Resident Evil 4 - E3 2003 Beta Trailer [High Quality]

This main game, an action-adventure shooter originally released in 2005, shifted the series with its over-the-shoulder third-person perspective, enabling faster gunplay. You play as agent Leon S. Kennedy, sent to Spain to rescue the President's daughter from a hostile cult. Distinctive features include larger environments and smarter enemy AI that coordinates attacks and uses the environment. The core loop involves tense combat, resource management, and exploration against tactically aware adversaries.
