Today, were extremely excited to announce DropMix, a brand new game that were making in partnership with our friends at Hasbro. DropMix is a fast-paced music mixing game where players create one of a kind mixes by playing cards featuring hit songs from award-winning artists. Its completely unlike anything else youve ever played and we hope it will give you that same deep connection to your music and your friends that our previous fan favorites like Rock Band or Dance Central have offered.
