Directive 8020 starts aboard the spaceship Cassiopeia, where you join a group of scientists venturing to the exoplanet Tau Ceti f. Tasked with setting up the next intergalactic colony, all these scientists are meant to do is take a look at the new planet and figure out how safe it is for the colonists following their ship. I'll save you the suspense: it's not very safe.
Before you can even get situated, an alien lifeform finds its way inside the ship, and from then on you're tasked with keeping the scientists on board away from harm, aka the shapeshifting alien lifeform that seems to have an infinite amount of teeth, eyes, and flesh.
