Xenogears Perfect Works ~The Real Thing~, known simply as Perfect Works, is a book covering the complex storyline of Xenogears. In addition, Perfect Works describes an enormous backstory of Xenogears, including canonical character details that never made it to the game's script.
Perfect Works also contains a timeline which some corresponds similarly to the Xenosaga series. It is presumed that, had the two remained in the same canon, that the book describes how they were meant to be linked.
Perfect Works has been fan-translated to English.
