So far I'm liking it. Some pretty good action scenes that I felt were original

The airport massacre scene for one.


My complaints so far is that, for the emotions I think they try to convey, it just seems too fast paced and that the guns, while varied, all just seem the same power-wise except the BAR.

Then opening "cinematics" for each level are awesome, and they do something special in each level which sorta breaks the monotony of shoot -> run -> cover -> shoot; my only beef with this, so far (I've just started it), is that they failed to carry the mood set by the opening or at least, in-level, while face-paced the atmosphere just seems to flat-line. /over-analyzation

Can't really give it a rating 'cause I've played so little of the single player, but its more than decent so far.
