Along with Harry Harris, she joined and aided James Taylor and Gary Stewart during their mission. She is first mentioned by G at the beginning of the game's first chapter, before appearing with Harry after James and Gary defeat Judgment.
She is seen again along Harry near Sunset Bridge or on a motor boat with him (depending which path the player takes) before and after James and Gary face Hierophant. She and Harry commandeer the boat throughout the game's third chapter before the two head to the Coliseum after receiving a phone from Caleb Goldman, telling the agents to meet them at the coliseum. Harry, sensing it's a trap, asks James and Gary to head into the sewers while he and Amy head straight there.
After James and Gary destroy Tower, they receive a call from an alarmed Amy that is cut short because of a giant monster attacking her and Harry. The creature is eventually identified as Strength, the boss of the game's fourth chapter. When James and Gary arrive at the Coliseum, they are greeted with a pre-recorded message by Goldman himself before Strength is unleashed again.
After James and Gary defeat the creature, they are given the keys to a car by a wounded Harry, with Amy staying with him to tend to his injuries. Amy can be seen again in the game's normal ending along with Harry, G, and other citizens cheering for James and Gary outside Goldman's headquarters.
