The Mario + Rabbids Kingdom Battle Season Pass adds a separate Donkey Kong campaign, extra solo Challenges, co-op maps and weapon packs. The base game is required. The Gold Edition includes this content, so check your edition before buying the pass separately.
Donkey Kong Adventure
Play a separate island campaign with Donkey Kong, Rabbid Peach and Rabbid Cranky. The four areas are Banana Lagoon, Reef, Jungle and Dungeon. The expansion becomes available after completing Ancient Gardens in the base campaign. Its heroes and equipment belong to this adventure; buying it does not add Donkey Kong to Mario’s regular main-story party.

Ultra Challenge Pack
The pack adds eight difficult solo Challenges, with two associated with each world’s secret chapter, plus five additional co-op maps. These are distinct from the forty regular world Challenges included in the base game. Complete the relevant campaign and secret routes before looking for the additional challenge locations.
Weapon packs
The Pixel Pack supplies eight weapons with an 8-bit appearance. The Steampunk Pack supplies eight weapons with a mechanical theme. There is one weapon for each of the base game’s eight heroes in each pack. Select available equipment through Battle HQ; downloading a weapon does not automatically equip it.
