Instructions
Throughout this level the guards will try and arrest Ethan. Once they tell him to stop and surrender, Ethan has a few seconds to hide before he is definitely arrested. You can avoid being arrested by shooting the guards with the dartgun, or by running out of their view (hiding behind a ventilation duct for instance). All the guards Ethan has darted wake up after a few moments, but they won't notice you while they're drowsy.
If Ethan is taken in a searchlight, it starts an alarm and brings the attention of all visible guards to him. They will try to arrest him if they are near.
Stun the first guard near the entry to the level and take his magnetic card so you can open the doors on this section of the roof. After running around the corner, opening the door and getting some more ammo in the small barrack, return to the first guard house. Climb on the guard's barrack to reach the second level. Turn the switch on the control panel to deactivate the electric floor, then access the second panel to shut down the lights on the helicopter landing pad. Back down on the first level (climb down close to the second panel), go around the block to reach another passage to another part of the second level, where you can find the bag Candice has left for you. In this bag you find a technician's outfit, infra-red vision goggles, an electronic device (Electro-Magnetic Scrambler), and a laser deflecting Item. Get everything out of the bag and put on the disguise. Further along you will find an internal passage to level three.
The Maintenance outfit helps Ethan to be allowed in the second section of the roof, near the helicopter landing pad. Taking the stairs on the left you go down to the lower levels and finds a control panel from which you can turn the lights back on. Now run back up and set the Electro Magnetic Scrambler device (from his inventory) on the panel near the landing pad. This will disable the electronic systems of the helicopter and keep it grounded for the escape later.
Back down to the lower levels. Shoot a guard with the dartgun and take his card for access to the next section through the door on the bottom level.
The door opens to the next section through a short corridor. Shoot another guard for his access card and go looking for a way to the top. The guards will be aggressive again despite his outfit since this is a maximum security area. Find some crates that will allow you to climb to the second level, but watch out: if you try to jump off the crate over the barriers, you will take damage from an invisible laser barrier. First put on the infra-red vision goggles to see the lazers, then use the laser deflector prism (from your inventory) to open a safe access to the second level.
On the second level the door to the passage for the third floor is protected by a digital code. Ethan has to set the Spy Camera on the crates next to the door (climb up, then attach it), and go away to wait for some one to do the code while the cameras records it. Going around the corner and waiting for a little while is all it takes. When that is done, get the camera and can access the third level.
On top of the third level you must avoid the last guards (watch out, one is right around the corner!) and enter the maintenance room where Candice awaits you.
