Helium Rain is a realistic space simulation game.

A space sim that doesn't cheat[edit | edit source]

The massive gas giant Nema is your new home. Surrounded by rings of metal and rock, the planet is a near-infinite source of fuel. Helium Rain gives you an empire to build and defend against your competitors. It's up to you to decide if you will trade resources, avoid trouble, or start wars.

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


Helium Rain is a game where everything is tied together. Ships and stations are built with resources that need to be mined, transported and traded. The steel you sell to a company will become a ship or a gun. The cargo you're blowing up will create a shortage. The blockade you're imposing will raise the prices. Helium Rain simulates a complex economy where all actions have consequences.

Spaceships[edit | edit source]

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 the ships have more than thirty individual parts to target. You can customize the most important components - your main engines, attitude control thrusters and weapons. You can choose your colors, emblem, and of course, you can fly every ship in the game.


The physics of the game are highly detailed. Power-hungry components will glow red hot when cooling fails, ships and stations can be pushed or thrown out of place, and gun shells have complex trajectories.

Open-source development[edit | edit source]

The development is tracked on our public issue tracker. You can see the work being done, the features we want to add or the bugs we know of.

The game's full source code is available on Github under the MIT license. Feel free to read the code to look for interesting stuff for your own game.
