About Helium Rain

✦ AI summary

Helium Rain is a single-player space simulation where you build a spacefaring company by trading resources, commanding fleets, and conquering a procedurally-generated star system. Master both real-time Newtonian combat with detailed ship systems and long-term economic strategy, where every decision from destroying a freighter to declaring war ripples through the simulation's complex, interconnected world.

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...
  • 13 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 Newtonian flight, localized damage and joystick support
    There is no speed limit in Helium Rain. You can fly at half a mile a second while aiming backwards. Aim for critical systems in order to disable ships, kill their crew or capture targets, and don't fly into asteroids.
  • Complex economy model
    Take advantage of a complex simulation of space trade to be the most competitive company.
  • 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.
  • Quick-action skirmish mode
    Setup your fleet, pick an opponent and go into fighting action right away !

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, with the potential to cause an economic crisis.

Its such a great game! I wish I could still support the developer, but it seems they retired. I truly appreciate that the developer open sourced it.

I really like this game. I also like truck sims, so it makes sense. Added a couple mods from the workshop and I'm really enjoying it.

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.

Planet Zoo 2 price: which edition, and when it gets cheaper

Planet Zoo 2 is out today. The Planet Zoo 2 price splits two ways, the cheap pre-order keys stopped existing three weeks ago, and the original got dearer as the sequel landed.
