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 more recent update, and we are working on adding more features and functionality to match the amount of control and fine-tuning that is possible in the desktop version.”

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

“The price will probably increase in the future.”

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.

We are actively working on Steam Workshop support, which will open up doors to community-created simulations. Further down the line, we plan to also support sharing of custom models and textures.”

Support for Multiple Languages Is Coming Soon

https://www.youtube.com/watch?v=uE4suCpQkoQ
A few weeks ago we talked about our upcoming support for Steam Workshop, a feature we've been working on in parallel to our work on Update 21's big features, Planet Grids & Lasers.

Now we're excited to announce another upcoming feature for Universe Sandbox ²: support for multiple languages. As with Steam Workshop, we still have work to do on this, but we've made great progress. Just check out the video above for proof. You may spot some words that haven't been translated yet, and some things may look a bit off, but all the big pieces are in place and everything is working smoothly.

If you're familiar with any of the languages used in the video, you may also note that some translations are a bit strange. Currently, everything has been translated with Google Translate, which has been a very useful tool, but it does not always produce the most accurate results. In the future, we’ll have professional translations for the most widely used languages.

Help Translate
Universe Sandbox ² is constantly growing and evolving; it's important that we have help from others to build and maintain translations into any number of languages. This is where you, the community, come in.

Along with the ability to switch languages at any time, you will also be able to help translate Universe Sandbox ² with a very easy-to-use integration with Crowdin. Crowdin is a system that helps manage localization projects by making it easy for anyone to submit new translations and vote on the best ones.

Once we have everything ready, we'll be sure to make an announcement and include full instructions for anyone who wants to help.

Please note: Localization is not yet available in Universe Sandbox ². It is still a work-in-progress feature and will look different in the future.

Big thanks to our developer, Dave, for all of his work on supporting other languages. We’re excited to make Universe Sandbox ² more accessible to people all over the world.

Steam Workshop Is Coming Soon

https://www.youtube.com/watch?v=kPFbcAcwS-c
We’re still hard at work on Update 21 and its two big planned features, Planet Grids & Lasers. But as promised, we’ve also been working on some other things at the same time.

For one, we are making great progress on support for Steam Workshop. It’s not quite ready, but we’re excited to share our progress with you, and even more excited about the possibilities this opens up once it’s released.

When we launch Steam Workshop, you’ll be able to easily share your simulations with the community and explore simulations created by others. Further down the line, we plan to add support for custom models and textures, too. Support for mods on Steam Workshop may eventually come, but not anytime soon.

Please note: Steam Workshop is not yet available in Universe Sandbox ². It is still a work-in-progress feature and will look different in the future.

Thanks to our developer, Jonathan, for all of his work on Steam Workshop!

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 includes the desktop version and a VR mode with support for the HTC Vive & Oculus Rift+Touch.

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 that leave behind molten craters.

Create Solar Systems

Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.

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.

Supernova a Star

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

Explore Historical Events

Ride along with the Juno and New Horizons spacecraft, or view a total solar eclipse.

Throw Planets in VR

Just grab and fling.

And more...

  • 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
