[8.5]. Mission 5 - Air Force One: Antiterrorism (2)

Locate and retrieve equipment: After the cut-scene, you'll be Joanna. Head through the next door, past the two guards, and keep pushing forward through a few more doors. You'll reach an area with one guard and a big red grate on the floor to your right. Use the Action Button to enter the grate. Downstairs, go through four more doors until you hit the kitchen. Keep going through the kitchen into the next room where you'll find a Hover Bike. Pass that and go through the next door. In this room, walk up to the guard, punch him out, and grab the card key he drops. Now, press the Red Button near where the guard was, then head back to the room with the Hover Bike. Find and press the Red Button located in the middle of the two doors, and then make your way back into the kitchen.

Locate President: Once you're back in the kitchen, look for a Red Button near the back of the room. Press it, and a small elevator will descend. Hop in and ride it to the top. Exit the elevator and go through the fancy door directly in front of you. You'll see some stairs; head up them. At the top, turn right, then right again. Go into the door right behind the guard to find the President and wrap up this objective.

Get President to escape capsule: Now, your main priority is protecting the President. Make your way back towards the red grate that leads to the plane's basement. After going through a few doors, you'll eventually reach the escape capsule. Phew, objective two complete!

Detach UFO from Air Force One: Time for the grand finale! Head back to the room with the stairs that led up to the President. Go through the fancy door marked with an "Exit" sign. Turn left and toss a Timed Mine into the UFO's docking door. Get clear quickly, and if you survive the blast, you'll have completed the mission!
