Aqua split into a few political camps: the Capitalist Aquatory, the Atlantic Federation of Democrats, the Clan Union of the Oligarchs, and the Shogunate with its monarchy. The year is 2661 and the survivors live in sprawling underwater cities.

True, it is difficult to get there, because only wealthy people could afford it. People had no choice but to live at these stations in the ocean. All kinds of disasters, floods and nuclear winters began here. With the use of nuclear weapons, all living things disappeared and the planet turned into a dangerous wasteland. Now all countries are quarreling and waging wars over the remnants of resources that were the last on Earth. All was going well until the mineral reserves there, too, ran out. Many countries have built ore mining stations here.
