The balance between the sound of gunshots and footsteps is not right.

The gunfire is so loud that it hurts your ears, and the glare of the bullets when they hit you makes you lose the outline of your enemy and lose sight of him.
However, only the footsteps are so low that you cannot hear them at all.
I would like to see more balance and finer volume settings. The gunshots are too loud and I want to turn them down, but when I turn them down, the other sounds disappear.

For some reason, the enemies turn black and become invisible when you are in a building or just in the shadows.
This spec is not improved at all either.

Cheetahs have also started to increase.
The opponent forgets to hide behind obstacles and kills the opponent using only the power of the machine's aim.
It's become a surprisingly boring game. 
I hope they fix the problem ASAP.
