You are Annabelle. You don't remember where you came from, where you are nor what you are doing here... You are told to go down the hallway and enter a door. You are told to pick up the Aperature Science Handheld Portal Device and then to procede into the door infront of you. You go through a couple of regular test chambers, then you are told you are to be testing a new experimental and highly unstable world portal, and you go through a test chamber and testing the world portal. then proceding to the next test chamber, you are told that the flux capacitor that is running the world portals is malfunctining and to be carefull... and as your going through the world portal the flux capacitor breaks down and you are sent forward into time, into the Aperature Science Steam Center. Your job is to find a world portal in this "new" world, and start the generator to get it up and running
