How to unlock the All of the Above achievement in DEUS EX: HUMAN REVOLUTION - Definitive Guide
Note: The actual area to do this is after you go down/up the elevator and meet the doctor and arrive back in the detention area. You will then be told that the doc & prisoners are being poisoned.
You cannot get both this and Factory Zero in the same playthrough (without reverting to a previous save).
In order to get this you need a gun, the lift heavy objects skill and the jumping skill.
When the poison gas is released and you head to the bottom of the prison section, instead of heading to the middle, go to the SW of the outside edge. There is a large crate you can move (with super strength). to reveal a grate. Go into the duct to find a small room. With super jump, you can jump onto the pipes and up onto a ledge, then through another vent. This leads you into a room with a green gas canister on the side opposite where you enter. Go up to it, aim your gun and shoot the container to save everyone and pop the achievement.
The other solution points out the method, but just so you are aware: You can destroy the crate with an explosive barrel, snag 2 cardboard boxes and a fire extinguisher and drag them through the air duct that was behind the crate. Use the boxes to jump on in order to get to the next duct, bring the fire extinguisher and chuck it at the gas canister.
You don't even have to go to the mission specific location for this one - I never initiated the standard cutscene of the mysterious guy telling me to choose.
Achievement popped AND I still got Factory Zero. Easy peasy.
After Burke attempts to kill Kavanagh and the prisoners with the gas, you will be given the option to save one or the other. If you are doing a Factory Zero playthrough, save now. Pick up a gun, or equip one if you already have one in your inventory. Take the Cybernetic Leg Prosthesis and Move/Lift Heavy Objects augmentations and find a large box covering a vent on the outside wall. Follow the path and it will lead to a generator with a small green tank on the front. Shoot the tank and you will save everyone and get the achievement, but to get Factory Zero you will need to reload your save and choose one or the other.
First and foremost, when you get to the holding cells (big, circular 3 level room with the security tower in the center) look at the northeast corner: there is a big crate over a vent. This is where you need to get to in order to obtain this trophy, and what I am going to describe is how to set this up so when Burke releases the gas you can easily get to this room without any trouble whatsoever.
STEP 1: Take out the 3 guards on the ground level, and the one dude in the security room. Easy enough - just use all takedowns. There are plenty of energy bars and packs all over the place prior to this area, so if you have to use them.
STEP 2: Find the big crate as referenced above. You should notice the vent behind it. If you are going for Factory Zero, you will notice this thing is impossible to move without your strength upgrade, but that is ok. You have some explosive barrels (red with the explosive icon) on this ground level. Pick one up, and hurl it at the crate (R1). The crate is no longer an obstacle.
STEP 3: Locate 2 cardboard boxes and 1 fire extinguisher. Take these items through the vent, and orient the boxes in a way to get you to the grate above the pipe in the small room. There is another vent that will take you into another area: bring your fire extinguisher into THAT room.
STEP 4: Proceed with the game.
After you confront the scientist (Kavanagh) and get her to supply evidence to Interpol, you proceed back to the holding cell area and are instructed to go beneath the security tower. If you follow the game, a timer will start and you will have to backtrack to the area you made ready for this trophy...
OR
You could just go to where you set up everything. You should see something lit up green in the room you left the fire extinguisher. Pick up the fire extinguisher, and hurl it at the green display thingy: it will blow up, a hacker will speak and the trophy will pop.
And you did it without using any praxis kits!

Missable! Right after Burke discovers Keitner's plan and fatally wounded her to the point that she dies. Burke will then begin to flood underwater base and the prison cells with toxic gas to remove any and all potential witnesses. Jensen only has 10 minutes to save Dr. Kavanagh and the prisoner's lives, but he will only have the option of diverting all the gas to one of the two areas; either save the lives of hundreds or Dr. Kavanagh who is the only person that can truly testify against Belltower. However despite all this, there is a third option that Jensen can take to save Dr. Kavanagh and all the prisoners at the same time. In order to pull this off you need any lethal weapon (pistol, combat rifle ect.), the Move/Throw Heavy Objects and Cybernetic Leg Prosthesis - Jump Enhancement Augmentations. Now simply move the large crate out of your way in the same area to find a hidden vent. Crawl inside and using your Jump Enhancement augmentation, jump onto the pipes and into the upper area. In this hidden room, Jensen will find the source of the gas dispenser so destroy it with one shot from your gun and the trophy will unlock. Video credit goes to PragPD.
Factory Zero Method:
There's another way to save Dr. Kavanagh and all of the prisoners without using the augmentations or a weapon. This method is difficult to pull off, but it's 100% the Factory Zero way. In order to do this method you'll need a small cardboard box and a fire extinguisher. Both of these items are inside the prison area on the lower level. When you first enter the area, stealth your way across the area and jump on the pile of bars with a cardboard box on it. Grab the box and carefully stealth your way towards the vent behind the crate you can't move. Carefully lay the cardboard box down and open up the vent. The vent will move the heavy crate out of the way slightly, now place the cardboard box right against the heavy crate and the vent and simply drop it. Now all you have to do is move Jensen forward by using the cardboard box to move the heavy crate out of your way. When you moved it away enough, you can grab the cardboard box and take it with you through the vent. Now place the box on top of pipe and quickly catch it as it's falling. You should have caught it in face-up position, so carefully lay the box there in front of the pipe. Now Jensen can use the box to jump on the pipes. When the time comes to save everyone, you'll need to stealth your way to the fire extinguisher, which is in the center of the area near the staircase. Once you have the fire extinguisher you have to jump onto the box and carefully lay the fire extinguisher on the top area. Now crouch and grab the cardboard box and place it onto the pipe you're standing on, then jump onto the box again and climb to the top and take the fire extinguisher with you. In the room with the gas dispenser, simply stand in front of the gas and throw the fire extinguisher at it. You'll destroy it and since the fire extinguisher isn't a weapon, it won't count against your Factory Zero trophy. All of this can be seen done in the Factory Zero Video Walkthrough. To view it done in the video watch 26:10-29:40 and at 55:10-1:01:30.
At the end of the hole there will be a room in which you need to climb up through the pipes, there will be another hole at the end of which there is a room with a unit that distributes this very poisonous gas.
It is necessary to break (shoot) the flask with gas (the place on the screen where the flask was marked in red).
And the trophy is yours.
Truth be told, as I found out a few days later, if you go around this box (which covers the ventilation) from the other side, then it’s quite possible to get through there without implants.
