Early impressions? Visually stunning, by console standards possibly raising the bar, perhaps the best looking console game made to date.
It's taking a little while to get used to, I didn't start on the recommended difficulty, I went a bit higher because I like a challenge. The controls are a little jerky, I'm not a huge fan of the way the player moves, but again I think that's just getting used to it.
Opening sequence was epic, voice acting seems very good.
One complaint, these displays you use for changing weapon where you point your analog stick in the direction of the bit you want on the circle, it works well when you use north, north west, east, east west and so on, but as games try and incorporate more and more into this type of menu it becomes a bit chaotic.
