Fans of Resident Evil are well aware that Resident Evil 4 was quite a departure from the series. Not only did it ditch the franchise's trademark zombies in favor of "Invasion of the Body Snatchers"-style monsters and change to a more action-oriented style, but it also skipped many years ahead. A lot of things occurred during that time gap, but Resident Evil 4 was mum on the details. The previous Wii game, The Umbrella Chronicles, was focused on what happened to the pharmaceutical company Umbrella and its biological monsters between Code Veronica X and Resident Evil 4. Even with an entire game dedicated to bridging the gap, some questions were still left unresolved, particularly involving Krauser, a man who claimed to have some history with Leon S. Kennedy during that time gap.
