If you play as one of the Shipwreck Survivors, you explore the planet Artemia using Place cards. Using your Survival cards, your aim is to avoid being hunted down by the Creature until help arrives.

If you play as the Creature, your aim is to hunt down the Shipwreck Survivors from space and assimilate them into the planet’s biomass. Using your Hunt cards and Artemia’s various flora and fauna, you repeatedly attack the Shipwreck Survivors in order to wear down their will and inescapably bind them to the planet.
