Intro. Background: At the end of the twentieth century, scientists discovered a vast sea beneath the icy radiation surface of Europa, the conditions in which are conducive to the emergence and maintenance of life. In 2022, the first space team arrived on Europa and discovered that there is life on the moon in the form of aggressive underwater fauna. Researchers faced other problems: dangerous radiation emanating from Jupiter and the colossal ice pressure of the European ocean. Earth colonists managed to build several inhabited outposts, where a new way of life developed for decades. over the years, European society became more and more cut off from the Earth. Fifty years ago, contact was completely lost and supply ships stopped coming. The key to surviving in the new society is underwater transport and travel: finding new places to live, protecting the locals from being attacked by creatures, and establishing supply routes between stations.
