I picked up a copy about 2 hrs ago and have been playing it since, the first thing that I have noticed is how similar it is to Return to Castle Wolfenstien in style and spirit. This is not a Call of Duty World at War style game, this is an old school 1 man vs an army of nazis shooter,
The viel powers give it a slightly Bioshock esque feel and are fun to use, and the shooting system is very well thought out,
On the negative, there is excessive cut scenes and loading times and there does seem to be some graphical glitches and slow down.
This is by no means the technical masterpiece that the call of duty games are, but then again it is not trying to be, this is a throwback to games of a few years ago, just with modern graphics and effects, it works very well.
