Civilization: Beyond Earth is a turn-based strategy, 4X video game... A spiritual successor to Alpha Centauri, Beyond Earth shares much of that game's development team, as well as some concepts... The game's setting is unique to the Civilization series in that it takes place in the future, with mankind traveling through space and founding colonies on extraterrestrial planets after Earth becomes uninhabitable due to an undescribed disaster known as "the Great Mistake".
