Securing the Convention Centre
Marchenko plans to attack London's Apex Centre during the Safe Harbour Convention. TF29 found out and tried to convince billionaire business mogul Nathaniel Brown to cancel the event—but he refused. Now it's up to me and the team to make sure everyone attending the convention stays safe.

M15: Securing the Convention Centre is the 15th main mission in Deus Ex: Mankind Divided, and the first one to take place in London. Adam Jensen flies with TF29 to the Apex Centre to try and stop Marchenko's, and therefore the Illuminati conspirators', plan.

Primary ObjectivesEdit

Meet Liam Slater in the C.S.O. Edit

In London, you will meet and briefly talk with Nathaniel Brown, who refuses to cancel the event regardless of what you say, so Jim Miller decides TF29 needs to do their own sweep and Brown agrees. He will then tell Adam to work with Tarvos Security to make sure everything is in order. You can explore the top area around the helipad if you want, but there is not much to find.  Make your way to the elevator and head down to meet with Liam Slater, the one in charge of convention security. Adam will contact Alex to keep her up to date, but Janus will respond and say the UN delegates are of the utmost importance as the Human Restoration Act cannot pass, to which Alex agrees. You will then reach the security level.

In the initial area there is not much to explore, but you will find a vent behind some vending machines that can lead you into the next area or the security room. It is heavily advised if you are doing stealth to go into the latter and shut off everything you can. Go talk to the guy behind the window where Adam starts to have a suspicion something is not right.  You can choose to outright attack them or decide to be more discreet (trick or back off result in the same thing, though the first will make the guard behind the window walk off). Adam will then notify Miller about his suspicions and Duncan MacReady points out similar thoughts as nobody from Tarvos Security on his end have contacted him yet. Miller then tells Adam to get to Liam Slater's office to see what is going on.

Get to Slater’s Office Edit

If you hacked the security terminal earlier, you will have to go back and turn off the 2 cameras that turned back on if you want to take out the guards in the front without alarms going off. As MacReady can not move any further into the building due to being locked out, Adam has to get to Slater’s office to override the security shutdown to let the rest of the team in.

Activate the Security Override Switch Edit

If you do some exploring in the area, you will confirm your suspicions when you find dead Tarvos Security guards and gold masks in some of the rooms, which will activate this part of the mission. Get to Slater’s office and you will find the code for the switch on the unlocked terminal. Once overridden, you will see Brown pop up on screen as he talks a bit in the reception hall before Adam notices the terrorists are slipping in through a back door near the catering area.

Find the Keycard to Catering Edit

Now get back to the elevator and head to the reception hall. Miller will tell Adam to take out all the reception hall guards quietly, and find the keycard to access the back area.

If you do not care to take out all the guards, you can find the keycard 2 ways: on the guard using the restroom or, with the klipsringer aug, travel in the vents that connect the restrooms to jump up into an area of the ducts where you hear 2 guards talking and move around until you are near a damaged vent opening and you will see a keycard. As soon as you get the keycard, MacReady will be out of commission for a little while due to tripwires in a stairwell.

Quietly Neutralize All the Guards (secondary) Edit

Taking out the guards is optional, but if you do not take them all out an alarm will be triggered later, so if you are going for the Foxiest of the Hounds achievement, take them all out quietly. A few tips on taking them out without causing an alarm or panic:

  • Mind the cameras and guests watching.  As long as the guests do not see you do a takedown, or the cameras do not spot a body, you will be fine.
  • Some reason, guests do not freak out if a guard suddenly goes limp and falls over from a tranquilizer, so use that to your advantage.
  • Naturally, other guards will not react so well if they spot a body and will sound the alarm and attack.
  • Do not drag bodies if no other guard is in the vicinity in the unrestricted areas, as guests will then decide you are acting suspicious and panic.
  • Perform takedowns from cover, so the guards will be dragged out of sight instantly. Make sure the guests don't see you doing this, unless you are taking them out when you are invisible.

Investigate the Catering Area Edit

Make your way to the secured door and head through and you will find out you can not get a hold of Miller, but MacReady can read you.  Continue through towards the marker.  If you did not grab Damocles’ Sword during G.A.R.M., this is the area to grab it if you want to use it in the final fight.  It will be in the room past the catering area (around the corner), in a box under a desk.  Enter the catering area and a cutscene will play out. Now you have a hard choice to make...


  • Supposedly, if the alarms are set off before you enter the hallway of the catering area, Marchenko will shorten the time until he detonates the bombs, making it more difficult to get the achievement Spokes in Two Wheels.
  • The guard with the keycard may not be in the restroom (appears to have been changed in a patch).
