Marvel Ultimate Alliance 2 is a reasonably good-looking game, but there are some problems that are heavy enough to bring the whole game down a few notches. The environments and character models look really nice; all of this gives the impression that the game aspires to be like the console versions. However, the framerate chugs even when there's nothing of importance going on. This dampens any sense of satisfaction you might have gotten had the action been more fluid. Another huge issue is the camera. You have absolutely no control over the angles, and you'll get lost several times. You'll have to resort to the in-game map, which you must pause the game in order to access. It would have been nice if the touchscreen was used for the map, but that would probably have made the top screen far too busy.
MUA 2's sound design is unassuming throughout. To be fair, it's not bad. For the most part, activating powers will trigger an appropriate sound and the music is passable. However, none of this stuff is particularly befitting of the Marvel superheroes. If every part of the sound package was layered onto a generic action game, it would have worked just fine.
