Just started playing the demo of this game and I have to say I'm quite pleased with it so far. Only minor niggle is the camera every now and again but it doesn't make it unplayable.

Countering bad guys moves is strangley satisfying and so far it's looking pretty polished.

Check it out!

edit:

Just finished the demo and watched the preview movie. I can't effing wait until this comes out. It's awesome! I highly recommend you download it and give it a go.
