Crime Boss: Rockay City

This was actually very easy on the second try. I recommend restarting the game until you get a roll of the level where you can take the tunnel under the diner to the pier. Subdue any guards that might be lurking on the docks (just those in your path), then make your way up a ladder into the bow of the ship. Quickly, and obviously quietly, subdue guards on the ship as you encounter them. Don't bother hiding them, because ideally you will be done before anyone will find them. Do it if you are paranoid, but you will waste valuable time. Break open the Russian stacking dolls and golden bust of Khan as you find them. On the lower deck, check the cabin drawers and shelves for moveable laundry. There are a couple evident crime scenes on both the middle and upper decks of the ship, and one on the bottom deck. These are where the bulk of your loot will be found, but which scenes have loot is random. Get all that loot to the dinghy moored at the aft of the ship (or once on a neighboring pier). With a little awareness of guard locations on the ship, this should be pretty breezy, and you ought to wrap up before the detectives arrive. Note that once the detectives arrive, they wander around the whole ship and are likely to stumble on any guards you've subdued, and they can't be dealt with silently as far as I've been able to tell - this is why you need to finish BEFORE they arrive. A person on your radio will keep you posted on how much time you have left.
