The novels often took liberties with the plot of the games by exploring events

The novels often took liberties with the plot of the games by exploring events occurring outside and beyond the games.

Perry's novels were translated and released in Japan with new cover arts by Wolfina.[46] Perry's novels, particularly The Umbrella Conspiracy, also alluded to events in Biohazard: The Beginning, such as the disappearance of Billy Rabbitson and Brian Irons' bid to run for Mayor.
