The player controls Leon S. Kennedy from a third-person, over-the-shoulder perspective in a mission to rescue the daughter of the President of the United States, Ashley Graham.
The gameplay focuses on action and shootouts involving crowds of
enemies in large open areas. The camera is focused behind Leon, and it
zooms in for an over-the-shoulder view when aiming a weapon.[2]
Unlike previous games in the series, there is the addition of a laser
sight that adds a new depth to the aiming, allowing the player to aim in
various directions and easily change their placement at any time.
Bullets affect the enemies specifically where they are shot: shots to
the feet can cause enemies to stumble, while shots to the arms can cause
them to drop their weapons.[3]
Leon in battle with a group of Ganados. Unlike previous entries in the series, Resident Evil 4
places the camera constantly behind and over the protagonist's
shoulder. The laser sight enables the player to target key hit zones on
enemies.[3]
Another new aspect of Resident Evil 4 is the inclusion of
context-sensitive controls. Based on the situation, the player can
interact with aspects of their environment: kicking down a ladder,
jumping out of a window, or dodging an enemy attack. There are also
dynamic cut scenes,
in which the player must press buttons indicated on-screen to execute
actions such as dodging a falling boulder or wrestling an enemy to stay
alive. These are often incorporated into the game's many boss battles,
where the player must avoid instant kill attacks.[4]
The main enemies are violent villagers referred to as Los Ganados ("The Cattle" in Spanish). Los Ganados can dodge, wield melee and projectile weapons, and are capable of working collectively and communicating with each other. They were once simple farmers until becoming the product of an infestation of Las Plagas ("The Plague" in Spanish).[5]
The inventory system of the game features a grid system, represented by an attache case, that has each item take up a certain number of spaces. The case can be upgraded several times, allowing for more space. Weapons, ammunition and healing items are kept in the case, while key items are kept in a separate menu. Items may be bought from and sold to a wandering merchant that appears in various locations throughout the game. He sells first aid sprays, weapons, allows for weapons to be upgraded and buys various treasures that Leon finds. The various weapons each have their own advantages and disadvantages.[6][7]
Capcom added new content made specifically for the PlayStation 2, which was later incorporated into the PC and Wii releases. The largest addition is "Separate Ways", a minigame which revolves around Ada Wong's involvement in Resident Evil 4 and her connection to Albert Wesker, a former member of STARS, who is now attempting to revive Umbrella.[8] "Ada's Report", a five-part documentary, analyzes Ada's relationship with Wesker and his role in the plot.[9] Other unlockable content in all versions included the minigame "The Mercenaries", "Assignment Ada", a small minigame using Ada to retrieve plaga samples, new costumes for Leon and Ashley, new unlockable weapons and a Movie Browser.[10]
