The character makes her debut and only appearance in 2010's
Heavy Rain, developed by French studio
Quantic Dream. She is introduced in her apartment, being unable to sleep. After taking a shower and trying to sleep once more, she notices the apartment has been broken into. The two invaders then attack, though ultimately are revealed to be a nightmare caused by Madison's poor sleeping. Madison then goes to a motel to try to help her sleep, where she meets other protagonist Ethan Mars, who has been injured after attempting the Origami Killer's first trial in order to find his son (who has been abducted by the killer). Though she doesn't know the cause, she helps him to his room and treats his wounds. Later in the game, she tends to Ethan's wounds again after he tries to complete another trial. After this, Madison helps Ethan to avoid the police who now believe him to be the Origami Killer, though whether she is successful depends on the player's actions. After they return to the motel, or after Ethan arrives having escaped the police station after being freed by another of the protagonists,
FBI agent Norman Jayden, she learns why Ethan is now on the run, and that he is completing trials to find letters of the address where his son is being held. Madison begins her own investigation, beginning by questioning Adrian Baker, a fired surgeon who now illegally deals medical supplies as drugs. If the player does not have Madison leave after finding evidence leading her to the club, or has her drink Baker's secretly drugged drink, she is knocked out and wakes up tied to an operating table. If the player fails to escape here, Madison will be killed and removed from the game's future chapters. If she lives, she will then go to the Blue Lagoon and interrogate Paco Mendez, the club's owner. After Paco leads her to his office to be private, he pulls a gun on her and forces her to strip. After stripping clothes until the player manages to surprise hit Paco with a lamp, she ties him up and begins questioning him. Next, she goes back to the motel and talks with Ethan. Madison leans in to kiss Ethan, and the player, as Ethan, may choose whether or not to embrace her, leading to a sex scene, or reject her. After the sex scene, Ethan finds her photos and the beginning of a story about him as the possible Origami Killer. As Ethan, the player may choose whether Ethan tells her to leave, ending the romance, or forgives her. Whichever the player chooses, Madison leaves, and notices the cops. The player may have her warn Ethan, who may or may not be arrested depending on the player's next actions as him. She then visits Ann Sheppard, an old woman suffering from
Alzheimer's disease and the mother of two sons, one of which drowned in rainwater in a hole in a construction site, and the other who was then adopted. Madison finds the identity of the killer, Scott Shelby, and investigates his apartment. There, she may find the address where Shaun Mars, Ethan's son, is being held. Shelby eventually arrives, and sets the place ablaze while Madison is still there. Madison may die in the blaze, or the player may manage to have her escape. If she escapes and has found Shaun's location, the player may have her phone and tell either Norman or Ethan it, or have her go there alone. If the player fails to find the address and/or dies, she will be removed from play for the final level where the killer is confronted. The ending epilogue will show different things for Madison depending on the player's actions and choices over the game. She may be shown starting a family with Ethan and Shaun, being with Ethan as he shoots himself over his son's death, sitting in her apartment with worsened insomnia, signing copies of a book about the game's events, or if she died a shot of her grave may be seen.
The Taxidermist Heavy Rain Chronicles: The Taxidermist, a downloadable prequel for the game and an update to an earlier demo, stars Madison. Intended to be the first in a series, the rest of the
Chronicles were put on indefinite hiatus after work on a
PlayStation Move version of the main game began. Madison, investigating the Origami Killer, intends on interviewing Leland White, a
taxidermist and possible suspect. However, when she arrives, he is not home, so thus she sneaks in. In his house, she discovers a murdered woman in a bloody bathtub, and in another room numerous stuffed and posed corpses of women. Depending on the player's actions, Madison may end up sneaking out without Leland noticing, be noticed but manage to escape regardless, kill Leland, be killed herself, or phone the police and hide until they come. ==Development==
