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.”

Ending Support for DirectX 9 & 32-bit Windows Systems

 
Universe Sandbox will no longer support Windows users running DirectX 9 or 32-bit operating systems later this year. The exact date and release are not known at this time, but we want to give everyone a heads-up.
 
Why?
 
Short answer:
These are technologies that have been replaced in mainstream computing over a decade ago. There are very few users left on these systems, and it is getting harder to support them as time goes on. This will help us continue to make improvements to performance and stability into the future.

Long answer:
The game engine we use, Unity3D, stopped supporting the DirectX 9 API last year. Unity states that "due to diminishing hardware numbers and the loss of platform support from Microsoft ... continued support of the DirectX 9 API is no longer feasible and is working against the development of new features in Unity." This move mirrors the direction taken by many other companies for their software and video games, including Blizzard's popular Heroes of the Storm.

The same is true for discontinuing support of 32-bit OSes, as hardware manufacturers like Nvidia are no longer updating 32-bit drivers with new features, Apple is gearing up to drop all support for 32-bit applications, and World of Warcraft is now going to be 64-bit only.

The vast majority of Universe Sandbox users are already running 64-bit, and our ability to focus on and develop only this version will help us continue to make improvements to Universe Sandbox's performance and stability into the future.

 
Who Will Be Affected?
 
This will not affect macOS or Linux users, and if you are on Windows, chances are good that you are already running modern hardware with support for later versions of DirectX and a 64-bit OS that will not be affected by this.

But in case you aren't, here's what you need to know:
 
What Should I Do If I'm Affected?
 
Upgrade to a newer version of DirectX:
We recommend upgrading to at least DirectX 11. Follow these instructions to find out which version you're running and view information about upgrading, if needed.

Some older GPUs do not support DirectX 11. You will need to find information about your GPU or contact the manufacturer to see what versions of DirectX it supports.

Upgrade to a 64-bit OS:
If you're running Windows 7 through 10, you're able to upgrade to 64-bit for free. Here is one guide for upgrading Windows 10.

You will need to upgrade to a newer version of Windows if you are running a version older than Windows 7.
 
If you can't upgrade:
We will offer a DirectX 9, 32-bit compatible version of Universe Sandbox via Steam. This version will not continue to be updated or supported; it will be the last update before we move onto DirectX 11, 64-bit versions only.

If you have any questions or concerns, please contact us.

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, and Windows Mixed Reality.

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 Your Own 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
  • Stellar flares & volatile trails
  • Procedurally generated stars & planets
  • Pulsars
  • Light-warping black holes
  • Dark matter
