Crawl out the vents, and out of the stall. You don't need to kill the guards in the bathroom.

Head down the stairs, and turn hard left, through the single door.

Kill this guard and take his keycard.

Head left, through the green hallway, killing guards you come across. You'll come to these doors, open the left one, and again kill the guards you see.

After your complete circle of the area, clear the guards out of this room.

Fire off your KF7 to get these guys in the hallway, and finish them off.

After killing the guards, go inside their room and press "B" at this computer to activate the security door, then hurry around before it closes.

Take out the guards in the locker room, then turn around and be prepared for guards to come from the right, and finish them off as they come through the door.

After killing them, open this door, and toss a mine far down the hall, step back, and quickly press A+B to detonate the mine, and get rid of the guards.

Check the rooms on either side of the hall for Dr. Doak, the double Agent. This time, he was in the left room, but he can also be in the right room. Just see all the "B" locations on the map at the top of this page.

Head back to the hall way, turning left of course, and go through these sliding doors.

Turn left, and fire your KF7 to get the guard at the end to open the door, and finish him off.

Head up the stairs, kill the guards in your way, and check each lab for Dr. Doak (if you haven't already found him yet.) Clear out the guards before they can react and hit you with a shot.

Head down the hallway, disposing of any other guards, and you'll reach the bottling room door. Select the door decoder from your inventory. Press "Z" to use it, and open the door.

Make sure 006 sees you, and runs to you, so he's well away from the tanks.

Plant 3 of your mines on the first 3 tanks of this row, on the inside, so it'll blow up the tank in front of it too.

Then, throw the last mine between the last two tanks, and press A+B when it's in between the both of them, and still in the air. This will destroy those tanks, combined with the rest that have already been mined, completing the objective.

Use your watch detonator to destroy the rest of the tanks. By this time, the objective of talking with 006 has been completed, and you can leave the level. To be sure of this, watch for the "OBJECTIVE C: COMPLETED" message. Most players won't notice it, but if you've planted the mines in a normal time, then the objective will have been completed.
