Universe Sandbox ², the long awaited sequel, is now available on Steam

Universe Sandbox ² is now available now on Steam:
http://store.steampowered.com/app/230290/

Universe Sandbox ² is in alpha and very much unfinished, but it already blows away the original version with improved physics, climate simulations, material properties, terraforming, and awesome collisions.

We welcome you to join us on this journey as we continue to add and improve the sequel into the future!

“This is where Universe Sandbox succeeds brilliantly: players experience godly power to create or destroy, while almost unavoidably learning something about the physical properties of our universe.”
87/100 – PC Gamer

“Using the vast range of variables and tools at your disposal you can create some enormously convoluted displays of physics, bending cosmic laws to your will...”

Universe Sandbox ² Now Avaliable

Universe Sandbox, originally released in 2008 and on Steam in 2011, is no longer in development. We encourage you to check out our long awated sequel, Universe Sandbox ², now on Steam Early Access!

About This Game

Create and destroy on a scale you've never imagined with the ultimate space simulator.

Harness the power to create black holes, collide galaxies, and manipulate gravity with just a few clicks. Inspired by the software astronomers use to unlock the mysteries of our universe, never before has astronomy been so interactive or so much fun.

Spawn a massive moon to tear apart Saturn’s rings or launch a rogue star to rip the planets from their orbits around our sun. After unleashing catastrophic destruction, create your own solar system and share it with friends.

Turns out if Mercury were half as massive as the Sun, they'd do a little dance with each other across the solar system, obliterating everything in their path and sending Earth hurtling into the frozen abyss.
10/10 will make important scientific discoveries again.

*Opens 'Death Star Orbiting Endor' Sim.*
Me: "Wut?...That's just a moon..wait...I see what they did there. that's no moon...."

Play some AFX (Aphex Twin) music over this and just blow up planets. Run them into each other. Send Earth rocking away from orbit. Even if you're not a big Sanbox fan, this is still an incredible simulator and learning tool. Make Uranus explode or turn it into a black hole. Buy it.

Made Earth have the same mass as the sun and the sun have the same mass as Earth, then put the sun in orbit around Earth. I now have a solar system where Earth is the center of the universe.

I also put a tiny Earth in orbit around the sun. Because reasons.

A game where you screw around and cause planets to collide, change orbits, or make the sun go supernova. Another physics playground except this time its planets that are the tools rather than spawnable items like in Garry's Mod. Still. this is an interesting little game that can show just how even the smallest changes can have tremendous consequences.

Replayable depending upon your own interest in this sort of thing. For me, it's alright. :o
