I am at the LAX parking garage. I have killed the guard in the booth and the police and dog. I believe I am supposed to enter the door next to the guard shack, but it is locked. Any suggestions? This is on PS2. Thanks

Are you sure you killed the guard that was in the guard booth? That's the first of 10 terrorists throughout the level, and you can't get through that door until he's dead, not just unconscious. To identify which ones are terrorists, use thermal vision. They'll show up a bright orange because of the smallpox vaccine they took increasing their body temperature. These fools must be killed, not just KO'd, in order for you to finish the mission.

If that guard's body is still bright orange, put a bullet in his head and the door will open.

PS - I've only played the Xbox version, but I have to assume that door's locked for the same reason on the PS2.

Not to mention that killing anyone else is forbidden... Try doing that first part without bothering the patrolling guard and his dog - it's pretty easy, no really!

It's a fun little challenge to try and pick off the terrorists without tipping off any civilians in this mission. It really enhances the being sneaky aspect. This first one the trickiest part for me was popping the terrorist and getting his body through the door to hide him before the dog picks up your scent and finds you.

What a great level, even though it goes against the "killing is a last resort" mandate.
