Xbox 360 How is this game?

[Xiaou]

I have a small obsession with Helicopters, and the idea of a flight combat game focusing on Helicopters sounds amazing.

However, I'd like to hear the communities thoughts, demo aside, I don't know much else about it - or if it's any good.
I know this game isn't exactly new, but it's something I've been putting off so much, maybe it's time to just go and get it!

Any opinions would be appreciated.
