Enjoy a physics sandbox with an unprecedented amount of freedom.

• Plan your build, spawn the objects you need, and put together whatever contraption you can think of — from cars and rockets, to catapults and out-of-this-world machines.
• Enjoy community-made custom modes. Solve an online murder as a detective in Trouble in Terrorist Town or take on the challenge of a shape-shifting game of Hide & Seek in Prop Hunt.
• Jump into the Steam Workshop for over 300,000 models, maps, and contraptions from the game’s ever-thriving community.
