The Anno 2070 game is allowing the players many missions, the first single player campaign called Shadows of the past. There many locked campaigns also, the second campaign, Chapter 2 called C.O.R.E. and the third campaign, Chapter 3 called In the Eye of the Storm.
In the above two screenshots are based on DX11 rendering, mind you that the game is DX9 compatible as well.
The Anno 2070 official system requirements are the following: Intel Dual Core 2 GHz processor, 2 gigabytes RAM memory, a 512 MB video card that supports Pixel Shader 3.0. Anno 2070 will require at least Windows XP SP3.
But if you want eye-cany like shown above, a modern graphics card is very much so recommended.
By the way these are all crops from 1920x1200 screenshots. Overall you'll likely agree with me that the graphics are a good improvement over Anno 1404 (if you played that game).
