Play Space Quest: Chapter I – The Sarien Encounter Online – MS-DOS Game

Game Overview

Space Quest: Chapter I – The Sarien Encounter is a classic sci-fi adventure game that blends humor, puzzles, and peril in the tradition of Sierra’s early AGI-engine titles. You play as Roger Wilco, a hapless janitor aboard the starship Arcada, who becomes the sole survivor after the villainous Sariens attack, slaughter the crew, and steal the valuable Star Generator. With the ship set to self-destruct in 15 minutes, Roger must escape—and eventually confront the Sariens—proving that even an unassuming cleaner can become an unlikely hero.

Built on the same engine as King’s Quest, the game uses a text-parser interface, requiring players to type commands to interact with the environment while navigating with arrow keys. Its charm lies in its witty writing, creative deaths, and challenging puzzles, all hallmarks of the Space Quest series. Released in 1986, it helped define the sci-fi adventure genre, offering a lighthearted yet engaging experience that remains nostalgic for retro gaming fans.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
