Moon 2049 is a lunar space station simulator. You have the chance to explore the moon surface, including craters, basins, seas, mountains, bays and valleys. Maybe, you have already seen them in astronomy books or through a telescope, but now you can explore every corner on your own.
Also, you can assume the exciting role of an astronaut working on researches and living in the Moon base near Copernicus crater.
