Aliens vs Hyperdimension Neptunia is an upcoming fanfiction crossover between the Alien franchise and the PS3-exclusive JRPG series Hyperdimension Neptunia. It is to be the sequel to a only recently started fan fiction crossover with the latter series and the Shadow, which is set between the second and third Neptunia games following the second's canoncal ending. The plot will be set after the canoncal ending of the third Neptunia game, Hyperdimension Neptuina: Victory. It is planned to be published on fanfiction.net within the summer.
Nothing is known about the plot as the creator of the first Neptunia fan fiction has only had the first chapter published. However, the epilogue will introduce the Aliens and the sequel will follow. A new version of an alien queen and a new Neptunia character that are connected is also set to created to help tell the plot.
