(5) Peaceful solution: Get out of the Convention Center Deus Ex: HR Guide
Last update: 11 May 2016
The last part of your trip through the Convention Center will look a bit different depending on how you gained the information on Sandoval's hideout and it you have already fought against Taggart's bodyguards.
If you have talked with Taggart at the backstage, you will be able to leave the Convention Center building without being bothered by anyone. Return to the main corridor and turn right. After reaching the crossroad, choose the path leading right #1 and you will reach a staircase #2. Go down to the lowest level.
After using the stairs open the closest door and afterwards turn left #1. Afterwards keep following the linear corridor and soon you will reach the Convention Center exit #2.
If you have unnoticeably reached the backstage, things will get much difficult as you will need to avoid enemies and defence systems. You can act in two ways. If you don't mind taking risks, you can try to destroy the nearby wall (screen above), however you would need to have the Punch Through Walls augmentation and afterwards quickly run away, as your actions could alert the guards.
A much better idea is trying to reach the exit without destroying the wall. In order to do that, you would have to begin with hacking into the second computer terminal #1. It has level 4 security, but after gaining access into the system you could switch off the local security cameras #2.
Hacking into the computer luckily isn't absolutely necessary for success. Carefully return to the room with the guards #1. Pass behind their backs, closing in on the corridor with at least two guards. If you haven't switched off the security cameras, you will additionally need to avoid one of them. Wait for the right moment or use the Cloaking System augmentation and turn right twice #2.
If you have done everything according to plan, you should end up beside the staircase #1. Head down, but stop beside the place where two guards will be talking #2. Wait for them to finish their conversation.
Note that one of the guards is going up. You can avoid him by using camouflage, or get rid in melee combat #1. After a successful action keep moving on, but don't go to the very bottom. Instead, look around for a ventilation shaft entrance #2.
After going through the ventilation shaft, you should find yourself above the corridor #1 patrolled by at least one guard. Head south. Jump down only after finding yourself somewhere around the plate informing of an exit #2 and after the guard faces the other direction. Now you can easily reach the building exit.
