Good but not perfect
First off, this game lacks realism. I mean, one guard can take up to 5 freakin' kunais in the chest? C'mon! And if they have bulletproof vests, then there's no way in hell a kunai would make them bleed; let alone kill them. Second, I experienced aiming problems; ie, I aim at the head, and yet my weapon hits the chest.
Now, what I like about this game is its plot. Like all sift head games, this one has a nice story to it.
Personally, I found the first SHW game better in terms of replay value. But that's just me.
In overall, it's an average shoot 'em up game.
