Uncover Diverse New Biomes

From towering underwater cliffs to lush coral fields, this aquatic alien world is brimming with vibrant and breathtaking biomes, each teeming with diverse ecosystems and unique creatures. But something isn’t right. The world is out of balance. What happened here? What happened to you? And more importantly, where are you?

Study Mysterious Lifeforms

Uncover a rich world full of mysterious lifeforms, from the smallest fish to the largest Leviathans. Scan creatures to learn more about them. Use your Biosampler to take samples for study. As you learn more about this world, evolve your genetics to adapt your body for survival.
