  3. murtaugh says:

    nicely done. I linked to it from my site.


  4. hfilby says:

    Wow! Thank you both for the kind comments.

  5. Matthew says:

    Nice, but still no answers. And who’s bunnygirl?

  6. hfilby says:

    Wow! Murtaugh posted a comment on my blog?

  7. Tim says:

    Im confused. The walkthrough says to go onto the roof to get the wheel by using the screwdriver… when i go there… THERE IS NO WHEEL TO BE FOUND…. what am i missing? help me out…

  8. hfilby says:

    Hi Tim,

    On the roof, if you go as far left as you can go, there should be a wheel on the wall under the roof where it makes a “vee”. I’ll post a picture above. Cheers! – H

  9. Tim says:

    Damn…. im a bloody idiot….. i didnt know that you could go further left than the ladder… i feel pretty dumb right now..

  10. Owned!!1 says:

    lol wheres the stone key(ancient room)

  11. Gunther says:

    Actually you forget one secret (yes there are 22 secrets).
    – Go back to 1,0,4 (ancient location) and take the charged coil out of the machine.
    – Go back to 0,0,1 (the lab), go left 4 times, up the stairs to the 1st floor, go right and you see another machine, place the coil in the socket and turn the small lever that is on the arm and it shall rise, revealing the 22th secret. I don’t know what to do with it I put in the ‘secret’ machine but it said ‘0/-1 secrets’ and nothing had changed in the ‘secret room’
    And maybe a silly question, but can the lock on the turbine be opened in the secret room?

  12. Human says:

    How do you leave notes, since you can make them? Can you?

  13. Human says:

    Also, you can go left at ‘Portal 001,’ but it ust shows a half-opened door, and you can’t reach it because of the iron grate. What is it for and how do you pass it. Also, someone said that if you press 398, it will take you around, but it doesn’t work! What is it for and what relation does it possible have with the potential ‘SM5?’

  14. Human says:

    Also, there is a secret in the lucky room (728)! On the window on top, there is a blue dot, which you can put into the machine!

  15. Gunther says:

    To human the secret in 728 is already listed in the walkthrough and no i don’t think the barrier between the machine and half opened door can be opened. I think this is the front door of the lab and that Marek or whatever he calls came in saw the machine and that the machine transported him to the roof with all entries to his lab closed off. anyway they say about the start off the game in one of the camara’s in the secret room

  16. Me says:

  28. hfilby says:

    Hi lulu,

    The coordinates for the ancient room are in the PRINTOUT you pick up after your conversation with M at the computer. To view the printout, click on your notes, and then click the first entry labelled “coordinates of known…”

  29. Chris says:

    Handy walkthrough to nip through the game as a refresher before #6 :) Thanks for this!

  30. Sandy says:

    what is the code for room: oh no – you’re on your own now!…

    i am not getting it…

    pls help

    • Adisa says:

      it’s 2011, but i hope i still help. :p

      in the top left of the wall you’ll find number combination (myself is 594) enter it to the portal.

      *spoiler* i found no change at the room at all. i gave up and decide to pull the “exit no return” lever. :p

      pretty pointless, but still exciting..

    • hfilby says:

      Hint: There is a clue in the last note you picked up.

    I really disagree! I am amazed that this really did happen in todays world. I was happy in the fact I was sat down. The Boss’ are coming to terms about things in future I need to keep an eye on what happens .

  33. Anonymous says:

    I really disagree! cannot believe that this is going on in modern day times. I was relieved I am not jogging. The Directors have wondered what will happen to this. I will need to know the evolving issues and going forth.
