Resident Evil 4: Wii Edition includes the bonus content from the PlayStation 2 version and introduces several changes to accommodate the Wii Remote's motion controls. The aiming system features a larger reticle that changes from green to red when targeting an enemy, replacing the original narrow laser sight. A "quick knife" command is added, allowing automatic targeting of the nearest enemy or object, and motion-sensitive quick-time events supplement traditional button prompts. Visually, the game is comparable to the original GameCube version and generally improves upon the lower-resolution graphics of the PlayStation 2 release. However, a few graphical elements-such as low-detail herb models-appear to be carried over from the PS2 version. The Wii Edition also supports the classic controller, restoring traditional controls and the original laser sight aiming. Additional differences include a lower overall difficulty and slightly faster animations for Leon's actions.
