#[NTRO]#{Intro}#
################

I am writing this guide to assist anyone who might get stuck throughout the 
single player portion of Portal 2. I am attempting to make this guide as 
spoiler-free as possible, and because of that, I'm keeping the instructions to 
a bare minimum. Without exploring the chambers, or at least taking a look at 
them before trying them, a lot of these steps won't make sense. If for whatever 
reason you're just starting the game for the first time, and you intend to play
through it with a guide, I highly recommend giving it a shot without one. 
All of the answers are quite simple with just a little bit of critical 
thinking, and solving the test chambers for the first time on your own quickly 
becomes a very rewarding experience!


[Using the Guide][UTG]
If you glance at the instructions for some of the test chambers, you'll notice
the steps (new / next steps marked with the preceding "-") are pretty vague.
In my opinion, a huge part of this game is really absorbing the environment, 
and placing yourself in this world of science. I don't want to fill up the
guides pages by describing the rooms in great detail, before giving you any
direction, and the more detailed I get, the more I risk spoiling something 
neat. The guide is broken up into sections, between the games loading screens.
Keep in mind, that each step is written assuming you've already walked 20 
feet ahead of you to the obvious next room, or have already navigated the 
linear walkway between sections. Each step also assumes that you are 
following the guides example for at least that puzzle. That being said,
have fun!
