Less than 8 hours to finish!!
First things first. Graphically this game is exallent, reflections appear to be realistic, and the shadows are spot on. Even the lens flair and the moment of every thing being out of focus when you come up over the edge of a building. Sound, very good, VOs are fairly convincing and match the characters appearances, weapon sound effects are quite good and the fact that while running across a rooftop you can hear Faith breathing heavily is a nice touch.
The actual gameplay is the best thing about this game (obviously) and the free-running aspect of the game is very entertaining for the first half of the game, however the second half you'll probably find yourself looking for an enemy to disarm rater than a way to get around them as it is mostly indoors which renders the free-running somewhat limited, that being said, you'll still find some areas which you'll most likely remember for a while, such as the first time you train-surf or the bit where you have to jump between two massive cranes, although I was a bit disappointed that you don't ever get the chance to jump clear over a helicopter and the fact that when you really look you'll notice that the game is very linear and utterly devoid of any real exploration to find a suitably path. Also of note is that some areas can become tedious, such as trying to get to the rifle in the second half of the game (took me 4 attempts and a few goes of the time trial mode)
So in closing I give this game a * rating of 7 as it is a good game but it fails to accomplish exactly what i was hoping for.
