Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Universe Sandbox ² is in active development, but it's already a fully-featured, stable, and smooth-running space simulator. And it now officially supports VR with an HTC Vive or Oculus Rift+Touch.

We're proud of what we have to show, and we know many fans are eager to explore and experiment with the universe.

We're constantly working on features, improvements, and bug fixes, and we release frequent updates.”

Approximately how long will this game be in Early Access?

“It's hard to give an accurate estimate. Building a universe simulator is a job that's never complete.

We have a long list of features and improvements that we're very excited about implementing, and which will keep us busy for a long time to come.”

How is the full version planned to differ from the Early Access version?

“Some of the features and improvements we'd like to add:
  • Space megastructures
  • Basic life simulation
  • More dynamic terraforming & improved climate simulation
  • Better collisions on a wider range of scales
  • Missions and objectives
  • Steam Workshop support
  • Achievements
  • Language localization
  • Improved human scale mode
  • More intuitive VR experience with features equal to desktop version

What is the current state of the Early Access version?

“Universe Sandbox ² has been in development for almost five years, and for the past two years, we've had users pouring hours into testing, exploring, and enjoying the sandbox. It is already a fully-featured, stable, and smooth-running simulator.

We've fixed most of the serious issues and have made a lot of progress on optimizations for a range of hardware. Because it is a large-scale sandbox, though, it does have its share of bugs and could use polish in some areas.

The VR version of Universe Sandbox ² is a relatively recent update, and we are working to add many of the features and optimizations already found in the latest desktop version. Our next VR update should address this. After that, these two versions will be merged and shouldn't require separate updates.”

Will the game be priced differently during and after Early Access?

“We have no plans for changing the base price of Universe Sandbox ² at this time.”

How are you planning on involving the Community in your development process?

“We actively seek community feedback from the in-game feedback as well as from our forums and social media.

Community feedback helps us prioritize our long list of planned features and focus on fixing the worst bugs and issues. We make an effort to address every issue that comes our way.

We also add simulations and features based on community requests, like the recent addition of custom-colored planets, and an index for the likelihood of life on planets. We also recently added a tool for easily recording and sharing GIFs on social media.

In the future, we plan to integrate Steam Workshop for user-generated content, like custom models, and for easily sharing simulations.”

A New Exoplanet & Interstellar Messenger | Update 20.3



Update 20.3 features two new simulations for the recently discovered exoplanet, Ross 128 b, and the first observed interstellar visitor, ‘Oumuamua. This update also includes a number of smaller improvements and bug fixes.
 
Ross 128 b

On November 15, 2017 astronomers with the European Southern Observatory (ESO) discovered Ross 128 b, a potentially habitable, Earth-sized exoplanet orbiting a red dwarf star 11 light years away.

Though Ross 128 b is farther than the closest temperate planet, Proxima b, it orbits a “quieter” red dwarf that emits far less deadly ultraviolet and X-ray radiation. This makes it a much better candidate for habitability.

Learn more on ESO’s website.

‘Oumuamua

On October 19, 2017, astronomers in Hawaii observed an asteroid soaring past Earth. Analysis of its trajectory revealed that it is the first interstellar object ever observed in our solar system. Nicknamed ‘Oumuamua, meaning “a messenger from afar arriving first,” the asteroid carries the story of a distant star system born a long time ago.

Learn more about ‘Oumuamua on NASA's website.

Universe Sandbox ² Featured in Latest Vsauce Video


Friday, November 3rd: We've released Updates 20.2.3 and 20.2.4, which add two sims from this Vsauce video as well as a few improvements and bug fixes. See the sims in Home > Open.

Hey, did you hear that? Michael from Vsauce just gave some high praise of Universe Sandbox ²: “This simulator will blow your mind. I love it.”

Vsauce is a science and education YouTube channel that has attracted over 12.5 million subscribers with “videos that feed the curious and illuminate the amazing.”

We’re very honored and humbled to be featured in their latest video! Check it out below.

About This Game

Universe Sandbox ² is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.

It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. Universe Sandbox ² is the long-awaited sequel to the original Universe Sandbox.

Universe Sandbox ² includes the desktop version and a VR mode with support for the HTC Vive & Oculus Rift+Touch. This is a free, automatic update.

Simulate Gravity

N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.

Collide Planets & Stars

Epic, mind blowing collisions of massive planetary bodies.

Model Earth's Climate

Watch sea ice grow and recede with the seasons because of the tilt of the Earth: change the tilt and change the seasons. Or move the Earth farther from the Sun and freeze the entire planet.
Learn more...

Terraform Planets

Add carbon dioxide to a planet's atmosphere to heat it up. Then add water...

Deform Surfaces

Impact planets with asteroids and comets and leave behind massive, molten craters.

Supernova a Star

Make a star evolve by cranking up its age or mass, then watch a supernova unfold.

And more...

  • Historical simulations - ride along with Juno, New Horizons, & other spacecraft
  • Material System - build planets out of Hydrogen, Iron, Rock, & Water
  • Solar flares & volatile trails
  • Procedurally generated stars & planets
  • Pulsars
  • Light-warping black holes
  • Dark matter
