What do I get?

Buy Universe Sandbox ² now to get instant access to the Early Access version and a pre-order for the final release.


You'll receive a Steam code to add Universe Sandbox ² to your Steam Library. Steam is free and automatic updates mean you'll always have the latest version.



Universe Sandbox ² is still in active development. We're not done fixing bugs, implementing features, and adding polish. But there's already a lot to explore, and every update introduces improvements. There are many more to come.




If you're an educator, you can purchase Universe Sandbox ² at a discount through TeacherGaming.


Instead of a Steam code, you will receive a standalone version of Universe Sandbox ². You may also use this option if are not an educator and you'd like to purchase a standalone version at the full price. Please note that you will need to manually download updates as they are released.
