Meet Guide

In your vision in X-16 you recalled Guide who knows every route in the Zone.
== Walkthrough ==
Guide can be located in Cordon, in the [ ruined house]. He agrees to help you find Doctor, but first you have to get his map from the Tricky stash back. You can refuse the quest, skipping it entirely and losing the rewards, and he will still give you the info.
== Notes ==
* If you're aiming for the main achievements (S.T.A.L.K.E.R. and New Game), don't refuse to help him. The transition you get as a reward is also convenient.
== Bugs ==
* Guide might not spawn if you haven't fully listened for the audio note on Ghost's PDA you picked up in X-16.
