Why is the Flex perk not working? Warzone players demand fix for inconsistent audio issues

Flex was designed to reduce combat noise and make it easier to hear enemy footsteps, but Warzone’s audio issues have prevented the perk from working properly.

Players can only use one tier-three perk at a time, and it’s not an easy decision. Ghost jumps off the page as a great option after the Dec. 14, 2023 update, as it hides operators from UAVs, Portable Radars, and Heartbeat Sensors. High Alert also has plenty of fans, as the perk provides an alert when an enemy is looking in your direction.
