View FMV Sequences:

middle pciture where the Flak Jacket is located.

Getting Through the Subway:
Go to the opposite end of the subway after it explodes. Use the flashlight on the left of the tracks to
find the C-4. Get the C-4, then go to the right hand side. Look up to see the upper level. Press
Triangle to climb onto the red crate. Press Triangle to keep climbing up through the debris until the
top is reached. This is the only way to exit the lower level.

Museum Gates:
Find the card keys to get through the gates in the museum. Check all the guards and people that are
killed; they usually carry card keys. For the gate in the Rocket Room, shoot the control panel on the
third level that keeps sparking while your character is standing on the elevator to reach to that level.
The man with the card key is up there.

Grenade launcher in level 1:
Go out the window in the bar into the back alley. Look up and to see two fire escapes. Climb onto
the dumpster and get onto the fire escape opposite the bar first, then jump up to the pipes and go
hand over hand to the other fire escape. Be careful, because two terrorists will run out to shoot half
way across the pipe. After taking care of them, drop down onto the fire escape and open the box for
the grenade launcher. This makes the grenade thrower in the subway section much easier to handle.
