Protecting the Future

M17: Protecting the Future is the 17th main mission in Deus Ex: Mankind Divided, and one of the last missions (depending if you did M16: Stopping Marchenko first). Adam Jensen must save Nathaniel Brown and the UN delegates if he wants to stop the Illuminati conspirators' plans, but at the cost of hundreds of others' lives.

Achievements

Find and Protect the Delegates
If you did the The Heist and got the Orchid cure, you can use it right after the cutscene to save Jim Miller or, if you do not think you will make it to the delegates in time, save it for them. However, if you move quickly enough and do this one before dealing with Viktor Marchenko (or use the secret door that connects the two areas), you can stop the delegates from taking a sip and therefore save them without needing the antidote.

Despite what Marchenko says, he will not detonate right away. If you did not set off any alarms before entering the catering area, you will have 10 minutes to save the delegates and stop Marchenko before he sets off the bombs. There are 2 ways to the delegates: If you did this mission last, then it will cut to the ending and you can see how your choices play out in your conversation with Alex and on the news.
 * 1) Head to the delegates directly. Having a lot of biocells, Icarus Landing, Leg Silencers, and maxed out Glass-Shield Cloaking will greatly help if you decide to use this approach as the area will have a lot of guards and a couple turrets. You can either ghost by them (remember to use the leg silencers if you walk/run) or use the vents to get close enough. The key thing is to move quickly as you can. Do NOT call the elevator to the floor if you are trying to ghost as it will attract the nearby guards’ attention. Instead, go through the nearby door with your keycard and fall down to the elevator below. If you gave Alex the evidence from M7: The Rucker Extraction, she will contact you here to give you a code. Take the elevator to the VIP rooms and run to the door at the end to save the delegates and use the code to enter (2202). Once in, a cutscene plays out and, if you were quick enough, Jensen will stop the delegates from taking a sip. Otherwise, if you have the cure, you can save them with that. If you were too slow, they will be dead.
 * 2) Go confront Marchenko in the exhibition hall first, bypassing the guards in the first option. After the fight starts (or ends if you use his killswitch) head up the stairs where the turret is. There is a switch underneath the table (near the mines) that will open a back entrance to the delegates. Follow the arrows to the executive lounge and enter. If you were fast enough, you will be able to save them. You can then head back through the hidden door (it is part of the green monitors behind the mounted camera) to deal with Marchenko if you did not finish him off first.
