Rover Builder

Rover Builder is a 3D engineering simulator where you build and customize rovers to complete levels. Each level sets challenges and puzzles across difficult terrain and hostile environments. Get your rover to the green completion pad, and earn a three-star rating by finishing as quickly as possible.

Build your rovers

An unrestricted building mode lets you make vehicles ranging from buggies to trucks, cranes and rocket-powered rovers. You can combine available parts into intricate designs and working systems, including steering, hydraulics, suspension and propulsion.

Take on missions

The game includes over 40 developer-made levels, with challenges such as crossing increasingly difficult terrain, retrieving and returning objects, and destroying obstacles and enemies. Each mission has its own challenges. You can also build a convoy of rovers to complete a mission efficiently, or visit the community garage to see how other players tackled the levels.

Create and share levels

A level editor provides the tools used to make the official missions, along with dozens of tools, features and options for creating levels and missions for others to play. The community has made hundreds of additional levels.
