First..... if you have the chinese stealth suit, use the special mirolurk 'Shady Hat' that Moria gave you along with the stealth suit.
If you don't want to use the stealth suit then wear no armor at all and use the Shady Hat. Be prepared to possibly take a hit but
if you get the first critical hit then you should be able to defeat the enemy before they can attack.
I have noticed something about the Dart Gun use...... If you hit the wall around an enemy, the enemy will run to the wall and investigate the
dart. Sometimes, it is almost as if they investigate the dart and then backtrack from line of sight to where it might have been fired.
Recon an area for things you can hide behind; fire a dart at a wall, when the enemy backtracks to the spot where you fired it they will
eventually turn their back on you and you can leap out and get the job done. I use a ripper......... or sword or combat knife or
supersledge or............................
It would be nice if you could throw a pool ball across a room to make an enemy investigate the
noise...... then sneak up on them while thier back is turned....
