A realistic space opera for PC.

Explore the vast emptiness of space. Take command of your ships, create your empire.
Helium Rain is a realistic space simulation game.

  • Fly any ship of your fleet, including fighters, freighters or capital ships.
  • Do as you please, whether you want to become a wealthy merchant or a fierce pilot.
  • Customize your ship, change your equipment, buy new gear.

Hard Sci-fi

We want to build 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 of our ships have more than thirty individual parts !

One planet, many enemies

The massive gas giant Nema is your new home. The planet is a near-infinite source of fuel, her orbits a swarm of asteroids, her irradiated moons a silent threat. Helium Rain gives you an empire to build, but you will need to claim it for yourself, and defend it against your competitors. It's up to you to decide if you will trade resources, start wars, or just avoid trouble.

Customization

You can customize the most important parts of your ships - your main engines, attitude control thrusters and weapons. You can choose your colors, and of course, you can fly every ship in the game.

PC graphics

Helium Rain is built with Unreal Engine 4 and targets the most powerful gaming rigs. The game will ship with support for 4K rendering, supersampling, high-quality shading and post-processing effects.

It's been more than a year since we announced our release into Early Access, and it's been more than four years since we started working on our realistic space sim. Now, the time has come for a final release on Steam, as a polished and complete game. Take a look at our new trailer first !

Helium Rain is a realistic space sim that blends trading, strategy, and realistic spaceflight action. As an empire-building singleplayer game, you control a spacefaring company that could rule an entire planetary system - if you can make it happen.

Station

A tale of many changes

We've released no less than twenty updates since August last year, some small, some huge. We entered Early Access with a small and vague roadmap, planning on a few months of updates before a final release ; but we underestimated just how many ideas our players would have. Here are the largest changes.

  • Upgraded stations with larger models and better docking
  • Modular station complex to easily organize your production
  • New combat model with a quick-play skirmish mode
  • New economy tools, including a transaction log, company finances
  • Upgraded economy simulation
  • Meteorite interception contracts
  • Nicer graphics, UI, sound
  • Gamepad & joystick support
  • Bugfixing

In short, every aspect of the game has seen an update - all of them based on player feedback.

Changes that didn't make it

While we're happy at Deimos Games with the state of the game, I have to recognize that two large planned features didn't make it to the final game - a planned storyline, and a fuel management system. Both elements were initially outlined, but were not implemented.

The first dropped feature, the story, was planned as an optional, long-term quest chain toward end-game action. We never had a clear plan on how it would have played out, but we started creating story-focused areas, and we had various ideas about new enemies that would pop up. Ultimately, we decided the work on the economy was much more needed, and larger than anticipated. The story sectors have been made a regular part of the game and can be explored for research points.

Habitat station

The second item, fuel systems, did not get nearly as much work, and was dropped when it became clear it wasn't in line with what players wanted. Fuel management would have added yet another layer of resource management, it would have created nasty situations of stranded ships, it would have made the economy less stable, and warfare would have had even great risks of breaking the game. We decided it wasn't worth the added realism.

Ice field

While it's never enjoyable to abandon elements of a project, we feel like we used our resources efficiently during Early Access. As a very small team working for many years, we decided to focus on the core of the game - an economy simulation that works well and gives agency to the player, with combat and exploration elements.

We're still here

Releasing out of Early Access, two weeks from now, will mark the end of large additional features. But we'll still be on the lookout for bugs, blocking gameplay problems, and player feedback. We're still very serious about Linux support or performance problems too. If you find an issue with the game, please do tell us about it !

In fact, we're currently working on an additional 1.1.0 update, bringing some final UI changes to improve your economy tools. A few problems with the recent Automated Fleets technology will be fixed too. Stay tuned for an update this week.

Fighting

As a final word for today, I'd like to thank the community for helping us succeed with this project. We couldn't have done it without you, and we hope Helium Rain is as good as we want it to be. Have fun !

That sounds good to me. I'm a little frustrated and tired of when searching for games, something around 70-80% of what I'd otherwise be tempted to look at are MMO-somethings....
