A top tier DLC add on for a game. While there may seem to be not many new bosses at first, with only 5 main and the final boss, these bosses are amazing, diverse, challenging, fun, and the most well animated bosses, more than the base game. Not only that, but you also have this King Challenge to help give you coins instead of generic levels, and it is more challenging but more fun. The music is also top tier for the series as well. This DLC is basically ESSENTIAL for anyone that liked the base game.
