Part iv: Disused Military Depot

Head forward, and around the corner after the starting point. There will be a guard beside the first red crate. Kill him to get his gun. Continue on, and head left through these gates, not bothering to turn around and kill the guards chasing you.

Through the gates, head straight forward, until you come to a 'T' intersection. Head left, to this shed at the end. Step to the side, and open the door. Pick off the guard straight ahead, and another will appear. Make noise to draw out the guards behind objects.

Once the shed is clear of guards, crouch ('R' and bottom 'C'), and creep behind the right mainframe. At the top corner of the room, is a drone gun, (center of red circle). Just peek out far enough to catch a glimpse of the gun's edge. If you creep out much further, it will begin fire, and you must retreat behind until it ceases fire.

Step back, and blast the screen, because you need to destroy it, along with...

Be careful when exiting the shed, guards will be waiting. Shoot the nearby ones, and duck behind the blue train car visible here.

Head straight all the way, until the second last shed on your right.

Of course, there are guards who need to be killed inside the shed. You can collect Proximity mines, even a Rocket Launcher here. Spread the proximity mines over the boxes on the floor. You shouldn't need to use more than 4 mines.

Head to the exit, maybe placing a Proximity mine on the door, to clear out any guards waiting for you.

Head straight out the door, shooting only those in your path. The straight path goes around a fenced in area, and leads you to this train station, where you go inside.

Head up the stairs, and grab the blueprints from the safe there. Objective "D" completed.

Objective "E": Completed

Of course there are guards in the train, but you can watch Bond take care of them in the cinema scene.
