This one will be difficult to beat, you'll need to try and avoid taking damage. First, leave the explosives and run up to the end of the corridor. Shoot the first guard in the head, then wait for others to come and do the same. Try to get head shots as they'll go down in one shot. Run around the corner, knock out the guard and get the second Falcon 2 from inside the barrel. Go towards the elevator and if any guards see you, make sure you get rid of them otherwise they'll keep running after you.

Go up the elevator, and make your way across the bridge, taking out any guards along the way. Before getting in the second elevator, try to get all the guard's attention up on the balcony so that they all get in the elevator. Plant a proxy Dragon on the ground in front of the elevator to blast them all. If they don't all get in, you'll need to stand up against the elevator door as you go up and then blast them quickly. Use a proxy Dragon to blow open the wall, then make your way up the right. Shoot any guards along the way and grab a SuperDragon.

Switch to grenade launch and open the door on the right as you go down the ramp, then quickly destroy the gun turret on the wall before it sees you. Take out the Data Uplink and use it on the computer at the far end of the room and wait for the virus to be sent. Once all the doors go crazy, go back up to the top of the ramp and go into the room that was normally locked. Blast the guards in there and destroy the computer for objective 1.

Rush down to the bottom of the corridor to where the two doors leading into the showers are. Face the door on the left and fire a few rounds at it to get the guard's attention inside. As soon as he opens the door blast him and rush in. Go to the showers, shoot the lab technician before he runs, then switch on the X-Ray Scan so you can quickly find which locker has the lab disguise. Once you find it, switch to Unarmed then activate the disguise for objective 3. Rush out of the elevators and make your way back to the ruptured wall.

Continue left of the opening and keep going until you reach the containment labs. Go into the one on the right, then go up to the first switch on the left and activate it. Turn around to face the tube and activate the X-Ray Scan. Stay there until the scanner is finished looking at the alien and displays Objective 2 Completed.

Leave the lab and head back down the long corridor. Go into one of the doors on the left (the one that isn't locked) and head down the large room. Knock out the two guards so that they don't come after you later. Once the guard at the end of the room opens the lab door for you, knock him and the lab technician out, then enter the glassed-off area and knock out the technician to get the access key card. Take out the SuperDragon and head back out, switch to grenade launcher and fire at the main door to the lab.

Two bio-lab technicians will come out and get caught in the blast, keep firing to blast the guards that also come running in. Quickly rush out of the large room back into the corridor, and rush to the other locked door. Fly down the room, taking out any guards with grenades, and enter the lab at the end of room. You'll only have a few seconds to get to Elvis, so blast all three guards and the lab technician with grenades. The last one to fall will drop a key card, grab it and rush towards the glassed-off lab to end the mission. This cheat might take a while to get, I managed to get 7:22 minutes, well below the limit, so it's not impossible.
