Junk Fu is packed with eight achievements totaling 50 gamerscore. The gadget will be free for a limited time. From now through Sunday, you can snag this download for no charge, but come next Monday the gadget will jump up to an unspecified price (likely 240 MSP).
Although it requires a Kinect Sensor to play it would be worth downloading in case you get one in future to save you the MS points
Thanks
