The first game in Capcom's blockbuster survival-horror series designed with a real-time 3D polygonal engine, Resident Evil 4 is freed from the camera limitations and static backgrounds of past titles. Players guide Leon S. Kennedy, the lead protagonist in Resident Evil 2, in an adventure taking them deep within the Umbrella Corporation. The result is a battle for survival as players confront mutated biological experiments, zombies, and other creatures of suspicious origin. Leon comes equipped with a revolver but will still be able to find various other weapons along the way. Environments include rain-soaked alleyways, decrepit sewers, and castle-like structures. Hiroshi Shibata, who previously worked on Resident Evil 3, makes his directorial debut in this game, with Hiroyuki Kobayashi (Dino Crisis 2, Devil May Cry) serving as producer.
