Let's take you to the year 2070, where Global warming has liquefied the Arctic ice cap, which has increased the global ocean Level so that the shores are flooded. Because of that, many old cities have disappeared under the sea. Much of what was once uplands has been turned into chains of new isles. The settling and exploiting of these new boundaries are given to a select group of people who supervise mobile ocean-going bases known as Arks. With Ann0 2070- a well-regarded series of strategic city builders go rushing headlong into the future. The Game future the Game's futuristic vibe is apparent from the main menu screen, but the sci-fi fun goes far beyond the superficial. It's a one-two punch of Game addictiveness. The joy of watching your city grow!

The DLC packs are also available in the Game that players can purchase for reasonable rates. The Game has three factions:

• Eden Initiative (Ecos): Ecos are environmental and construct sustainable cities but are weak and slow to grow.
• Global Trust (Tycoons): Tycoons are industrious and develop fast but have difficulties with pollution and diminishing resources.
• S.A.A.T. (Techs): Tech is a support section available to the further two, and they help research the latest and most effective technologies. They are only open later in the Game when 10,000 credits are donated to their causality.

The gameplay includes "World Events"; special assignments presented only for a bit of time, letting all players band together and finish the projects i.e.

• First event: Neo Skullz Pirates
• Second event: Project Eden
• Third event: Global Distrust
• Fourth event: The Nordamark Conflict
• Fifth event: The Secret of the Ebashi Trench
