Hi, welcome to the Portal Wiki. Feel free to ask for help on the relevant talk page if you're unsure about anything, or join us on our IRC channel.
On another note, I've just played through the core section and the long fall down the tube, however I didn't spot Rattman as you claimed you did in your. I even slowed the game to 1/10th speed; would you be able to provide a screenshot of your finding so that we can verify your findings?
