Confronting Eliza Cassan

Chapter 11 - Truth and Lies Eliza Cassan wanted to tell Jensen everything she knew about the kidnappings, but "someone" wouldn't let her. That someone turned out to be Fedorova, another of the black op mercenaries. Jensen killed Fedorova in a tense yet silent fight, enabling Eliza to admit some truths. First: the world's most famous newscaster is actually an AI. Second: David Sarif knows more than he's told. And third: Jensen hasn't seen the last of anti-augmentation extremists...

M1 - Confronting Eliza Cassan is a mission in Deus Ex: Human Revolution.

Primary objectives
Go to room 404 After leaving Tai Yong Medical, you will be dropped off at the Picus Communications building to find Eliza Cassan. When you leave the Helipad to the door that leads into the building, you can enter the enclosure to the right by hacking the level 4 lock. You can also jump over the fence surrounding the enclosure utilizing nearby crates or, having entered the building, break into the enclosure through a weakened wall. The enclosure contains a few supplies and an ammo capacity mod.

Continue inside the building and Jensen will notice that there's no one in the building and that there's abandoned items everywhere. You figure out that the fire alarm was pulled and everyone has left. You are welcome to explore and take everything you want. There is a Praxis Kit in one of the desk drawers in the main open office. When you are done, move to the objective and watch the cutscene where Eliza will talk to you.

Room 404 is on level 6.

Escape the ambush by reaching a lower floor
After the cutscene is over, you will be tasked with going to lower levels and finding where Eliza is held. The main open office area is now filled with Belltower soldiers looking for you.You can clear everyone out. There are also vents accessible from an office and a conference room near room 404. These vents will let you out on the second level of the main office. As there are fewer guards on the second level, this route is somewhat easier. After escaping the main office, you come to a lobby area patrolled by two guards. Take them out or hide from them. At the far end of the lobby is an elevator and an open elevator shaft. If you have the Icarus Landing System, you can drop down the shaft. Otherwise, take the elevator. Either way leads you to the main newsroom.

Alternatively, the arrival of Belltower opens several firedoors, one of which leads to a two-level server farm. On the bottom of level of the farm is a weakened wall that can be used to get down to the newsroom. However, to get access to the newsroom, you must break through a second weakened wall and this may alert nearby guards.

The newsroom has an upper catwalk system and a main floor. Both are occupied by more guards and the main floor has a turret. Located near a set of stairs connecting the main floor and the catwalks is a security hub. You can hack this without worry of being seen and use it to either activate or turn off the turret. Note that if the turret is made to attack the guards, one of them may trigger the alarm system. The newsroom is worth looting as there are plenty of credits. A cubicle with boxes blocking the drawer contains a silencer mod. There is an Auto Unlock Device under the console behind the northeast staircase. Once you are done, continue down the stairs. There are two guards at the bottom of the stairs which can be taken out using the Quicksilver Reflex Booster augment. The hallways nearby are empty and the two nearest rooms contain loot. The third and final room is your destination

Get to and summon the funicular
The third room contains the funicular towards which Pritchard has been directing you. The room also contains two guards, a turret, and a camera. In the hallway immediately outside of the room, there is a vending machine. Moving the vending machine reveals a ventilation shaft that exits near a computer, which is the security hub controlling the turret in the room. The guards can see you while hacking the computer, so either block their view or time your hack attempt correctly.

Take out the guards or sneak to avoid them. Summon the funicular by pressing the button near its entrance. Pritchard will inform you that the funicular is on its way and that an alarm has been sounded. You must wait a while for the funicular to arrive and during that time, additional guards will appear. Beyond simply fighting it out, you can: Pritchard will let you know when the funicular is halfway there and when it has finally arrived. When it has arrived, enter it and start the ride down. The button to start the funicular is on the right-hand wall as you board.
 * Make use of the turret. Use the security hub to hack the turret and let it take care of the additional guards.
 * Block the doorways. It is possible to use the vending machines in the area to prevent any additional guards from entering the room.
 * Hide. There is the ventilation shaft mentioned above, another passageway running under the stairs leading up to the funicular, and a third passageway between one of the room's entryways and funicular itself. You can use these to conceal yourself until the funicular arrives.

Get inside room 802-11
The funicular lets you out into a room with a camera and several crates. The exit to the room leads to a long hallway and is guarded by laser sensors. There is a security panel next to the exit. Hacking it will allow you to turn off the lasers, but to do this, you should position the crates in the room so that the camera cannot see you. Alternatively, once you near the exit, two guards will come down the hallway towards you. They will enter the room, talk for a moment, then one will leave while the other will commence a patrol. You can take down one or both guards and position their bodies near the laser sensors to deactive them (though this may trigger the camera). Last, there is a weakened wall to the far left side of the exit. Breaking through this will grant access to a ventilation shaft that bypasses the sensors.

Once through, proceed through another newsroom. There are two guards on a catwalk up above and several guards on the main floor below. It is not difficult to avoid them all or to take them all out. After the newsroom, proceed down a flight of stairs (watch for the two mines on the wall) to a lower level. Another guard will be patrolling the hallway. Take him out or avoid him by going through the offices to his right. Those offices also contain the security computer for the hallway's cameras. Also, at the bottom of the stairs is a weakened wall, behind which is a hidden area containing loot and a ventilation shaft that can help you bypass the guard. Along the hallway are locked offices with additional loot, so it may be worth taking out the guard in order to do some exploring.

At the end of this area, there are a set of double doors with a level three lock. If you can't or do not want to hack this lock, there is a work room to the right of the doors that is patrolled by two guards. A camera at the far end can be disabled via a security hub on the left side of the work room. This room can be worth exploring as it contains yet more evidence of how Picus is fabricating the news. Either way, once done, the next marker leads to an encounter with Yelena Fedorova.

Defeat the mercenary leader
Entering the room where you will fight Federova triggers a cut scene in which you discover the true nature of Eliza Cassan. She also reveals that the next target is Isaias Sandoval.

Go to the chopper and extract
After defeating Federova, go to the landing pad and leave.

Fedorova Tactics

 * Fedorova is the second boss encounter in Deus Ex: Human Revolution.
 * The fight takes place in a large octagonal room with four power generators, conductive coolant on the ground, and several large panels.
 * Supplies are located throughout the edges of the room in lockers. Helpful items include:
 * Shotgun (and ammo)
 * Heavy rifle (and ammo)
 * Revolver (and ammo)
 * Machine pistol (and ammo)
 * Typhoon ammo
 * The game can be saved during the encounter.


 * Fedorova attacks with dual SMGs and by charging the player and using the Typhoon.
 * Between sets of three Typhoons Fedorova will activate cloak and circle the room.
 * When destroyed, the power generators will discharge electricity through the coolant dealing ~90 total damage over time to anyone touching the floor and stunning Fedorova.
 * Both the player and Fedorova, or a combination of both, can destroy a generator.
 * Jensen is immune to electricity if he has the EMP upgrade for Rhino Dermal Armor.
 * Fedorova can be tracked using Mark and Track, Smart Vision, the visual distortion of the cloaking field, her casting a shadow on the outer walls, or ripples in the coolant from footsteps.
 * Fedorova will parry any takedown attempt dealing damage to Jensen.


 * Fedorova is vulnerable to headshots as well as EMP, concussion, gas, and frag grenades.
 * Setting traps using UR-DED or proximity mines works well.
 * Fedorova can be stun-locked with the stun gun and enough ammo (~25 darts on Give me a Challenge)
 * Using the Typhoon Explosive System is effective but risky if Fedorova is not stunned since she has a Typhoon of her own.
 * One of the easiest ways to kill her is to stun-lock her with an EMP grenade, which enables the player to use the Typhoon safely (requiring 2 energy cells loaded + 2x Typhoon ammo if fully upgraded).
 * A (maybe even easier) way to kill her is to:
 * Sidestep her to avoid her first rush
 * Shoot rockets at her when she is still in front of the wall that use to be behind Jensen. She will be shocked for a time, a time equal to reload time of the rocket launcher.
 * Four rockets are necessary, after what half a dozen shots from an armor-piercing pistol will finish her.
 * The whole fight can last less than two minutes.
 * It's also possible (if you have the Leg Prosthesis enhancement for it) to jump onto the lockers and then shoot the power generators to ensure Fedorova comes to a quick end.
 * There is a pathing bug where Fedorova will become stuck in place running. However, it is unknown if it is possible to induce this.

Glitches

 * Not necessarily a glitch as such, but likely unintentional behaviour: Before summoning the funicular, if the appropriate augmentation is active, it is possible to effictively seal off the room by blocking the doorways with the turret, boxes and the vending machine. That way the enemies won't find a way into the room.
