The stealth mechanics are a tad wonky. Considering this, save early and save often, and remember that the enemies' radius of vision is pretty much bipolar. You'll be right up against them in some cases and they'll be unable to see you, while being hidden on the other side of the facility will somehow make them aware of your presence.
Ergo, Trick Number Two: Air ducts are your friends. No matter if they precisely know you're in there, they can't get to you. Nor will they think to throw grenades in. If you're caught, rush back to the nearest air duct and hide until the enemies conveniently forget about you.
It's just like Human Revolution - only clunkier.
