About Primordialis
Primordialis is a physics-based roguelike fish builder. You create a creature from cells, then explore the primordial depths and fight other creatures to uncover the world’s secrets and find out what lies beyond. Your fish can attack with venomous tentacles, electrical shocks or exploding children.
Build your creature
Your body is made from cells, each with its own properties and functions. You can place and combine more than 60 cell types to create different designs, from a massive serpent that swallows other creatures whole to complex mechanisms and circuitry.
Survive the depths
In the main roguelike mode, you grow and evolve as you explore a harsh world and face a diverse ecosystem of handcrafted enemies. These enemies are built with the same creature creation system as your fish. You discover cell types, mutations and other tools to help you survive, and traverse five main biomes to find what lies at the end.
Sandbox mode
Sandbox mode lets you refine creature designs before a run, study enemy biology or build creatures at your own pace.
