Features Virtual creatures evolve on their own to adapt to an environment you create At Ecosystem's heart are evolving virtual lifeforms, who grow from synthetic DNA and live in a physically-si. The simulation actually determines the creatures in the game: their bodies, how they swim, and how they think and behave. All the creatures in the trailer evolved on their own in the game; none were hand-edited. Ecosystem isn't just a video game version of the laws of ecology with pre-made fish models.
