It may not be a new platformer but this is pretty hype!
Ubisoft showcased Mario + Rabbids: Sparks of Hope during their Ubisoft Forward today, and the action started off with footage from a Wiggler boss battle. If you missed that portion of the presentation, you can find it above.
Along with that, Ubisoft also revealed that Rayman would be made available in Mario + Rabbids: Sparks of Hope through DLC. You can see the teaser trailer for that DLC below.
