Audio Amplifier

The Audio Amplifier Implant amplifies the footsteps of nearby enemy troops, causing them to appear on your Proximity Map. (Normally you need line-of-sight.)

This Implant can be countered with the use of Sensor Shield. Note that this implant works even against enemies who walk/move while crouched. There is a known bug in which enemy players who recently exited a vehicle (via bailing or dismounting) are not always detected with the implant.
