Space Quest 1: Roger Wilco in the Sarien Encounter

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.
