RE4 Wii Edition is simply the best version of the game.
As for the story goes for anyone who isn’t that familiar with this game or any of the previous game(s). The story of the game starts off with Leon S. Kennedy. A survivor from the tragic zombie outbreak that had accrued in Raccoon City in 1998. Now he is on a mission to find, and rescue the President’s daughter from a kidnapping that has taken place, and as he struggles along the way to find her leads in a European village of crazed Spanish peasants. Now Osmund Saddler, a leader of the village's religious cult, Los Illuminades. He has brought an infection to all of his followers with the Las Plagas. It is a parasite that will control anyone who is too weak to control it him or herself.
The control layout for the Wii version is rather nice, you use the B to aim and the A button to fire. You use the Z down on the nunchuck to do a turnaround, and C & Z to zoom in and out with the rifle or rocket scopes, and you can either swing the Wii remote to slash with the knife, and to automatically open crates, or you can either hold down C & press the A buttons to open crates, or you can hold down C and move the knife around on what you want to slash, and to move the camera angles you just use the d-pad on the remote.
The only thing that kind of bugged me at first is the Wii remote cross hair when it’s not in use. I would have like it if the cross hair is off the screen at all times, and the only time it will show up is when you hold down the B button to fire. Its not that bad you’ll get use to it, I just distracted myself at times wiggling it around the screen.
This is the best version out of all the previously released ones. If you haven’t played Resident Evil 4, or your just looking into picking up the Wii version for the extra content and Wii functionality. Then defiantly its a must buy, and at a budget price of 30$ is a pretty good deal for such a great game!
