Mother 4: Forever is a fan-made sequel to the Mother/EarthBound cult-classic RPG series that will never be released. Mother 4 is currently under development, and will likely never leave development, but if the planets align and pigs start to fly, it will be playable on PC, Mac, Linux, and The Gamesphere.
The story follows Travis Touchdown, who is a stereotypical otaku – his motel room decorated with professional wrestling and anime collectibles – living in near poverty in the No More Heroes motel of the fictional town of Santa Destroy, California. After winning a beam katana in an internet auction, he runs out of money to buy video games and wrestling videos. After meeting with Sylvia Christel, he accepts a job to kill Helter Skelter, also known as "the Drifter," which earns him rank 11 by the United Assassins Association, a governing body of assassins. Realizing that he has the opportunity to make it to the top, he sets out to secure himself the coveted position of number one assassin in the UAA.
After killing the tenth ranked assassin, Sylvia reveals that if Travis stops killing, he'll eventually be targeted by other aspiring assassins. Travis, now convinced there's no way out, goes on to kill every other assassin except for number eight, Shinobu, whom he spares because he wants her to get stronger. Along the way he meets Henry, a mysterious Irish man who wields a beam katana similar to Travis' own.
Before meeting the top-ranked assassin, Travis is told that the UAA was just an elaborate con set up by Sylvia, who overheard his drunken ramblings and organized his entry so that he could finally have revenge on his half-sister, Jeane, who murdered his parents. Jeane reveals in a fast-forwarded cutscene that their father had sexually abused her all her life, thus forcing her to become a prostitute to survive and become a killer. Travis is eventually saved by Shinobu and kills Jeane.
The game ends with Travis being attacked by another assassin before Henry saves him, and challenges him to one last fight. It is during this fight that Henry reveals two twists: first, that he is Travis's twin brother, and second, that Sylvia is his wife (which would make her Travis' sister-in-law), and has a habit of disappearing before returning with lots of money (presumably due to conning people). Still locked in combat, the brothers discuss the nature of these revelations and their situation while they run down a long street. Finally, as the two leap towards each other for the final clash, the screen flashes and is revealed to be a painting hanging in an art gallery, where a little girl, Jeane, and her mother, Sylvia, are observing it.
The game is never gonna be released BTW.
