I would have probably been done weeks ago if my OCD didn't make me have to destroy every single pixel on the screen. Still it's a nice game to take your frustration out on, by beating the crap out of inanimate objects... and some animate ones.
Decent game with some pretty fun mechanics. The various ways to kill all humans is pretty fun but the storyline kind of drags on. The cut-scenes (while well-acted) go on too long and leave you just wanting to go back to killing. Toward the end of the game, I found myself skipping dialogue.
