Approach the light... Enter the world that is outside Aperture... Free yourself... You are [SUBJECT NAME HERE] from [SUBJECT HOME-TOWN HERE]. After volunteering to take part in the Aperture Science Hand-held Portal Device tests, you notice something strange. In your head, something tells you that boxes shouldn't be orange, portal-guns shouldn't be red and security cameras shouldn't have blue eyes. Continuing anyway, a seemingly friendly robot called GLaDOS starts to guide you through the tests... As you finish however, in a attempt to get rid of you, she tries to kill you. Not succeeding however, you escape into the bowels of the Enrichment Centre. In a final stand-off against you and GLaDOS you defeat her and get dragged off unconscious by a "Party Associate". As you fall down through a old, unused vent, you land down in an different chamber. Can you escape?
Place this in Steam\steamapps\[username]\portal\portal\cfg. When in game, open the developers console, and type exec trailerslowmo Now, if you press the TAB key in-game, everything (apart from sound) slows down. Press TAB again to come out of slow-mo. Thanks, -HLCRAZY
