The Earth in the latest Civilization game has been destabilized by a series of global events and is overall, not doing terribly great.
Sid Meier’s Civilization Beyond Earth will have players finding a home somewhere in the stars by colonizing a new planet. Players will select one of eight mission sponsors and assemble a spacecraft while also choosing your colonists and cargo that will directly affect your starting conditions on the planet.
Additionally there will also be a new orbital layer, allowing players to build and deploy units that can provide offensive, defensive and support capabilities from orbit.
You can find more over at the Civilization website.
