The Terrestrial Planets when you start the game.

The first four planets of our solar system, plus the moon.

Introduction[edit | edit source]

These five worlds are the five that can be played for free. The player begins their journey on Mars, after which they slowly unlock each other planet.

Venus, and Earth and can be unlocked by purchasing an all-access pass, but can't be bought individually or as a set. Generally though, they are unlocked for free by completing the other worlds in this set.

Worlds in sets other than the Terrestrial Planets have to be purchased before they can be played.
