This game is amazing, pushing the DS to its limits. However, they still don't have replay value down.
Now the gameplay is as good as it gets for the DS, utilizing the touch screen to look around, the D-pad to move, and the bumpers to fire. A, B, X, and Y aren't really used at all, unless you play lefty. This game has a perfect environment to scare, but also draw you into the story and your surroundings in the game. The monsters look better than the first game, and the sound quality was upgraded, giving a clearer in-game music to creep you out.
Overall, worth playing or even buying, but i suggest renting or borrowing because it truly is an awesome game.
