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.

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.

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...

In a blog post outlining the game's development roadmap for 2016, Universe Sandbox 2 developer Giant Army has announced it is introducing virtual reality support to the solar system simulator.

The developer mentions that basic support is currently working for its internal builds, and it is aiming to support the HTC Vive and Oculus Rift. However, "there’s still a lot of work to do in fine-tuning the experience of reaching out, grabbing the Moon, then hurling it toward Earth."

Colliding planets is just one of the cosmic-scale possibilities in Universe Sandbox 2, a game that simulates Newtownian physics, climates, black holes and dark matter to create one of the most detailed representations of the solar system you can find on a PC. The game is treated as something of a toy box - in addition to smashing planets together, you can terraform them, hurl asteroids at them, or build new planets out of basic materials like hydrogen and iron.

Universe Sandbox 2 is currently on Steam Early Access, though no date has been set for when a VR-supporting build will become available. Additionally, the developer has no firm release date for the full game, but anticipates continuing work in Early Access for the better part of 2016.
