You've already battled across the galaxy in
Beyond Earth, but coming this Fall, Firaxis and 2K will be expanding the latest Civilization title by releasing the Rising Tide Expansion Pack. Not only will it include the option to build floating settlements and explore the vast seas and oceans for the first time, but Rising Tide introduces four new factions.
"New aquatic gameplay will explore the oceans for colonization by dramatically extending the play space, while an overhauled diplomacy system will provide players with additional layers of dynamic choices and options to shape the diplomatic landscape while engaging with the AI and one another."
Since the start of the Civilization series, water has only been used to travel to and from various lands. Rising Tide expands the playable area, allowing you to explore the oceans. The diplomatic mechanics are also receiving some love in this expansion pack, adding dynamic elements when dealing with AI and other human players.
Sid Meier's Civilization: Beyond Earth - Rising Earth will be available for PC in Fall 2015 for $29.99. Expect to see more about the expansion pack during E3 2015.
