Blue Portal, Orange Portal

Portal, released by Valve in 2007 as part of The Orange Box, follows Chell, a silent test subject in the Aperture Science Enrichment Center. Her Aperture Science Handheld Portal Device creates a blue and an orange portal, linking any two suitable surfaces.

Puzzles rely on physics: momentum carries through portals, so falling into one launches Chell out of the other at speed. Long fall boots protect her from fall damage. Throughout, the AI GLaDOS, voiced by Ellen McLain, guides and taunts her, promising cake. Hidden scrawled walls warn that the cake is a lie, a phrase that became a meme.

Players must say goodbye to the Weighted Companion Cube, with hearts on its sides. GLaDOS sings Still Alive, written by Jonathan Coulton, over the credits. Portal grew from Narbacular Drop, a game by DigiPen students whom Valve hired.
