A downloadable game for Windows

The game is set in the far future where our star, having exhausted all of it's hydrogen reserves, begins to turn into a red giant and engulf the inner planets. Harvest moons for metal and fuel, evacuate as many planets as you can and try to help humanity escape their dying sun.

This is an expanded version of the original game made in 7 days for 7DRTS.


The aim of the game is to evacuate the colonised inner planets to the safer outer planets, with the ultimate aim to build an interstellar colony ship. You can build Deuterium and Metal Mines on moons in order to gain the resources required to build ships and buildings on the planets.

Buildings / Ships

  • Deuterium / Metal Mine - Mines for Deuterium / Metal
  • Small / Large Colony Ship - Used for transporting people to other planets
  • Terraforming - Used to Make the colder outer planets more habitable.
  • Solar Mirrors - Slows population loss from the effects of solar radiation.
  • Fusion Inhibitor - Temporarily stops the sun from expanding
  • Interstellar Colony Ship - Allows you to transport the human populace to a new star system.

This was beautiful makes we wish I could play some more :)

I only managed to save 350 million people out of the billions I start off with. Their sacrifice will not be forgotten :'(

Part of me wants to download the code and see if I can make it so you can keep playing in that new solar system and have the sun start to expand after a few minutes


Amassing game, could extend and start something that could be a lot more in depth


I can't move the ships.


Right click on the planets. Don't right click on the moons, I made that mistake.


Wow, I guess I'm a couple years late to the party, but this is a very beautiful, compelling game that desperately yearns for an expanded version.  Can I give someone money to do that?  Here, take it.


Wish this was still in development.


Cool game.

Thanks, glad you enjoyed it :).

A great suspenseful game. Really enjoyed it :D
