By 2059, the deterioration of the Earth's environment has become irreversible. In a few years, the Earth will be completely uninhabitable for any living species. Mankind must now plan its escape: an exodus into outer space. During the game players acquire and play cards trying to match the requirement for different mission cards. They use special powers and attempt to avoid events that might delay or sabotage their mission while using different strategies to outrace or hinder the opponents. Whenever a player has the right cards in front of him he can launch a mission and establish a base on the planet or satellite shown on the mission card. At the end of the game every base on a planet gives victory points as stated on the relative mission card. Different values are used if a player has a majority of bases on a planet. Bases on the moon give bonus points for every base established while bases on satellites are worth a fixed number of points.
