(1) Reaching room 404 Deus Ex: HR Guide
Last update: 11 May 2016
You begin the mission on the building's roof and your first mission will be reaching the room where Eliza Cassan is supposed to be. Hear out the short conversation with Pritchard and leave the helipad.
Before you take care of reaching the office, it would be good to reach the fenced area on the building's roof. You can achieve it in three ways. The hardest is to interact with the electronic lock on the gate #1, having level 4 security. If you don't want to play hacker, you can examine the area on the right and jump onto the boxes #2. Unfortunately jumping over the fence is possible only if you have the Jump Enhancement.
The last variant implies entering the building and afterwards reaching the western storage room. Afterward you could use Punch Through Walls to create yourself a passage through the less tough wall fragment #1. The prize for reaching the fenced area is mainly the precious weapon upgrade #2.
Regardless of whether you have reached the fenced area or ignored the possibility, you have to enter the building and follow the only possible corridor #1, finding an Ebook on your way. Afterwards go west and turn south. Go down the stairs #2 onto the lower, seventh level.
Open the door leading to the large room of the broadcast centre (screen above). For now you won't come across any enemies in the area, so it's worth to take a look around. It's especially important if you're planning on sneaking through later on, as you will be able to quickly leave the area, without having to worry about collecting items on your way.
I'd suggest starting off by exploring the small room in the south, on the seventh floor #1. Inside, inter alia, you will find an unprotected computer terminal #2, drawer and Ebook.
Go out of the room and head into the conference room a bit further to the north #1. Inside you will come across a palmtop (login: pkane, password: staxx). East from here #2 there's a small storage room, through the only interesting thing there is a drawer.
Continue exploring the seventh floor, finding more drawers and reaching an evacuation route, inaccessible for the time being #1. Keep such places in mind, as soon they will act as possible escape routes and/or new spots to examine. There are three such passages in the area in total (one on the seventh and two on the sixth floor). After exploring the seventh floor, choose any staircase leading onto the lower, sixth level #2.
Start the exploration from examining the southern evacuation route, coming across a palmtop #1 with a code - 8825 - into the server room. The next palmtop can be found in the north part of the big room #2, it contains passwords to three employee computers.
It's also worth to thoroughly explore the main part of the sixth floor #1. Especially look for drawers, as one of them #2 contains a free Praxis Kit. Apart from that you can also find an Ebook and interact with five computer terminals in total. Most of them are unprotected, through in two cases you will have to do some hacking or make use the recently obtained passwords.
After exploring the area, head to the north-west corridor leading to room 404 #1. On your way it's of course worth to stop by the rooms you come across. The first one has an entrance from the north side #2. Inside you will find a drawer and computer terminal with level 1 security. Also notice the ventilation shaft in the wall, which you will be able to make use of later on.
Return to the corridor and head south. The next room is 402 #1. Inside there's a drawer and an unprotected computer terminal. Return to the corridor and this time head to room 403 #2. There you can find a drawer and another terminal with no security.
Temporarily ignore your target (room 404) and head to the southmost room #1. Apart from the drawer found there, you should take a look at the computer terminal, the gun lying on the desk #2 and the ventilation shaft entrance. Just like with the northern room, it soon will be one of the possible escape routes.
Eventually head to the room 404, marked by the game #1. A cutscene will start, during which you will speak with Eliza Cassan #2. However eventually it will turn out that you're not really talking with the real Eliza, but her hologram. Troubles only start here, as the mercenaries found inside the building will be informed of your presence.
