Universe Sandbox was removed from Steam on November 4th, 2016. At that time its price was reduced to $0.00 meaning the page is still accessible on Steam today but the game cannot be purchased. Through February of 2017 the “Legacy” edition of the game was available to download directly from the developers site but was later removed with a note that “Universe Sandbox Legacy is no longer available for purchase or download”.

The game appears to have been removed to encourage purchases of the follow-up, Universe Sandbox². On August 24th, 2014 the following message was pinned to the Universe Sandbox discussion page on Steam:

“Universe Sandbox ² is a complete rewrite of the original. In development for 3 years, it features improved gravity physics, collisions, climate, material compositions, stellar evolution, and supernovas.”


About the Game

Universe Sandbox Legacy is an interactive space simulator for Windows-based PCs first released in 2008.

Unlike most astronomy software that just shows you what the sky looks like or where the planets are, Universe Sandbox is a powerful gravity simulator. You can add another star to our solar system and watch it rip the planets from their orbits.
