Maya Visari, or Echo (2366-), is the deuteragonist of Killzone: Shadow Fall. She is a intelligence operative for the Helghast living on Vekta during the events of game. She is also a half-breed (meaning she has both Helghast and Vektan blood). Having similar orders as protagonist Lucas Kellan, whom she allies with later on in the game, she will stop at nothing to get the job done. Echo is voiced and portrayed by Jamie Gray Hyder.
