By all accounts, this is a solid DLC Level Pack. It's got new levels, new characters, and new weapons. They're all enjoyable, but compared to the main campaign, they feel a bit underwhelming. Still good, but not the cream of the crop that came before it.

Compare it to the Rayman Origins levels in Rayman Legends, or watching all the deleted scenes after watching a great movie. Worth your time, but definitely a step down compared to what came before it.
