Be wary of this one, as it's a genuinely dreadful game. Any game that pits a sexy vampire assassin against nazis and STILL manages to be dull is doing something seriously wrong.Combat is flat and lifeless, graphics are uninspired and there are far, far better third-person action games out there.
The sequel improved massively on the original and was actually a playable, enjoyable game, so if you absolutely must have some vamp action, I'd wait for that to turn up instead of wasting your time on this. This wasn't even a good game when it was released, and time (coupled with the recent surge of quality third-person action games) has just made its failings all the more obvious.
