@GazzaGarratt MW19 footsteps are the loudest of any COD without question.
The MW2 beta footsteps are the 2nd place.
All the older Cods, Cold War and Vanguard have the counters in perk form for the footsteps.
I understand full blown tactical sprinting should be louder. Also the variation of different surfaces should change the volume. E.G running up or down metal stairs or the likes.
I don't find the MW2 Beta footsteps unbearable, but there is advantages with good headphones and bass boost turned on. Veterans can pinpoint directions and abuse it.
Another point I would like to make is campers triumph with louder footsteps. It's very hard to counter or sneak up on them if they are in a corner and they can hear you in advance before you reach them and they can ADS and prepare or turn round to catch you coming.
It's more magnified in game modes like SnD when it's a 1 life deal and every decision is crucial.
I would rather get destroyed by someone rushing with great gun skill and silent footsteps, than some dweeb in a dark corner that heard me long before I arrive to their dwelling.
All and all there should be a balance and the option to track enemies audibally and visually, but not too over the top.
If everyone has quiet footsteps and you get decimated, you weren't aware of your surroundings visually and that's on you. Unless by exception there is a heavy spawn trap in place.
Now if a perk like ninja exists it will be used excessively.
If none such thing exists, dead silence as a field upgrade will be used by most and then all the other field upgrades will not be looked at or utilised in any way.
