Sid Meier's Civilization: Beyond Earth is a turn-based strategy game created by Sid Meier and Firaxis Games and released on October 24, 2014. Beyond Earth is not an expansion pack for Civilization V; it was released as a standalone game. It is said to be the spiritual successor to Sid Meier's Alpha Centauri. Lead designer David McDonogh has even said "For all the fans out there of Alpha Centauri, this is the game we have made for you." An expansion pack called Rising Tide was announced in May 2015, and was released on October 9, 2015.
