About the game
Begin at the bottom of the food chain. Shape your body as you hunt, grow, and evolve across a vast ocean. Journey from sunlit shallows to the lightless abyss, surviving changing environments and deadly predators as you explore the deepest reaches of the sea.
Original Steam description
Morphsea: Abyssal Evolution is a single-player evolution game from a solo developer, built around freeform creature sculpting, survival, and deep-sea exploration. Explore, hunt, and evolve in a beautiful, procedurally generated underwater world.
Shape a Creature Like No Other
Freely shape your creature's body and equip it with parts that serve different functions. Eyes, mouths, fins, armor, spikes, and more don't just alter its appearance—they directly change its abilities and the way it survives.
There is no set path for evolution. Build for speed and agility, using keen senses to stay out of danger; or strengthen your offense and defense to become a predator that hunts other creatures. Shape a life form that is truly your own!
Hunt. Grow. Evolve.
Track down prey smaller than you, but beware of predators lurking just beyond your field of view. Feed to gain the nutrients you need to survive, then evolve into a larger, more formidable hunter and climb the food chain. But a larger body does not make you invincible. Your speed, attack strategy, resilience, and surroundings all shape the outcome of an encounter. Sometimes the best way to survive is not to fight, but to flee.
Explore the Ocean's Deepest Reaches
Explore a procedurally generated ocean, discovering the distinct landscapes and life found in each layer as you descend from the shallows into the abyss. As you go deeper, light fades, pressure mounts, and ecosystems transform around you. Creatures lurking in the abyss bring new threats, and a body built to dominate the shallows may be all but helpless in the depths.
To dive deeper, you must keep evolving.
