I've seen some other people to say that this has happened them too. I play in ps3 and I’ve never had any problems with Dishonored up until I bought Dishonored: Game of The year Edition, now I don’t is that the reason or not. However game works beautifully up until the point where you have recovered Corvo’s gear. (I don’t know what happens if you don’t get them, I usually prefer clean hands way so the gear is kind of important.) When I enter the Rudshore Waterfront where is this room full of dead overseers, immediately as I enter the detected sound and combat music start playing. (I know that there is one whaler up ahead, but he can’t see Corvo without door begin open and you standing near of it. and even when you take him down problem won’t go away. Even in that room after that is just Corvo, dead overseers, River Krusts and dead/unconscious assassin.) As I continue through that area the detected sound plays almost all the time. I make sure that no one has seen me. Reloading a save game doesn’t help. This is annoying glitch in the area that is already tricky because assassins are much harder to spot that any normal enemies. Is there anyway to fix this? Dishonored is one of my favorite games, and it makes me sad that suddenly something like this happens.
