Capcom has released an iPhone version of Resident Evil 4.
You take the role of Leon Kennedy, an agent sent to Europe to rescue the president’s daughter. In the process Leon confronts a dangerous religious cult, fighting it with large array of weapons.
The game is rendered in real-time 3D, and uses an interface similar in concept to Resident Evil: Degeneration. Players can target individual bodyparts, and reload by shaking the handheld. Finishing the main storyline unlocks Mercenary Mode.
Resident Evil 4 costs $8, and runs on iPhones and iPod Touches running v2.2.1 firmware or better.
