Have worked my way to the final level, which I should conquer this weekend. One of the things I like about this game is you have to take your time in the fire fights, you can't run toward the vilians and blast them, taking cover is important.
The game also has some cool weapons, in the Venice level I used the TND 16 ARO Scope which was really cool.
On the downside, the game is really just one long fire fight in different location, warehouses, barges, trains, etc. The locations are interesting, but exhibiting some other skill, like driving, would have been cool, and a little change from the constant gun battles.
I also think the comments that the single player is very short is not true. I don't keep track, but playing at the second level I am sure I have spent at least 10 hours playing. My son playing at the easy level spent about 8 or 9 hours playing, so I think their is some single player value.
One additional small criticism, previous Bond games have worked in some curvacious ladies, but much like the Craig films, this game is lacking in any female talent.
