マリオ＆ルイージRPG ブラザーシップ！

The brothers return for a brand new adventure on the high seas! Set sail with Mario and Luigi on Shipshape Island (part ship, part island) and journey through the vast world of Concordia. Launch out of Shipshape’s cannon to visit, explore, and quest your way through islands that range from tropical rainforests to bustling cities. Meet new friends along the way, like Connie and Snoutlet (who's definitely not a pig), and encounter familiar faces from the Mushroom Kingdom like Peach and Bowser, who may help you on your journey! You’ll have to rely on Mario and Luigi’s brotherly bond to succeed. Use Bros. Moves to get past obstacles while you explore, and powerful Bros. Attacks in a dynamic twist on turn-based combat. You’ll need every edge this 'brothership' will give you to save the day!

When a mysterious portal opens in the Mushroom Kingdom, Mario, Luigi, and many of its residents are swept away to Concordia, a world once bound together by a great Uni-Tree until a dark force shattered it into islands adrift across a vast sea. Aboard the mobile Shipshape Island, the brothers befriend Connie and the pig-like Snoutlet and set out to reunite the scattered lands, seeking each island's lighthouse to reconnect it to their new home. As they journey, they uncover the sinister power spreading isolation across Concordia and must draw on their bond to bring the fractured world back together.
