It's the year 2442, and Earth is facing complete destruction. The sea level is irrevocably rising, and the vast depths of the ocean now lie above the former land areas. Inspired by Jules Verne's visions and equipped with the latest technology, a deep sea city — "New Eden" — is being built, with the main dome standing on a "White Smoker", a spring at the bottom of the sea from which hot water flows at up to 300 °C.

This current forms a basic supply for the inhabitants (represented in game by coins), and from there, the station is constantly being expanded and enlarged with useful modules from the last mega-factories on the coast of Mount Everest or from the black market in order to receive further resources, points, and lucrative advantages. Many of these well-intentioned actions can damage "New Eden", however. Will the station withstand this damage, or will it collapse in on itself? Only those who keep an eye on the balance between progress and destruction can collect points in the final scoring. Whoever has built the most points and thus the safest and most livable station wins "New Eden".
