Description: Discover where your enemies are hiding! Hear every sound they make!
Upgraded: User has the ability to X-Ray through walls and see foes.
Echoer is a Gene Tonic which enables the user to hear where their enemies are in an echo-location sort of way. Once upgraded to level two, the user can see though walls, with the user able to X-Ray Splicers and Big Daddies. X-Rayed foes will take a double damage boost and head-shots will deal more damage, with regular shots able to pierce through the tough armor of Big Daddies, Big Sisters, Alphas, Big Brothers, and other armored Splicers.
