Resident Evil 4 takes place six years after the Raccoon City incident, following the U.S. government's investigation and subsequent shutdown of the Umbrella Corporation. The story follows Leon S. Kennedy, a former rookie cop turned U.S. agent, who is tasked with a critical mission to rescue the President's daughter, Ashley Graham, who has been kidnapped by a mysterious cult called Los Illuminados in a remote European village. The game revolutionizes the series with its innovative third-person perspective and cinematic wide-screen view, featuring an intuitive aiming system that allows for precise location-based damage. Players can strategically target enemies' specific body parts for different effects, while context-sensitive controls enable smooth execution of complex actions. The game also introduces a comprehensive weapon upgrade system where players can use in-game currency obtained from defeated enemies and pawned jewelry to enhance their arsenal through the mysterious 'Arms Merchant', ensuring survival against increasingly challenging threats.
