Seems like a reasonable price for a decent DS game:
Play as either Joe or his sister Jasmine
Use the touch panel to solve puzzles and pull off special moves
Keep track of the action in two viewpoints, with the dual screen
Wild new DS-only powers -- Shake the screen by touching it, or split the screen in half by using the special Power Split move
While filming a movie in the Movieland theme park, a group of nefarious robots known as the Madow steal the film from under the casts' noses. As Viewtiful Joe, you'll head off into the recesses of Movieland, solving puzzles and heroically bashing your way through wave after wave of Madow chumps. Now Joe can use his powers in the real world, with the handy V-Cam -- as long as it films him, he has access to all his powers, plus a few new ones.
