This track delivered exactly what the name led me to expect: white noise (as of engines), pinging, and the occasional sounds of metal striking metal, or metal bending. The only thing missing is people. This submarine sounds like it’s deserted — which makes the track kind of spooky. Great for a “monster aboard the submarine” type of scene, or the exploration of an abandoned submarine; not so great for a wartime scene where the PCs are the submarine crew.
