Welcome to the Aperture Science Computer-Aided Enrichment Center.. Today, you will be testing alone. Just with me here to watch you. My name is Fenton, your leading A.I. Allow me to show you around.. You'll be testing with dozens of deadly elements! I hope you're as excited as I am, because we have a lot of testing to do. Go into the next room, pick up your portal device, and let's start the testing..
a bit of experimentation with opened chambers, likely to be the main chamber theme for the final mod.
Like!
but..i am? what..
the door at the end of the exit hallway is a fake because we don't need a real door there. the door at the beginning stays shut because the test chamber is being moved still.
