John L. Beiswenger, author of Link, filed a lawsuit against Ubisoft and their Assassin's Creed franchise. The lawsuit states that the plot of Link revolves around a device where ancestral memories can be accessed, recalled, relived, and re-experienced by the user which is similar to the Animus in the Assassin's Creed games. There are other citations made referencing religious similarities along with mentions about assassins in the book which was originally created in 2002. Beiswenger is seeking no less than $1.05 million for damages.
It appears that once the news started making the rounds, fans of the series have decided to take their own action against the author. On Amazon, Link has received a slew of new 1 star reviews, 38 at the time of the writing of this article.
