Warzone 2 and Modern Warfare 2 will receive audio improvements with the Season 2 Reloaded update

Many activities simultaneously take place in the game, such as grenade-induced explosions, killstreak activations, background announcements, gunshots, and more. Unfortunately, the footstep audio is quite low on the titles' priority list, resulting in it not being heard when other activities are taking place near the player.

For example, if a Mortar Strike is being used on Ashika Island, enemy footstep audio will be disabled due to that activity being louder. This will be adjusted in the upcoming update, after which the footstep volume will be increased.
