The game takes place in a world where Mario and his friends are enjoying a peaceful day in the Mushroom Kingdom. However, their fun is disrupted by the arrival of a mysterious and powerful entity known as Mr. L. This evil character has brought along his Rabbid minions, causing chaos and destruction throughout the land. It's up to Mario, Luigi, Princess Peach, and their Rabbid allies to team up and stop Mr. L's evil plans.
: A standout feature is the movement system, allowing characters to "team jump" off allies to reach further areas or perform "dash" attacks on enemies during their movement phase.
: Making up roughly 65% of the game, combat requires players to use cover, elevation, and unique character abilities. Characters like Mario can use "overwatch" techniques to attack moving enemies, while Rabbid Peach provides essential healing.
