Events in AquaNox take the gamer to the second half of the 27th century. Humanity left the land and ended up in the underwater kingdom. The reason for this is the resources that were sorely lacking. Because of the sea cities, the water level rose, and the inhabitants of the seas died out. Thanks to scientists, the restoration of fauna began. The developments of the professors were able to restore animals, but with them came long-extinct entities. The experiments did not do without the participation of people who mutated into ruthless creatures. The main problem at the bottom of the ocean were the Biont ships, which devour biological material.
