'''Foxiest of the Hounds''' is an Achievements and Trophies (DX3)|achievement/trophy in'' Deus Ex: Human Revolution''. It is earned by completing the game without setting off any alarms.
The easiest way to track this achievement is to check whether you get the Smooth Operator bonus for completing a specific main mission objective, list of which you can find below.
It should be noted that simply getting all the bonuses does not guarantee the acquisition of the achievement. If, for example, the player leaves a body of a knocked out enemy in a place where other patrolling guards may potentially find him and completes the objective fast enough he will still get the Smooth Operator bonus. But eventually the body will be found and guards will sound an alarm (it may even happen out of player's sight), which in turn will nullify the Foxiest of the Hounds. So it is recommended to play cautiously and not to trust the XP rewards too much.
For the general strategies on playing stealthily consult the guidelines listed on the Smooth Operator page.
==List of objectives in Deus Ex: Human Revolution that award Smooth Operator bonus==
There are 21 Smooth Operator bonuses available in the game (22 with bonus mission from Explosive Mission Pack DLC).
Note that "Investigating the Suicide Terrorist" objective has two mutually exclusive ways of resolving it, so it's possible to earn either Silver Tongue bonus or Ghost+Smooth Operator bonuses in Police Station, but not both. If player chooses to talk his way into the morgue this WILL NOT COUNT AGAINST the Foxiest of the Hounds achievement, meaning that player will need to earn only 20 (21 with DLC) Smooth Operator bonuses out of possible 21 (22) for the achievement.
Also note that "Place the C4 on Administrator Wang's Desk" will not provide a notification upon completing the objective, as it is followed immediately by a cutscene and you are taken to the Omega Ranch. You can confirm that you got the bonus by checking your experience when you regain control of Adam (1000 + 250 + 500 for Ghost if you got it).

*This achievement/trophy is a reference to the http://metalgear.wikia.com/ Metal Gear Solid game series where an identical achievement is also present in the latest titles. The main character, Solid Snake, was a member of a black ops group, "High-Tech Special Forces Unit FOXHOUND". Also, the visual representation for the achievement/trophy is a masked guard with exclamation points above his head, a common sight in all Metal Gear games.
