XIII is a first-person shooter video game developed by Ubi Soft Paris and published by Ubi Soft for most platforms except for the OS X version, which was published by Feral Interactive.[1] Loosely based on the first five volumes of the 1984 Belgian graphic novel series XIII, the protagonist Jason Fly (XIII) is a confused and amnesic man who searches for his identity throughout a comic book-style, cel-shaded world. Found stranded on a beach by a lifeguard, Fly is accused of having killed the President of the United States. The accusation later transpires as mistaken, as Fly finds himself facing a gang of 20 conspirators ("The XX") who aim to overthrow the government.
