You've crash-landed on a deserted planet. Your rocket broke apart on impact, scattering its parts across hills, chasms and deep underground. The only way home is to find every last one and rebuild the rocket.

BUILD YOUR OWN MACHINE

Snap wheels, frames, motors, springs, suction cups, propellers and cargo boxes together on a grid to build a vehicle that's entirely your own. Shape and setup decide everything: whether it climbs the hill, clears the chasm or flips over on the first bend. The physics are real, so you can try out every idea on the spot.

EXPLORE THE PLANET

The world is one big, seamless place. You decide where to go: across the surface, up into the sky or down into cramped caves that call for a completely different machine. Along the way you'll discover abandoned bases and push on from there.

HAUL YOUR CARGO HOME

Every part you find exists only once, and nothing makes its own way back. Whatever you find, you have to load up and bring home. Hauling the big rocket parts is a fresh puzzle every time.

UNCOVER WHAT HAPPENED

Ship's logs lie next to the parts. Bit by bit, they reveal what went wrong on the flight and who built the abandoned bases on the planet.
