G-Man keeps an omnipresent watch over your movements
throughout your adventure in and around City 17. His locations
are as follows.
1. Chapter 1: At the beginning. [Screenshot]
2. Chapter 2: On a monitor screen in Dr. Kleiner's lab after Barney
finishes at the terminal. [Screenshot]
3. Chapter 3: On the TV that the Vortigaunt is watching inside
the red train carriage. [Screenshot]
4. Chapter 4: Standing on the pier in front of Station 7 at the
beginning of the chapter. [Screenshot]
5. Chapter 4: Flickering on a giant monitor attached to the high-rise
building. It is very quick, but if you look carefully you can
see the skeletal form of G-Man on the screen. [Screenshot]
6. Chapter 6: On a small gantry near the second covered bridge.

7. Chapter 6: In the last part of the chapter you will come across
a pier next to a dam. Get onto the pier by driving up the ramp
in your speedboat and turn left by the big red warehouse. You
can see G-Man staring to the right at the bottom of the rest of
the pier. [Screenshot]
8. Walking into a train tunnel beyond the railcar blocking the
railroad. See the "Hidden G-Man" hint for a detailed
description. Note: This sighting is not in the official strategy
guide. [Screenshot]
9. Chapter 9: Looking through a window near a pair of double doors
on a monitor screen at the beginning. [Screenshot]
10. Chapter 11: On a TV at the ruined foyer at the tenement block
after you and Dog get separated. [Screenshot]
11. Chapter 14: At the end. [Screenshot]
12: Chapter 7: Highway 17. After you cross the beach with the
boat ramp, go inside the house where the two combine soldiers
are located. Use the binoculars to see new little Odessa (resistance
stronghold). The G-man will be talking to an allied soldier in
the loft of a farmhouse. Note: He is difficult to see, but you
can see his briefcase.
