Game is frustrating because you have to sneak into a camp with a zillion enemies and find the right tent.
Area is crowded (both NPCs and tents) and visibility is poor:
You can't scope out the area from a distance and get a clue where you're heading.
With limited supplies you're allowed to carry, it makes saving the game outside the starting village a problem: You wont be able to replenish supplies until you beat the stealth camp.
Added to this is the "quick reversal" the NPCs do, making it dangerous to move once they turned away, and you have 1 or 2 others coming at you from other angles.
Because the area resets every time you enter: ducking into a tent to avoid guards is not an effective strategy, even if you remember which ones are empty.
Never found the one with the "back door" mentioned by someone else.
Even beating the enemies quickly in battle doesn't help: you get pushed back to previous area.
