After being leaked earlier this year, Ubisoft used E3 to officially reveal their crossover mash-up RPG Mario + Rabbids: Kingdom Battle.

The game is a massive departure for both franchises. It’s a tactical, turn-based RPG in a similar vein as Firaxis’ XCOM reboot in terms of gameplay.

The Rabbids and the inhabitants of the Mushroom Kingdom need to team up after an interdimensional rift brings the Rabbids to Princess Peach’s domain. You’ll explore a Mushroom Kingdom that seems to have been transformed somewhat by the arrival of the crazy, rabbit-like creatures.

Combat sees Kingdom Battle take on the look of a turn-based, tactical RPG (albeit a cute and colorful one). Battles play out with each character moving in turn. Characters can move and perform attacks, as well as combine to pull off special moves or move further across battlefields.

Mario + Rabbids: Kingdom Battle launches exclusively on Switch on August 29, 2017.
