About Homebrew: Patent Unknown

Homebrew: Patent Unknown is a vehicle-building sandbox where you assemble and test land vehicles, aircraft, boats and more. You can combine ordinary parts with logic components to create machines such as autopilot vehicles, stabilizing systems, transforming vehicles and robotic arms.

Build and experiment

You can customize your creations with parts including engines, wheels, wings and weapons. The game models land vehicle physics, aerodynamics and water dynamics, including waves, so you can put your designs to the test.

Explore the world

The world contains multiple islands where you can test your vehicles. It has a dynamic day-and-night cycle and weather system, and is large enough for testing cars, boats, supersonic planes and other vehicle types.

Multiplayer

You can play online and battle with friends.
