Creatura

Creatura is a simulation game about designing and managing enclosed ecosystems. You build customizable aquariums and terrariums, cultivate plants and animals, and balance environmental conditions to sustain them. You can follow evolution from single-cell organisms sharing water with algae to complex animals in lush gardens, or create a vivarium of your own design in the open-ended sandbox mode.

Build and manage ecosystems

Shape the ground and water level, and customize each vivarium’s stand, rims, lid, colors and form. Use decorations and consumables to adjust pH, temperature and humidity, and grow plants to generate oxygen. The game simulates these environments as you care for their inhabitants.

You can speed up time by as much as 1000x to watch plants and animals evolve over seconds. There are no fail conditions in the relaxing, educational vivarium-building mode, and challenging educational scenarios are also available alongside an extensive tutorial.

Breed and discover species

Use artificial selection to grow plants from billions of possible combinations, or breed animals through natural selection as they adapt to their environments. You can raise specimens until they develop rare variations, then keep, sell or trade them. Selling plant cuttings lets you buy decorations and consumables, while researching plants and animals unlocks advanced DNA-editing methods.

Discover and name possible plant and animal species, then add them to the global almanac as part of your evolutionary research. The almanac tracks species yet to be discovered, and rare parts and decorations can be unlocked for your vivariums.

Genetics and customization

An authentic DNA editor and the GCAT system let you edit organisms’ genes and apply genetic engineering. The game covers genomes, codons and gene sequencing, and explains how techniques such as CRISPR and GMO work. You can also use or create texture packs through Steam Workshop.
