Sid Meier's Civilization: Beyond Earth — Rising Tide — an addition to the turn-based strategy in a futuristic setting. 4 new leaders and factions have been added to the game. The espionage system has changed significantly and will now provide more opportunities for taking energy, science and technology from other factions, as well as for re-recruiting units. Artifacts have also been added — remnants of goods from the old Earth and alien gadgets from other worlds.
The add-on requires the original version of Sid Meier's Civilization: Beyond Earth.
