Firaxis and 2K Games have released the gameplay walkthrough for Civilization: Beyond Earth's forthcoming expansion Rising Tide, which was shown behind closed doors to E3 attendees earlier this month, for your viewing pleasure.
As you'd expect, the focus is very much on water in the expansion, with new artifacts added on land and at sea. These can then be used immediately or fused to enhance their effects.
Additional biomes have also been introduced, while the game's diplomatic options have been overhauled. Players have the option to construct floating settlements, while four new factions are also included.
Civilization: Beyond Earth Rising Tide is due for release this autumn for PC and Mac.
