Imagine Earth - Galaxies is an expansive DLC for Xbox One that enhances the base game with the introduction of entire galaxies, each featuring up to 20 unique planets available for colonization. Players can engage in either a free endless mode, allowing for limitless exploration and development, or opt for a competitive mode where they can challenge AI corporations. This variety provides a dynamic gameplay experience tailored to different play styles.

Central to the gameplay is the Space Station, which acts as the headquarters for managing planetary colonies and conducting interplanetary research. Players can unlock various extensions for city centers, enhancing their colonies' capabilities. Additionally, the new Orbital Space Lift facilitates the swift and cost-free transport of resources between the space station and colonies, streamlining gameplay and fostering efficient resource management.
