Anno 2070 expansion, Deep Ocean, will be released on October 4, Ubisoft has announced.

Deep Ocean introduces a new faction called the Techs, whom are able to expand further into the deep ocean. By experimenting with a new energy source called the geothermal power plant, players will be able to build massive production facilities below the sea with the aim to secure a limitless energy supply.

Energy transmitters will allow transporting energy between islands while the player can build the impressive new Tech Monument as well as new buildings and decorations.

The expansion also includes over 150 new quests, natural disasters and co-op features.
