The water in this apocalyptic sewer runs pretty rapidly, it seems—or else the dripping water sounds almost like a heavy rain. I almost expect a canoe to come floating down the corridor. I think I hear rats scrabbling around, and maybe something even more threatening. The track is skillfully executed, but I have a slight concern that it might be too distracting. A GM using this soundscape should keep that in mind and monitor the volume carefully. But other than that, it’s got a wide range of applications, and would work just fine not only in the post-apocalyptic setting suggested in the title, but in any adventure that takes the characters into the sewers.
