Helium Rain


A space sim that doesn't cheat

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.

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.


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.
