Walkthrough:Prowling the Grounds
"Prowling the Grounds" was the main hub for "Tide of Terror" in Sly Cooper and the Thievius Raccoonus.
Walkthrough
First section
After being introduced to Bentley's holographic markers, head forward and latch onto the hook to your left, and allow it to pull you down to the rocks below. From there, you can leap across the debris of items in the water below, where you will find your first Lucky Charm. From the lifeboat docked right beside the ship, ascend the rope to get onboard.
In this section of the hub are the first four missions: "Into the Machine," High Class Heist," "The Fire Down Below" and "A Cunning Disguise." "Into the Machine" is located off to your left once you get onto the boat. Ahead is a wide walkway with a squid guard patrolling around; this is where you can access "High Class Heist." Right beside the entrance to this area is a breakable window with an item behind it (either a life or a Lucky Charm). Off to the right of the wide walkway, when heading backward, is a breakable window, which also can have either of these items behind it. You can access it by leaping onto the railing and then a tree.
As you head towards the right side of the ship, you will find a turbine to your right, which will help you access "The Fire Down Below." Run along it to get it to roll and lower down an eagle's nest. Once it lowers down, jump onto it and let it raise you up. From there, you can swing across to the tall structure. Ledge-sneak around to the left to find the entrance to the area. A path stems directly from where the turbine is, leading to the backside of the ship, where you can grab onto a pipe and climb to the rooftops. Here, you will encounter another squid guard, patrolling at the end. Here, you will find the entrance to "A Cunning Disguise." At this point, you would have collected at least three treasure keys. Head over to the generator to unlock it, then destroy it to disable the electricity in the tube.
Second section
Once on the other side, your next task before confronting Raleigh is to gather two more keys to unlock a nearby cannon. Two more mission areas are found here, and they are "The Gunboat Graveyard" and "Treasure in the Depths." To access "The Gunboat Graveyard," simply head up the small path that spirals up around a tower-like structure, then carefully leap across to the rooftop with the squid guard patrolling around the entrance. To access "Treasure in the Depths," simply follow the path leading directly from the cannon. You will also find an extra life on a platform off to the right. Once these two missions are complete, you will have enough keys to unlock the cannon. Once unlocked, simply jump inside to have it shoot Sly up to the storm machine.
Also note that this is the only hub level in the game in which the player can collect extra lives or horseshoes already lying around. They usually appear in between missions but may not be found all the time.
