Civilization IV - Planetfall Mod v13

Earth, 2060. A small group of colonists leaves the ravages of Earth for a distant planet orbiting Alpha Centauri's primary star. Their ship, the United Nations Starship Unity, carries them on their journey to a new world and a new hope for humankind. Along the way a reactor malfunction damages the Unity, precipitating a crisis among the ship's seven most powerful leaders. As they enter the Alpha Centauri system, the crew splits into seven distinct factions, divided not by nationality, but by ideology, and their vision for the new world. After the ship breaks apart, the seven leaders guide their chosen crew down to the surface of Planet, seeking their destiny beneath an alien sky.
