Roger Wilco is one of the most important men on the starship Arcada: he is the janitor! Just when he was doing what he does best (dozing off in a closet), the shrill sound of an alarm penetrated the air. Arcada is attacked by the evil Sariens! Before Roger realizes what is going on, he discovers that he is the only survivor. The Sariens have killed the entire crew and stolen the valuable Star Generator. Roger's immediate task is to find a way to leave Arcada, which is about to explode in fifteen minutes. And then he'll have to show the Sariens why they should never mess with brave intergalactic janitors!

Space Quest: The Sarien Encounter is a humorous sci-fi adventure game made with Sierra's AGI engine. The gameplay is similar to that of King's Quest: the player navigates Roger around with arrow keys and interacts with the game world by typing commands. There are puzzles to solve and plenty of situations where the player will have to use his wit to save Roger from death.

In the Amiga version of the game, there was a color change from light purple to an orange color in some of the game's graphics. So for example, in the Amiga version the sky on the Planet Kerona is orange, instead of light purple like in most versions of the game, including the original DOS version, and the floor in the underground alien settlement is also orange instead of light purple. See the screen shot section for examples.
