas to explore
  • 12 flyable ships
  • Dynamic contract system
  • Technology system
  • Game tutorial
  • Joystick support in flight
  • Windows and Linux support

We have been play-testing it for months, and we believe it is already a quality product.”

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

“We will raise the price slightly when exiting Early Access.”

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

“We have been involving the community for quite some time, and will be happy to keep doing so.
  • We have a public bug & feature tracker at, where we've been tracking suggestions from players.
  • We will listen and respond directly to feedback on the Steam community forums and our dedicated subreddit.

Update Roadmap

Let's talk about where Helium Rain is going !

It's been three weeks since the game came out, and we're now to the point where most game-breaking issues are solved - we know some bugs are still there, but it's no longer an urgent situation. We've looked at every suggestion on the forums, discussed what was more important, and we can now share a roadmap for future updates !

Modular stations
Our first update will be a player-suggested one : modular stations.

We're working on a second station update, after the big graphical changes two weeks ago. Now we want to add a new station-building option : instead of creating separate stations, companies will have the option to build station hubs, a shipyard-size stations that acts as a large docking pad and support station. This station will feature a unique perk : stations can be built on it, in a branching structure, removing the need for ships to transport resources between factories.

Along with this huge feature, we'll rework the pricing model of stations, allow companies to scrap them just like ships, and add a few more UI elements.

Updated economy
The next item will be less visible, but will change the game a lot. We're aware the economy right now is very rigid, with little pricing variation and a number of issues with how companies react to resources. While the changes there are not fully decided, the overall plan is to make the economy much more liberal.

Along with economy change, we'll try to add much more information in the menus to make the game less obscure.

Fuel management
This one was planned before we launched. We still plan on adding a fuel usage model, which would reward careful piloting, make engine upgrades more useful, and generally improve the immersion.

The fuel update will come with an updated orbital map, new engines, possibly a new ship !

Story and contracts
These updates will be quite large, and as a result, the story has lost some priority. We haven't heard anyone asking about it, so we don't feel like the story is very important for players. It will come after the large features that we feel the game really need.

Skirmish mode
Last but not least : another player suggestion, the skirmish mode, will come to Helium Rain. It will be separate from your regular game save, will offer tools to configure a battle and start fighting right away, without endangering your precious ships !

Keep telling us your ideas
This is a rough outline - we'll keep updating you with how the planning changes. The general idea is that we want the core game to be perfect before we start adding elements that don't impact the everyday experience.

While we may not reply to everything on the forums, rest assured that we do read everything. We're focused on improving the game and keep doing Early Access right.

Thank you for your feedback, and keep telling us what you'd like us to do next !

Stations update

We've released a new version for Helium Rain. Every station currently in the game has been remade, and a number of issues were fixed - mostly to the AI and economy models in the game. Some rendering details were also improved.

New stations
Stations are now twice larger at least (solar power plants are especially large) and feature a billboard system to show off which company they belong to, or to show advertisement for other companies. The player stations will always proudly show off your might !

Adding this much content required balancing against performance - we drastically reduced the triangle count of many station components, usually by a factor of more than two. The game should actually perform slightly better now.

As a result of the new stations, we have to warn that ships flying close to a station and not docked at it when the patch is applied could be damaged. Ships docked to a station will be unharmed. We generally have a policy of never breaking game saves during and after Early Access; we hope that this exceptional disregard for safety will not harm you.

Economy fixes
While this update is mostly about stations, we also fixed around 20 issues. Most issues were tied to our extremely complex economy model. If you want to read up on how complex it really is, take a look at this economy primer by Niavok, our gameplay programmer. We know some issues are still outstanding - little variation on pricing, complicated end-game situations, expensive stations - and will be working on fixing that with future updates.

We've also made a decision on the topic of manual docking. This divisive feature had some players refund the game, and some others praise us for it. We had to make a compromise and decided to keep manual docking in the game, but to make the unlock of the auto-docking technology free as soon as the game starts. Players who elect not to use the auto-docking can get another technology for free instead.

State of Linux support
Finally, we are aware that many Linux users with AMD hardware are still suffering from issues with the game. This is a very serious problem for us, one we have little solutions for. We will release a beta version of the game in the upcoming days, built with an updated Unreal Engine 4. We hope that this will start resolving some of the issues.

The beta will also be available for Windows users who want to try an untested version that might bring more performance, at the cost of possible issues.

The full changelog is available here as usual, for those of you who want to know what we've really been up to. We thank all the players who offered their feedback. Please keep doing so, and have a great time with Helium Rain !

About This Game

Build your fleet, trade, explore and conquer

Helium Rain is a single-player space simulation that places you at the helm of a spacefaring company. Trade resources, buy ships and stations to fulfill contracts ! Dock at stations to buy and sell you wares or upgrade your ship, upgrade your technology to be more efficient and militarize your fleet to prevent piracy.

You will need to master both real-time action and long-term strategy: destroying a freighter has a direct impact on the economy, while declaring war will make your spaceflight environment slightly more hostile...

A world that feels real

Your ships have generators, radiators, weapons, engines, cargo bays or life support systems - they all work together. Every thruster on your ship plays a role. Aim for engines to pin down your enemies, or send them spinning around by destroying power stations. Most ships have more than thirty individual parts ! You can customize the most important parts of your ships - your main engines, attitude control thrusters, weapons and hull colors.

Your competitors are independent factions, companies with the same goal as yours - ruling the system. They will try to undercut you, or even attack you if you become a threat to them. But don't be too quick to destroy them, as war can break the supply of resources you depend on ! Attacking freighters will destroy resources, making them costlier, with the potential to cause an economic crisis.

  • 12 playable ships with weapon and engine upgrades
    Build and fly fleets of fighters, bombers, cargos, corvettes or capital ships. Buy new engines and weapons.
  • Fast-paced combat with a Newtonian flight model, full joystick support
    There is no speed limit in Helium Rain. You can fly at half a mile a second while aiming backwards. Beware of asteroids.
  • Realistic economy model
    Take advantage of an accurate simulation of space trade to be the most competitive company. If diplomacy fails, blockades are in order.
  • Localized damage model for spacecrafts
    Aim for critical systems in order to disable ships, kill their crew or capture targets.
  • A planetary system to explore
    Explore around 25 sectors orbiting the gas giant Nema and its moons.
  • Procedural contracts, world exploration, technology upgrades
    Pick contracts and build your empire to become the largest company.
