    You can also grab Wheatly on Test Chamber 2 when he pops out of the wall. http://www.youtube.com/watch?v=xnu0Noi0gf4&feature=related

    As response to this comment. Chell can’t be Cave Johnson and Caroline’s daughter. Here’s why: Since Caroline was in GLaDOS, that means Cave Johnson had to have died before Caroline. This is based on his request to put her in the computer, if he could not be. Caroline, to be in GLaDOS, had to also be dead by “Bring your daughter to work day.” Since GLaDOS released the neurotoxin on this day. Chell was someone’s daughter on “Bring your daughter to work day.” To bring your daughter to work, you need to be alive (not dead and in GLaDOS). It is determined that Chell was brought to “Bring your daughter to work day” by the potato experiment. Plus, “Bring you daughter to work day” was suggested as being many decades after the Cave Johnson reign, by the various dates in the game. He could not father a child young enough to make the potato experiment if he had been dead that long. She's adopted...

    I was thinking Cave and Caroline were Chell's grandparents.

    she is adopted by ratman or someone we dont know yet because if you get rid of the huge potato plant on bring your kid to work day you can see on Chells prodject it sais somthing look on youtube for "Portal 2 who or what is Chell." PS I DID NOT MAKE IT!

    Oh my god. Gamesradar, Make it 31. At the beginning of the level where you encounter the Companion cube, while holding it, notice that a panel moves near the right of the lift. Behind it, Atlas peers out, then closes it quickly.

  • mooney003 - September 4, 2011 2:32 p.m.

    It's not atlas. It's another core... Just like the one in Chapter 2; Chamber 2. It's a core... not Atlas...

    It's Wheatley. He's been stalking you the whole time since you started testing again, waiting to help you escape. You see him the first time you use the laser redirecting cube, then in this one, and other levels along the way.

    Another Easter egg that I didn't see on the list is in the same chamber that has the "conservation of matter" award the companion cube is playing the turret opera song. I thought it was something else at first, but if you look right at you can hear a "music box" version of it coming from the cube.

    @aegodbold it is said many times that chell is adopted. so it is very possible that when caroline knew she was going to become glados and had just had Chell she let another high up employee adopt her, wich explains the bring your daughter to work day scenario, and explains when glados sais repeatedly that Chells left her as a baby so it all fits together.

    Also, the Fact Core mentions Prometheus also. If you listen at 5:15 in the link, he says: "In Greek myth, Prometheus stole fire from the gods and gave it to human kind. The jewelry he kept for himself." Just another reference.

    So this is an old article, but I didn't discover it until recently (a sad fact indeed) Anyway, one cool little thing about the 7th rat man den that I was in a video, if you go into the den and into the little hallway (via the broken window or the fan grille) and then leave, if you attempt to go up there again, the panel leading to the den will be closed, as will the door in the little hallway. Not sure if someone already mentioned it, but in any case, it's interesting. GLaDOS is apparently a little more concerned about the dens than she lets on.

  • xItZoToMx - July 12, 2011 4:52 p.m.

    i dunno if this is on here already but after you go into a certain rat man den (cant remember which one sorry) the fat turret is in the elevator at the end of the chamber.

    And... lol yeah, I'm Italian and I didn't had to translate the final song xD Lucky Italian people like me <3

    Aperture Science is heavily implied to have caused the zombie apocalypse featured in Valve's Left 4 Dead series also known as the "Zombie Urban Environment test area". There is hidden area in Left 4 Dead 2 in which you and your teammates are welcomed into the Enrichment center and forced to complete a few tests with the promise of cake at the end. The video is here: http://www.youtube.com/watch?v=0mE94ocfx9k

    That's a community made map you tool. It's not canon to the Half Life/Portal universe or Left 4 Dead universe. There have been no aperture science references (except for still alive) in either of the left 4 dead games. Neither has there been a reference to Left 4 Dead in any of the half life or portal games. The Half Life/Portal Universe and Left 4 Dead universe are completely different universes. To repeat it has never been implied aperture caused it, it was only in that COMMUNITY made map as a joke.

    You missed one, in the scene where glados tells you this test needs explaining, and it explains at super fast speed, if you slow it down she quotes Moby Dick yet again

  • StephanieNikole89 - September 17, 2011 1:53 a.m.

    Dude that one is on this list. She only quotes moby dick once

  • apocalipstick - December 4, 2011 10:52 a.m.

    They mentioned that one, it was on like the first page

  • FrenzyClinic - June 17, 2011 9:58 p.m.

    You missed one. In your Turret Opera video, there's a Rattmann cameo, complete with companion cube. He runs by really fast, so spotting him might not be easy as you think it is. He appears around the 16 second mark.

  • StephanieNikole89 - September 17, 2011 1:51 a.m.

    It's not rat man, there is a you tube vid where they zoomed in, its just companion cube being sent through the shoot to be sent out of the lab after you, as shown in the end.
