When I first got Dishonored when it came out, I decided to do a no-kill run. Eventually I got to the point where I had to take an audiofile to Slackjaw but before I can complete the task, apparantly as a result of some weepers or something, everyone goes hostile. I decised to set the game down for a while in the hopes a patch would fix it, but their appears to be no patch, but I haven't bought the DLC.
I am willing to use a cheat code or something to get past this bug. I would really like to finish this no-kill playthrough. Is there anything I can do? Does the DLC fix this bug?
