(1) Reaching the Convention Center Deus Ex: HR Guide
Last update: 11 May 2016
Get out of Jensen's apartment and head towards the left elevator #1, the one which will take you to the ground floor. If during the first visit in Detroit you reached the police station by persuading Wayne Haas (the Investigating The Suicide Terroris main mission), you will meet him here #2. Haas will be furious, as because of the investigation he has lost his job.
You can end the conversation with Haas in two way. If you intend to help him, choose Absolve #1. The main hero will offer Haas a job at Sarif Industries. If you don't intend to help Sarif, choose the Crush option. However be careful, as you will make him angry enough to attack you #2. It's best to quickly stun him or kill in melee combat.
Regardless of whether you have met with Haas or not, get out of the Chiron building. The Convention Center is in the south-west part of the map, nearby the recently visited LIMB clinic to be precise. As a reminder, you can get there in two ways, namely by choosing the passage by the Chiron building #1, or the indirect path running beside the police station #2 and through the rail station.
Inside the Convention Center, it's worth to listen to the conversation with Pritchard #1. He will tell you that Sandoval has checked out of the building and will offer you a side quest - Acquaintances Forgotten. Apart from that I would also recommend paying the LIMB clinic a visit #2, as there are two new Praxis Kits available.
Head south, getting off the main path after reaching the tunnel #1. A bit later you should reach the Convention Center entrance. Head inside, going forward and then turning right. Find the double door #2 leading to the proper objective.
