The alarm has been given, and there are dataDyne shock troops ready for you throughout the building. Exit via the foyer is impossible due to the number of ground troops present. The transport will collect you and Dr. Caroll from the helipad.
I don't have to remind you to protect Dr. Caroll at all costs, Joanna. Cassandra and dataDyne are going to be throwing all the obstacles they can in your path to prevent you from getting Dr. Caroll out. Good luck.
Objective One: Access the foyer elevator. [A,SA,PA]
Fight your way around the foyer until you can get access to one of the lifts that will take you and Dr. Caroll to the upper floors of the building.
Objective Two: Reactivate Elevator. [PA]
We traced an order to shut down the only accessible elevator to a PC on the lowest floor of offices. You have to find that PC and change the order to get this elevator going again.
Objective Three: Destroy dataDyneHovercopter . [SA, PA]
There is a dataDyne security Hovercopter circling the building which outguns your jumpship and will shoot you out of the sky. Terminate it with extreme prejudice, since it will be trying to do the same to you.
Objective Four: Defeat Cassandra's Bodyguards. [A, SA, PA]
We suspect that Cassandra has deployed her bodyguards to block the route to the helipad. It is almost certain that you'll be unable to avoid them, so expect serious resistance when you encounter them.
Objective Five: Return to Helipad for Evacuation. [A, SA, PA]
Get to the helipad where your jumpship will be waiting. And don't forget Dr. Caroll.
Falcon 2 (scope): Equipped by Joanna from the start.
Falcon 2: Guards may equip one if disarmed.
DY357 Magnum: If you reach the first guard in the lobby hiding behind a desk, and kill him, without being spotted, he willl drop a Magnum.
CMP-150: All male guards carry this.
Shotgun: All female guards carry this.
Dragon: Found in the cheese area. The second weapons cache.
Rocket Launcher: Found on the level of Cassandra's office.
Grenade: Found in Cassandra's office, on her desk. Mainly used for getting to the Cheese/Dragon area. The first weapons cache.
Night Vision: Equipped by Joanna from the start. Needed for the beginning of the level when the lights are out, and also at the end while in the Internal Comms Hub room.
(Cassandra's) office key card: A guard on the upper floors carries this, but he only appears if Joanna reaches the elevator without being shot. It is used (unsurprisingly) to get into her office, but it also unlocks the security room on the bottom floor.
This is the same cheese as in DataDyne Central: Defection. The way in through the Internal Comms Hub room does not work this time, the only way to get in is through Cassandra's office.
To get into her office, you need to get to the first elevator without taking damage. Once you get to the higher floors there should be a guard just around the corner. Kill him and he'll drop a keycard to Cassandra's office, which will have a grenade on the table. Use it on the wall shown in the picture to get to the cheese. There is also a Dragon in this room.
Good Enough for Clint - To earn this crown, you must kill eight enemies with headshots, using the hidden DY357 Magnum, on Agent difficulty. The Magnum, which can be found by killing the first five guards you encounter without being seen (See Walkthrough), must be acquired before tackling this crown. This can be somewhat easy to do, depeding on your skill level. You will have just enough ammo to complete this, but if you miss, there are a few oppurtunities avalible to earn double headshot kills, although it is hard to pull off.
The key card mentioned above also opens the security room, the room containing the External Comms Hub from dataDyne Defection. Inside, you will find Mr. Blonde and two female guards, apparently being stored there until the cutscene. You can shoot them, but they can't die. There is also a couple of ammo boxes containing rockets, unless you are on Agent difficulty, in which case they're found on the roof. Presumably it was an oversight by Rare making the key card open this door too.
On the floor where Joanna must switch elevators, there are several bodyguards which must be killed to complete the "Defeat Cassandra's Bodyguards" objective on Special and Perfect Agent. On Agent difficulty, they're still there, but you can complete the objective without killing them.
It is possible to destroy Dr. Caroll without failing the mission. Once at the helipad, if Joanna still has a rocket left, she can lock on to Dr. Caroll with the secondary mode and fire it while running and activating the cutscene. The rocket will follow him during the cutscene before finally exploding and leaving Joanna to carry nothing onto the dropship. The warning that Dr. Caroll is under attack will still show up.
You can block Dr. Caroll from going up the elevators with you. This makes it easier to keep Dr. Caroll alive if one is having trouble with that.
