Portal vs Space Quest: The Sarien Encounter
Side-by-side comparison of features, pricing, ratings, and alternatives.

Portal is a first-person puzzle game developed by Valve. Players take on the role of Chell, a test subject who awakens in the Aperture Science computer-aided enrichment center. Guided by the sadistic artificial intelligence system GLaDOS, Chell must navigate through increasingly challenging test chambers using the 'portal gun,' a device that can create two portals that allow for instant transportation between them. As Chell progresses through the game, she uncovers the dark secrets behind Aperture Science and must use her wits to escape the crumbling facility.
