About this game

Smash planets together in a real-time physics simulator. Watch a Mars-sized world hit the young Earth, debris spread into a disk and a new moon form, and tides stretch and spin up worlds. Up to 4 million particles on your GPU. Record the raw simulation data and replay from any angle at any speed.
