Mario + Rabbids Kingdom Battle now offers a Season Pass. The $19.99 add-on will get you a few trinkets at launch, with the promise of more game content later on.

The XCOM-inspired, turn-based role-playing game puts guns in the hands of Nintendo’s cuddly cast of characters for the first time. They’re joined by Ubisoft’s Rabbids, and will have to fight to restore order to their respective worlds.
