(2) Aggressive solution: Getting out of the ambush Deus Ex: HR Guide
Last update: 11 May 2016
Don't waste time on using Eliza Cassan's computer, as getting noticed by the security cameras shouldn't be too much of a problem for you. Get out of room 404 and head back to the main room on level 6. Take place by one of the pillars and start shooting at the three guards standing beside each other (screen above), without allowing them to split up.
After a successful takedown I'd suggest retreating to the previous corridor thanks to which lower the danger of getting flanked. Wait for more enemies to appear and start gradually eliminating them #1. Also look out for the enemies using EMP grenades #2. If you don't have the EMP Shielding, you have to retreat each time it falls near you.
Make sure that you eliminated all the enemies on the current level. Use the chance and check out their bodies #1, finding, inter alia, ammunition and a precious EMP grenade. Now you have to assume that some guards might have stayed on the balconies on the upper level 7 #2. Carefully use the stairs or shoot them from the current floor. In both cases you should consider using heavy weapons and staying behind cover.

Now you can focus on choosing one of the available evacuation routes, which will eventually allow you to reach level 3 or 4 and therefore get out of the ambush. The first option implies using the server room passage. The proper corridor can be found on the 6th floor, in the southern part of the main room (screen above).
Head towards the server room and shortly you will come across a door with a level 4 electronic lock #1. Luckily you don't have to play the hacking game here, as you can pretty much use the code gained from the palmtop (8825). Choose the stairs leading onto level 5. After reaching it, examine the area of the desk to find, inter alia, a software and unsecured computer terminal #2.
Take a look around the server room for a destructible wall #1, possible to destroy only with the Punch Through Walls augmentations. Use the ladder to reach level 3. Here you can find a fragile part of wall as well and it's best to blow through it at once, as there should be guards standing beside it. Therefore, there's a high chance they might be stunned #2 as a result.
Reward: 2400 EXP.
The second option implies reaching the lobby. It's the only possible solution if you don't have Punch Through Walls, though you can choose between two passages. The first is in the eastern part of the level 6 main hall #1 and the second by the balconies on level 7 #2.
A few moments later you should reach the lobby, which depending on the battles you might have had before can be either empty or occupied by two guards (screen above). If the enemies are still alive, you should of course hide behind some cover and shoot them out.
Your goal is to reach the elevators, though you should consider devoting some time on finding the new weapon upgrade. The most obvious solution is interacting with the left elevator #1. Go inside and wait until you're transported to the lobby on the third level #2.
Reward: 2400 EXP.
An alternative option is jumping into the right, inoperable elevator shaft #1, but in such situation you would need to have the Icarus Landing System augmentation. After landing enter the ventilation shaft #2 which will eventually lead you to a room on the fourth level of the hotel.
Reward: 2700 EXP.
Notice! The description of further actions can be found in Step 3 (Reaching the staircase at the back of the studio).
