This mod merely lessens the quantity of footsteps in CoM: Final Day and Arsenal Overhaul by adjusting their unique output by -12.5db (roughly 25-30% quieter), so that they are not so overwhelmingly distracting. All while footfalls on most surfaces have been afflicted, all those on/in h2o have been left at their unique quantity to sustain realism. This mod (most likely) lessens the seem of NPC footsteps as perfectly, but so much I have not seen a distinction in gameplay.
