Chapter 3, Test Chamber 11
Pop behind the bridge-emitting wall panel in this chamber for a fleeting glimpse of Wheatley as well as the Rat Man’s fourth den. Wondering why his murals are always so strange? According to the comic Portal 2: Lab Rat – which is where most of Doug Rattman’s sad story is told – he is a diagnosed schizophrenic who must go off his medication while hiding from GLaDOS. Thus, the crazy paintings, crazy messages and crazy infatuation / conversations with a Companion Cube he believes is sentient.
Chapter 3, Test Chamber 12
More fascinating background on Doug Rattman, whose fifth den is located above the ceiling of this test chamber: He didn’t just escape and hide from GLaDOS. He plotted to destroy GLaDOS, searching for the perfect test subject (guess who) and moving her to the top of the experiment list so that she would automatically be first to confront the homicidal computer. When he realized that Chell had been dragged back into the facility at the end of Portal 1, he attempted and failed to rescue her, but he did manage to place her in long-term stasis, thus setting up the events of Portal 2.
What happened to Doug Rattman while Chell slept? According to the comic, he was shot by sentry turrets, then slipped into unconsciousness. Surely he died in the 9,999,999 days since… unless he also entered hibernation.
Chapter 3, Test Chamber 16
Use the laser to destroy that grate you passed on your way into this chamber and you’ll be rewarded with far more than another Rat Man mural – beneath the floor of his sixth hideout is a quartet of singing turrets!
Precious, aren’t they? Foreshadowing, too.
Chapter 3, Test Chamber 17
There are two entrances to this hideout – through the broken window near the ceiling or through the open wall panels on the adjacent wall. Our video demonstrates using light bridges to reach the latter. What’s inside this final Rat Man den? On a regular play through, nothing but more murals, beans and mugs. By the way, have you read the writing on those mugs?
Anyway. Enter this room with developer commentary turned on and you’ll find a speech bubble. Hit it for more of the shrill modem audio we heard in Rat Man Den #3. This time, the noise decodes to tongue-in-cheek information cards on the Portal 2 alternate reality game created by Adam Foster.
Unlocks “Good Listener” Achievement / Trophy
While escaping from the test chambers with Wheatley, the always helpful GLaDOS will offer you an easier alternative exit. If you’re smart, you ignored her and ran in the opposite direction. If you’re curious or completionist, however, you took the bait… and, after a brief glimpse at the outside world (i.e., fake plants), received a lethal lungful of neurotoxin. Worth a shot!
Unlocks “No Hard Feelings” Achievement / Trophy
Save this lonely, discarded turret from the “redemption” conveyor belts and you’ll receive something much more interesting than the Achievement or Trophy – prophetic knowledge of the past, present and future. Once held, the Oracle Turret spouts cryptic sayings that hint at a surprisingly deep knowledge of Aperture’s history:
• “The answer lies beneath us.” A clue to the original 1950s-80s test spheres buried below the modern labs?
• “Her name is Caroline. Remember that.” Indeed. For anyone still unconvinced of Caroline’s true identity by end of game, this seals the deal.
• “Get mad!” “Don’t make lemonade!” Quotes from Cave Johnson, who did try to upload himself into a computer near the end of his life. Perhaps the turret holds a piece of Cave’s personality.
• “It won’t be enough.” Either a doomsday prediction of the future, or another memory of the past. Doug Rattman wasn’t convinced adding a morality core to GLaDOS would be enough to quell her violence.
• “That’s all I can say.” You tease!
Unlocks “Scanned Alone” Achievement / Trophy
So easy, and yet so easy to miss. After you’ve removed the working turret from the scanner, but before you’ve replaced it with a malfunctioning turret, stand in the machine yourself. Once the blue lasers have analyzed you, the Achievement / Trophy will pop up.
