World Record Time= 00:44----My Time= 00:48
Watch the cinema scene until just before the jumpcraft appears, then stop it. Immediately jump off the helipad to the left and turn around, while you are falling open the door and pause. Select the ECM Mine and quickly open the next door ignoring all guards. Run to the left and down the ramp to the comms hub, toss your first mine (don't miss, even though you have 3). Now turn around while moving backward, and go through the grated door. Now face the right side of the stairwell (the side with the door) and press up against the railing of the stairs while left-strafing really fast. If done correctly, you will ride the rail and go clear over the glass barrier. Immediately after you clear the glass barrier, start strafing back towards the stairs, you should go right in between the 2 levels and be almost right beside the door. Quickly open the door and if you have a weapon out go to unarmed. Head to the left into Cassandra's office and punch her out. Quickly strafe back out of the room as fast as you can and get in the elevator on your right (should be open) while closing it. Now switch to ECM Mine again and wait until you get to the bottom. Get out while the door is opening and make a u-turn and right-strafe to the door on the right, ignoring the guard(s). Open the door and as fast as you can without missing toss the next ECM mine on the comms hub. (It helps if you move up against the left wall, so that if you are shot it will not effect your aim as much as normal). Get back out of this room while switching to the CMP150. Strafe really fast across the lobby to the other door and go in. Try to ignore the guards in the lobby if possible, only shoot at them if they are blocking your path. Run in this room and to the right, open the secret wall/door and go into the elevator. Try to be fast and dodge their shots, because if one guard gets you, you're in trouble. It will knock you back then the other 3 will join in usually resulting in your death. If you want you can try to injure them without stopping, so it will give you a much easier path. Now your done.
