That's the vibe I get. There's a part where you need to kill a woman that owns a brothel. You can charge in guns blazing and win, or you can sneak in, lure guards away with whistles and kill with bear traps, set your two guys up to distract one, sneak into the brothel, steal some laudanum, poison the woman's whiskey, and then escape out the front door when the guards leave.

But if you fuck up the stealth, you can always shoot your way out!
