Unfortunately, there's not much to look for here in terms of story. Like most shooters, including the first Army of Two, the story just seems to be there to provide players with a reason to bounce around from one objective to the next. It also seems to be lacking a lot of the humor of the first game. That's not to say the humor isn't there of course. The game just does not go out of its way for the sake of the joke all the time.
