Good way to kill a weekend
While the FPS aspects of the game are decent, a lot of it seems like it could have been on a last generation console. The whip mechanics when playing as the boy are horrible, especially when trying to swing from one area to another.
The storyline is good enough (probably the best aspect of the game) and the ability to switch between to the two characters is a novel trick as far as the plotline of the story goes, but adds little to the fun of playing the game.
I would rent this game to get a taste of it, but don't waste your money (or your time) buying this.
