<P> There are significant tie - ins with the Assassins Creed Unity Companion App, a "freemium" click app with limited "direct ties to the overall story of Unity". There are a significant number of chests, assassination targets, and other collectibles that are visible to all players but only accessible to those who have completed certain goals within the app . Following an update in February 2015, this requirement is no longer necessary, meaning players who have downloaded the update, can now collect all the chests in the game without having to play the companion app . </P> <P> The main character of the game is Arno Dorian (Dan Jeannotte), a native Frenchman who was born in Versailles to an Assassin father . After his father is killed by Shay Patrick Cormac at the end of Assassin's Creed Rogue, Arno is adopted, unaware that his new family holds a senior position within the Templar Order, with his new father figure being the Templar Grandmaster . Arno blames himself when his adoptive father is murdered, and so sets out on a quest of redemption that brings him into the Brotherhood of Assassins, where he slowly rises through the ranks, much like Altaïr Ibn - La'Ahad and Ezio Auditore da Firenze as seen in previous games . Arno's love interest is a Templar named Elise De LaSerre (Catherine Bérubé), the daughter of the Templar Grandmaster who adopted Arno, who also sets out to investigate more about her father's death and its role in a growing ideological change within the Templar Order that threatens its core values . Additional characters include Marquis de Sade (Alex Ivanovici), Napoleon Bonaparte (Brent Skagford) and Maximilien de Robespierre (Bruce Dinsmore). </P> <P> Arno's story starts in Versailles as a child, but for most of the story he is in Paris . His adventure in Paris starts on the eve of the French Revolution in 1789, and extends up to the Thermidorian Reaction in 1794 . The modern day setting focuses on the Assassins contacting the player and requesting their help to explore Arno in the past, as well as helping in the present . Co-operative multiplayer missions follow the development of the Brotherhood of Assassins during the French Revolution . In addition, "time anomalies" are introduced during the story . Accessing them takes Arno to various points of Parisian history, such as Paris' Belle Époque, or its occupation by Nazi Germany during World War II . </P> <P> The "Initiate" is a player of Helix, a gaming device produced by Abstergo that allows access to many different genetic memories . </P>
