*Note: If you go to the elevator the extra guy in PA will ALWAYS spot you trying to go in giving you added problems. If you want to do that, you can, but this strat doesn't give directions for that.
End the cinema when Carrington says 'Excellent Joanna.' The elevator door now closes at 40s. Anyway, go forward, wait the .8 -1.5s for the crossbow to deploy, then turn left and shoot the guy. Right strafe to the guy by the alarm, and shoot him. Turn around, and shoot the guy walking into the cave (with his back to you). Then go into the cave, press start, and get out the drugspy. TT :10 - :12
Direct the drugspy to the waitress. If there is a/both guard(s) by her then take them out first, then take her out. If there was 'nobody/one guard that you took out' by her then go get your spy and uniform. You don't have to take the guards out if they're farther away because when they see you they do the 'surprised to see you' act, which gives you time. *Note: You don't have to kill any of the guards if you don't mind that they may possibly do some damage to you. Anyway, unarm yourself and put on the uniform while going back to the base entrance.
The extra guard opens the door at around :35 to :36, so if your under you'll have to open it. If you're over the door will be open, and if you're at about the same time be careful opening it so that you both don't open it which ends up closing it (*Confused?: You'll see what I'm talking about when that happens.)
Go into the elevator to your left. The girl should say 'Good Afternoon.' (If you're really early, go ahead and get the girl to say ' Ok. You know the way from here.') Stand back, get out your spy, and when the door opens put the spy in the path of the door, so it won't close.
*Note: Don't put it at the edges or else you'll waste about 5 seconds when you get back in and pick it up.
Get the suitcase and punch out the guy who would tell security about you. Then get back on the elevator and equip your suitcase. TT: when the elevator door opens: 1:06 - 1:10. Go to the locked door, press 'B' which tells you it's locked, then the girl should let you through after that. OBJECTIVE 1:COMPLETE.
Run and go down the stairs past the guy (which would be straight). Put the suitcase on the mover thingie (by pressing 'Z'). OBJECTIVE 2: COMPLETE. TT: around 1:25. Then run through the metal detector, past the green 'you shouldn't've come here girl' guy, and into the next set of hallways. You should be on disarm. Follow this hallway around the corner, then to the right, where you will take the guard's Dragon. Go up the stairs and press 'B' on the computer. OBJECTIVE 3:COMPLETE. Get out your dragon. TT: never looked.
Run like crazy back to the metal detector, ignoring all guards. There is a door to the right of it. Go through it. Follow this passage into a big, blue floored room with a guy here. Take him out. Now turn around and throw a proxy dragon. Go through the next hallway to where there's a guy with an elevator behind him. (There should've been a Dragon that you picked up at the corner.) Shoot him, and activate the elevator (for some reason I always forget to do that). Now for the only part of the level that you should ever die (and it might happen quite often). Shoot the guy by the door. You now have to ways to do the next part:
1. Throw a proxy dragon into the second room. When the fire clears stand back and take out the mine on the door.
2. Go to the furthest right corner of the first room. Shoot the mine on the door. Hopefully no guards will get in your way.
Either way the glass to the right of the door is broken. Get the dragon in the middle of the room if you don't have a dragon already. Go over to the broken glass, double crouch, and go into the room. Whip out your Dragon, turn around and throw it at an angle so it ends up in the middle of that room. (Uncrouch) Turn around again and in the right corner of the room is a switch with a cover. Press 'B' so the cover moves, then press 'B' again so the switch is pressed. Go to the safe of the middle of the room and get the flight plans. (Reminds me of GoldenEye [Bunker 00A & Surface 00A]) OBJECTIVE 4: COMPLETE. The proxy dragon should've gone off by now, so go back to the elevator. TT: Somewhere around 2:30.
If you remembered to call it before you got the plans, it should be waiting for you. If not, call it and wait for it. When you get to the bottom, close the elevator, turn around, and it should stop 1/3 of the way up. You are closer to the plane (without all the hassle). Go to the plane to COMPLETE OBJECTIVE 5. TT: If you were like me and forgot to call the elevator before getting the plans you will get around 3:30 (I got 3:30 exactly), but if you did remember you will get around 3:10-3:20.
