Action adventure platformer Waltz and Jam coming to Nintendo Switch 2.

Action adventure platformer Waltz and Jam coming to Nintendo Switch 2. Krafton, in partnership with Flyway Games, made it known today that Waltz and Jam will be launching on Nintendo Switch 2. The game comes out on December 3, 2026. Waltz and Jam is an action adventure platformer, which reimagines the Seven Deadly Sins. Players will visit seven distinct realms, solve environmental puzzles, battle foes, collect mysterious tools, and face towering bosses while heading toward the Gate of Judgement. More information can be found in the following rundown: Waltz and Jam is an action-adventure platformer following Waltz, a pure-hearted soul, and Jam, a lovable shape-shifting dog. Journey through the afterlife where the Seven Deadly Sins are reimagined as seven vivid realms. Solve puzzles woven into the world around you, topple mighty bosses, and complete your ticket to enter Uptown. JAM, YOUR BEST FRIEND IN THE AFTERLIFE Jam is far more than an adorable pup. He's Waltz's dearest friend and truest partner on this journey beyond! Transform Jam into a Jam Water Ball to bounce and splash, a Jam Trampoline to soar! Mix Jam's wonderfully wacky transformations with Waltz's toy skills, and together nothing stands in your way. With Jam by your side, the sky's the limit, no puzzle too tricky, no darkness too deep to brave together. CURIOUS TOYS, NEW WAYS TO PLAY Scattered across the worlds are toys, each waiting for someone to pick them up, each hiding a peculiar power that aids Waltz on his journey. Put them to clever use to trigger strange contraptions, open hidden passages, and send pesky foes flying. Every new toy unlocks another way to unravel the world, and the path you've been searching for might be hiding right under your nose. SEVEN SINS, SEVEN STORYBOOK WORLDS Follow the mysterious Low through seven handcrafted worlds, each reimagining one of the Deadly Sins through its own peculiar hue and mood. From a restaurant clattering with chaos to a castle tangled in light and shadow, to a desert that rolls on like an endless sea, every realm turns like a page in a hand-painted storybook, each with a look all its own. Uncover the tales and secrets tucked into every corner, and solve each world's puzzles to unearth its treasures. But don't let the pretty scenery fool you! Something spookier always lurks just beyond the page. THE BOSS BATTLES, EVERY TALE ENDS IN A TRIAL! At the end of each of the seven worlds waits a towering boss, swallowed whole by the sin it embodies. Read its every move, find an opening, and use your toys, Jam's transformations, and even the environment itself to turn the tide. Conquer each colossal trial and claim its stamp, and with every victory Waltz and Jam draw one step closer to Uptown. Nintendo News has got a release date trailer for Waltz and Jam below.
