I won't go into detailed information about the game as this will spoil some aspects, I will say things that have been included in the demo version though.
As has been mentioned, this game is in the Devil May Cry vein, but it is a new type of game in itself. The control system is excellent in that there are literally loads of button combinations so you can tap away in whatever manner and you will pull of some good moves. Bayonetta can attack in a full 360 degree circle, she has four guns to make use of, two in the hands and two attacked to her ankles. She can flip onto her hands and so spin her legs around to shoot enemies which I find classic. Then there is the chance to unlock other weapons which can be bought with halos collected from killing angels, bosses and destroying scenery. And with Bayonetta herself, she can utilise her magic to form a "weave attack" which consists of enchanting her hair (which also forms her clothing) to attack with, this can be in the form of a giant fist or a beast that can crunch enemies. There are also special moves which entail punishing enemies, you can hurl them into an iron maiden or put them into a guillotine, these are moves that can be performed during fights as you build up your magic meter which is great! You can also buy more moves and items to regain health, magic from the shop. The storyline is quite lighthearted and the "english" accent of Bayonetta is quite amusing. The cutscenes can be viewed as a bit odd by some people but I feel it tells the story well enough, there will be stills as from a mvoie reel rather than charcters always moving when the cutscenes occur. The indroduction of "witch Time" rather than block is a great inovation as it means you cannot just stand there and take what enemies throw at you and take no damage, you have to doge the attack and if you time it right the Witch Time gives you a few seconds of speeded up play where you can pound the enemies even further. The bosses are a bit surreal in looks, some have the face of a baby for example, but his just adds to the game's uniqueness. For this price, the game is well worth the buy! And if you like trophies it is challenging to try and aquire them, so gives a lot of reply value, and you will not be able to collect all the items, weapons on just one play through!
