While in the sewers, make sure that your take downs do not throw any guards/gangs into the electrocuted pathway! Otherwise, bye bye pacifist
-Anytime you do take downs, make sure the enemy is displaying the zzzz icon and NOT the skull sign
-Some instances where could cost you Pacifist (save these people)
-1) Save the hostages when Purists have taken over Sarif. You can use the ventilation system here to land right beside the hostages.
NEW: some people are syaing this is not a must. I recommend you save them anyways
-2) Save Grog Thorp's wife (she is the lady taken by Sanders). You can get another achivement for convincing Sanders to release the hostage.
-3) Saving Malik! Make sure you have plenty of energy bars to replenish your energy here for take downs and cloaking system. Target the enemies that do the most damage. Robot> Heavy soldiers> Snipers> Machine pistol. Note: You will need an EMP grenade for the bot. Either use the stun gun or make the soldiers unconscious. However, before the EMP explodes, you need to drag the soldiers out of the blast radius of the explosion (Otherwise, bye bye Pacifist). Check whether the icon on the soldiers display a skull or zzzz. If a skull is displayed, realod a checkpoint. I found the skill that increases your energy points very helpful.
NEW: I recommend you start on the right hand side and jump on the trash can to the next floor. Take out the 2 guards (the skill with double take down helps). Secondly, Jump down and knock the heavy guards unconscious. Thirdly, throw the EMP greande at the bot while pulling the unconscious bodies away.
Note: the double take down skill also helps.

NEW: some people are syaing this is not a must. I recommend you save her anyways
-4) Saving both the doctor and the prisoner's in the missing link dlc. There is a ventilation system that lets you access the source of the poison gas. it is blocked by a big box. You will need the skill that lets you move heavy objects. Alternatively, you can use smaller box to push the big box out of the way.
-5) NEW: the intro counts towards the Pacifist. Therefore, do not kill any guards.

-Note: If you fail a hack, you lose Foxiest of hounds. According to the wiki, even if you fail a hack at Sarif, you will lose Foxiest of hounds (I lost mine on Director's cut b/c I did not know this)
http://deusex.wikia.com/wiki/Smooth_Operator
If you do not believe me, read smooth operator triggers.
-Manually check to see if you have gotten the smooth operator for some quests (Not all have it)
Website here:

-What happens if the Guards become suspicious? You are fine
-What happens if the alarm system becomes suspicious? You are fine
-What happens if the alarm system becomes Alarmed and makes beeping sounds? You lose Foxiest of hounds. Re-load the save. Note: This is different than suspicious. You hear a loud siren.

-You CAN talk to Haas at the Police desk station. You won't lose foxiest of hounds this way. However, you cannot earn both silver tongue and smooth operator/ghost together.
Personally, I recommend sneaking into the police station.
-I recommend you avoid confronting Tong for the silver tongue. Therefore, sneak into his office
NEW: you can enter the Hive from the back alley. The garbage bin is blocking the way to the ventilation system.
- I recommend you avoid confronting Tagger for the silver tongue and find Sandavol Location from the computer in the room near by
Here are the screenshots: Use the tunnel in the bathroom. By using the ventilation system, you can drop in the room with 2 computers to get Sandaval's location.

Somebody said this
"Missing Link DLC and how to circumvent the missing Praxis points/other routes to get around or ideal Praxis point usage up until you see Quinn. Also mention that the Stun Gun sets anyone who gets hit by it to Hostile status before vanishing away, and if you use it on the Cameras or Bots -- there's a cooldown timer like 3-4 seconds before it turns back on but it doesn't set either to Hostile status."
