Imagine there has been a catastrophic glacial melting due to global warming, and you are the president of the last group of survivors living on islands.

Sunken Islands is a city building game in which you are tasked to take humanity back to the course of growth and prosperity. However, you MUST heed your predecessor's mistake and find a perfect balance between prosperity and greenhouse gas emission. To do so, you must also carefully invest in both GreenTechs and environmentally friendly facilities. Otherwise the remaining glaciers will melt and completely eliminate humanity.
