Universe

In Megaton Rainfall, aside from Earth as primary location, the Universe as a whole is second to it. Leaving the Earth's atmosphere allows you to travel throughout the solar system, out into the galaxy through nebulas and star clusters, and eventually out into Deep Space where you can travel to new galaxies.

As far as is known, Earth is the only planet in the Universe that you can find with life. It is unknown if it is possible to discover the Intruder's home planet, although it is probably unlikely considering the massive size of the Universe, and that we are never explained from where the Intruders came. Planets and moons range in appearance, size, and composition. There are gaseous planets, rocky mountainous planets, and oceanic planets all with different atmospheres.
