The Tundra is a region in Anno 2205. Access to it is given to the player after acquiring the Tundra Downloadable Content. The Expansion costs 2.99.
The Tundra region comprises a single sector called Vanha Plains, a big continental map filled up by vast rocky marshes crossed by fjords and snowy mountains. Occasionally, a small snowstorm will occur, but a few minutes later, disperses. A command aircraft is used in this sector given the lack of navigable waters.
The Sector project is to drain the contaminated swamps and fix/destroy the 2-century old Eden initiative Vaults, as seen in the game's predecessor Anno 2070.
