Looking through our Portal 2 Strategy Guide? In chapters 5, 6 and 7 are a few hidden areas where you’ll discover a few awesome things from Aperture Science’s past. All three of these are tied to Achievements and Trophies, and they also reveal things about how Aperture relates to the larger universe of Half-Life and the creation of GLaDOS.
WARNING: SPOILERS WITHIN!
Portrait of a Lady
Find this hidden room to snag the “Portrait of a Lady” Achievement or Trophy, and also get a little bit of extra story about the characters of Portal 2.
Chapter 6 has six doors that are marked “Vitrified.” They all used to be test chambers that were sealed off, and each one gives you a little bit of Cave Johnson wisdom when you hit the squawk box beside it. Listen to them all to learn a little more about what Aperture Science was up to, as well as snag the “Door Prize” Achievement or Trophy.
In Half-Life 2: Episode 2, near the end of the episode, the characters in that game discover a ship they describe as being “near-legendary.” It’s the Borealis, an Aperture Science ship that seems to have been missing for some time. In Chapter 6, you can discover where the ship is supposed to be, as well unlock the “Ship Overboard” Achievement or Trophy.
