Space Quest I – The Sarien Encounter

Within the Earnon galaxy, Roger Wilco, a janitor aboard the scientific spaceship Arcada, awakens from an on-duty nap in his broom closet to find that the ship has been boarded and seized by the sinister Sariens. He soon learns that they have stolen a powerful experimental device called the Star Generator, which could cause untold disaster in their hands. Acquiring a keycard from a dead crew member's body, Roger flees the ship in an escape pod. Moments later, the Arcada self-destructs.

The pod crash-lands on the planet Kerona, a dry, barren wasteland. Roger defeats a spider-droid that the Sariens dispatched to eliminate him. In a cave system near his crash site, he is greeted by a mysterious figure, who offers help if he kills a monstrous creature called Orat. After Roger succeeds in the task, the figure supplies him with a skimmer craft to help him reach the town of Ulence Flats, where he can find a new ship.
