• Shaping the diplomatic landscape by upgrading traits, changing diplomatic relationships, and leveraging the benefits of your allies, all with political capital.
• Unlocking a dynamic set of Diplomatic Traits while activating different combinations in response to the changing world.
• Playing as one of four new factions, including the Al Falah, a group of nomad explorers descended from wealthy and resilient Middle Eastern states.
• Investing in multiple Affinities to unlock hybrid Affinity units and upgrades for the first time.
• Collecting and combining alien relics via a new Artifact System that unlocks powerful benefits.
• Exploring one of two new biomes, Primordial world, an untamed biome rife with volcanic activity and indicative of a chaotic landscape still forming in the new world.

Rising Tide will be priced at $29.99 and more info can be found on the official website.
