I rented this from gamefly I got it on Wednesday and I sent it back Thursday.
It wasn't a bad game it was just reallly really repetitive. You start out in a mini movie and the first level teaches you how to play the game. Everything is in black and white except I think the blood that's red. But the game is pretty violent you basically have a chainsaw in your right arm which your arm is mechanical.
The levels go you kill enemies then open up a mini game which you kill more people then the boss level opens up. The only boss I had trouble with was the 4th boss I believe he was. But you just have to get into a cut scene move the wiimore or nunchuk in the position it says and your done and you do some damage. You can also just beat the guy up without hitting the cutscene but that does take a few lives to defeat the boss.
Kills what makes this game so gory I guess is that you do kill people but the people are bad guys. You get points from killing people the more gruesome the more points you get. You need points to open up the minigames and the boss level.
What you can do and to get more points you have to screw the people up. So what you can do is say pick up a tire throw it around the dude, then grab a sign post and push it through the dudes neck then pick him up and throw him into spikes.
I also found in one of the levels there is a aquarium of piranas and you can throw people into it. My favorite kill was I found 2 trumpets and shoved them in the guys ears. He started to honk the horns it was pretty awesome. There are also grinders I threw a bunch of people into meat grinders that was awesome.
The game wasn't bad but it's just really repetitive which I didn't like. I don't think the game was that hard but just interesting and a good way to get agression out if you need to. I wouldn't pay full price for it though.
