I spent way more time than I'd like to admit trying to navigate through the Massachusetts State Home yesterday, what a nightmare. I figured it was full of raiders, took a couple out and then I heard more talking but could NOT find them. I went through every room a dozen times til I found out how to go deeper into the building(which I STRONGLY recommend you do not do without having very strong firepower, seriously...).
So I get down there and survive a nightmare battle I won't spoil for you, then I finally discover those two raiders I overheard an hour prior in a totally different part of the building higher up, and after what I just went through to find them they were barely relevant anymore lol. I was so lost for the longest time, and after I finally cleared that hellhole I get out and realize I'm missing Strong. Had to go back in and search all over again to find the big green moron. Anyway, my point is that the voice displacement was a major contributing factor to my dizzying confusion in that place lol.
