Exploring the area around the Dunwall Tower | Mission 6 - Return to the Tower Dishonored Guide
Last update: 11 May 2016
The entrance to the Tower is heavily guarded, but you need to devote most attention to the watchtower shown in the above screenshot. Apart from "scanning" the image the area in front of the Tower, it has a wide range of rotation to the sides. Therefore, I recommend that you do not stay out in the open, and move from cover to cover. Further on, you can decide on the possibility of disabling the watchtower and, to do that, you will have to teleport to the top of the watchtower and remove the whale oil tank from the slot.
There is also a tallboy patrolling the area around the Dunwall Tower, which poses a considerable threat also. Fortunately, he is quite predictable in his movements so, after a moment's observation, you will have a clear picture of the situation and know what to do next, and when.
For starters, I recommend that you explore the warehouse located to the left of the mission target (the above screenshot), especially that this the area is not monitored by the watchtower. It is enough to wait for the tallboy to go the other way.
Do not attack the engineer here, and talk to him. You will learn from him about the possibility of lifting the nearby flood-gate, and thus gaining access to the moat that surrounds the main entrance to the Dunwall Tower. Have a look around the warehouse to find gold, food, Sokolov's health elixir, rewire tool and a book. Eventually, enter the room with a valve handle that opens the abovementioned flood-gate.
The area to the right of the Dunwall Tower Entrance is quite extensively developed (the above screenshot), but due to the presence of a watchtower and a tallboy, it is difficult to infiltrate it and stay in hiding at the same time. I recommend that you use the time hold power or teleport, but you can just as well access the area from the side of the Tower's main entrance.
You may now start exploring the buildings here. You need to watch out, not only for the guards, but also for the chambermaid, ho mustn't notice your presence here. If you intend to eliminate the enemies staying in the area, make sure that you conceal the bodies properly, as all the enemies remain in a constant movement. In the room on the ground floor (the above screenshot), you can find a rune under the bed, as well as gold, food, an Official Decree, Sokolov's health elixir, ammo and a book.
New Optional Quest: Find the Torturer's chambers
New Optional Quest: Kill the Torturer
You should definitely explore the upper level of this structure. Especially, you should turn your attention to the observation spot. You can find there a message (Off-limits), whose collecting unlocks a new optional quest connected with eliminating the Torturer. Apart from that, in here you can find gold, food, a grenade and a rewire tool.
