It appears that Resident Evil 4 has accidently been released on the Japanese App Store, but not before Japanese site AppBank caught some video footage of the game along with some screenshots. The game has since been pulled, and I’m not sure when this game will appear again. It looks to be built off an improved game engine of their current Resident Evil: Degeneration, which has returned to the App Store recently after being pulled for uncertain reasons. If Resident Evil 4 gets released, it would be quite an improvement from the first one, and from the video I think it can be deduced that they have worked on the controls and the somewhat clunky interface. Stay tuned for more news (if any) on this game.
