Beginning six years after the events of Resident Evil 2, the fourth game in the series takes place in Europe. It follows a former police officer named Leon S. Kennedy, who is now working for the United States government. Leon is sent there on a top-secret mission to investigate the disappearance of the president’s daughter Ashley. As Leon faces atrocities beyond his worst imagination, he is compelled to discover the identity of the entity or entities responsible for everything. As Leon investigates the kidnapping of the president’s daughter, he runs into familiar faces—and foes—at every turn. He is determined to find out who is truly responsible for the crime.

When compared to the previous installments, Resident Evil 4 represents a significant departure. The game utilizes a new “behind the back” moving camera angle as opposed to a fixed third-person perspective. Additionally, the game has an “over the shoulder” aiming function that enables players to control the movement of their rifles in order to attack certain body parts. It has a fresh new artificial intelligence engine and more open surroundings, both of which make it possible for foes to collaborate in order to capture and corner Leon. The adversaries are now shown as people, giving them the ability to open doors, climb ladders, and wield weapons as they go through the game.

Additionally, the entire item system has been reworked, and as a result, smaller goods will no longer take up an entire item space when they are stored. Instead, each object takes up a certain number of blocks of space in a briefcase proportional to its actual size. This makes room for a significantly greater number of guns and other items. When Leon defeats adversaries or finds riches in the environment, he can take it to the famed “merchant” to exchange it for larger briefcases, treasure maps, weapon upgrades, and more powerful weapons like the one-shot RPG.

There is also the Mercenaries DLC for Resident Evil 3, which enables the player to take on the role of a character like Hunk or even Albert Wesker himself in order to participate in survival situations.

Separate Ways is a supplemental narrative mode that, unlike the initial GameCube release, is included with later platforms and may be played once the player has completed the main game and obtained all of the game’s achievements. This story allows you to take on the role of Ada Wong and takes place in conjunction with the main narrative. It reveals to you what Ada did, who she communicated with, and where she went when she wasn’t with Leon. There are several wholly new levels, as well as some of Ada’s own gadgets that have not been seen before in the main tale. However, most of the locales and weapons remain the same.
