You completed the debate with Allison Stanek.
There’s no special requirements for this Trophy/Achievement save for actually doing the mission itself. At the end of Mission 10 you’ll be given a choice between two different locations, helping Allison for Mission 11 or the bank heist for Mission 12. You can only do one of these on any given playthrough so make a save before attempting this mission and take Mission 11. At the end of the mission you’ll have a social debate with Allison Stanek and regardless of the choices you make, the Trophy/Achievement will be awarded upon its conclusion.
You Know What To Do.
Your first possible opportunity to get this is during Mission 11 (if you took that route) when you’re in the Church of Singularity (You can enter this place after the bank if you took that route instead). On the ground floor, head out to the back and into the courtyard where you will come across some basketball hoops. Grab one of the nearby basketballs and drop it into the net to score yourself another Trophy/Achievement.
Use the Ice Drill to bypass a large section of the GARM facility.
Make a save at the start of Mission 13 as there are numerous ways this can end up costing you your Foxiest of the Hounds Trophy/Achievement while attempting. At the beginning of the mission you will need to call either Miller or Alex, make sure Alex is your call as you’ll trigger an alarm later if you call Miller.
As you head through the area you’ll come across a large fan with a nearby breaker panel that can be smashed to the right and then activated to shut it down. You’ll now be able to access this vent here and can follow it through to a room with a control panel that requires a Biocell to start up. Duly oblige, activate the panel and press the “Rear” button on the left to trigger a cutscene where you’ll be shouted at for using the crane. Select the “Scold” dialogue choice here to be left alone and then press the “Left” (the north most button) twice followed by the “Forward” button to unlock the button just above the control panel. Hit this button to unlock the Core Driller Trophy/Achievement.
Spokes in Two Wheels
You managed to stop both the bombing & the Orchid poisoning. You're a living legend!
This won’t technically unlock until during your last cutscene in the game however you need to fufill the conditions while you’re in London. At the end of Mission 15 you will get a cutsene and then recieve both Missions 16 and 17 at the same time, both of which can be done in any order. To obtain the Trophy/Achievement you must do both of these Missions within 10 minutes, a feat that should be no problem if you’re following the Walkthrough in this guide.
He's Not Dead Jim
By using the Antidote, you saved the life of Jim Miller.
The conditions for getting this begin all the way back in Mission 12, when you’re in the bank for the heist. While you’re inside the bank you’ll have to hack the vault to access its contents. Make sure you pick up the “Orchid Neutralizing Enzyme” at all costs (and don’t forget the missable eBook while you’re at it) as you’ll need this for Mission 15. On this mission you’ll come across a critically poisoned Miller so make sure you speak to him again after your conversation with Marchenko and give him the antidote to get the Trophy/Achievement.
You used Marcheko's Kill Switch to defeat him, proving that some things can cut deeper than steel.
Before you even attempt this make sure you make a manual save so that you can reload after as this will obviously cause any Pacifist attempt to end in failure. After you find Miller and get the choice to Stop Marchenko or to Save the Delegates turn away from Miller and enter the door in the corner. Follow the corridor to the end and enter another room at the end where you’ll find a computer on the desk. Look under this desk and you’ll find some bags, throw them to one side and open the hidden Weapons Briefcase to find Marchenko’s Killswitch.
Proceed to the boss fight with Marchenko and you’ll have to act quick and choose the option to “Use Killswitch” in order to obtain the Trophy/Achievement.
The Supreme Enlightened
You watched the End Credits and found the surprise inside.
Watch the credits at the end to view another cutscene and obtain the Trophy/Achievement.
I Never Asked For This
You completed Deus Ex: Mankind Divided on the highest possible difficulty. Hats off!
Deus Ex: Mankind Divided’s hardest difficulty unlocks after beating the game for the first time (which is good because you’ll want to be familiar with the game) and includes two nasty extras. The first is that you can only have one save file (that you can overwrite as much as you like) and the second, one life meaning that if you die, your save file will be erased and you’ll have to begin again from the beginning.
This shouldn’t be as daunting as it sounds as there are a couple of ways to get around this and we highly suggest you do this to save yourself a lot of pain. If you have a USB flash drive then you can backup your save to it so that if you die and your progress is wiped you can upload it and continue where you left off. The other way is to upload your save file to the PS Plus Cloud Save Storage so that you can access and reupload it should you fail.
As for the mode itself, it goes without saying that you should take a stealth approach and avoid doing any of the Side Missions (unless theres no danger of dying such as Side Missions 3 and 4) and complete the main missions only (this drastically shortens your playtime). You’ll want to invest in all of the upgrades to the “Glass-Shield Cloaking” augmentation and all of the battery upgrades to give yourself maximum upkeep of energy while cloaked. The rest of the playthrough should play out the way to tackled the main missions in your first playthrough (choose to head to the church rather than the bank heist when given the option at the end of Mission 10) and the path set out in this guide’s Walkthrough.
