Paper Mario: The Origami King

Paper Mario: The Origami King is the upcoming sixth installment in the Paper Mario series, set to be released on the Nintendo Switch worldwide on July 17, 2020. The game follows the aesthetic style of its predecessor, Paper Mario: Color Splash, and follows Mario opposing an evil army of origami characters known as Folded Soldiers, ruled by the Origami King, King Olly, which have taken over the Mushroom Kingdom.

Gameplay
The overworld exploration is quite different from the series' standard; whereas the previous three games were either sorted into individual chapters or levels, The Origami King switches to a completely open-world style of progression, with Mario being able to travel to any of the game's locales completely on foot like the first two games. The game's combat system has also been overhauled: at the start of each turn, Mario can rotate and slide rings of a circular battle arena, lining up enemies for consecutive attacks, although the number of ring moves and allotted time are limited. Mario has permanent Boots and Hammer attacks, and may equip stronger variants that break after a while. Attacking enemies on the overworld will grant Mario an extra attack in battle, and timed button presses can increase damage when attacking. Lining up the enemies successfully will increase Mario's attack power by a factor of 1.5. Coins can be spent to extend the time limit, or call the Toads that have been saved to assist Mario in battle. Boss battles use a different system in which the player rotates and slides the rings to line up arrows, making a path for Mario to attack.

Olivia, a character new to the franchise, has a role similar to Kersti and Huey from Paper Mario: Sticker Star and Paper Mario: Color Splash respectively. She grants Mario extended origami arms that are used to interact with the environment. Once certain bosses are defeated, Olivia can transform into the boss while standing on Magic Circles, an ability that carries over into battle. Additionally, partners return to ally with Mario and aid him in battles, including Koopa Troop members such as Bobby (a Bob-omb), Bowser Jr., and Kamek. Various partners join and leave Mario's party at various points in the story.

Accessories (which seem to function similarly to Badges from the first two games) grant Mario benefits both in battle and on the overworld. Toads can be found on the overworld, folded into various shapes. Hitting these Toads with the hammer will cause them to unfold and return to Toad Town, some of which open shops. The Toads that have been saved can even help in battle if the player spends coins using the Cheer command. These Toads will fight enemies, heal Mario, give items, and solve puzzles. Mario can gain confetti by using his Hammer on trees, grass, and enemies. This confetti can be used to fill Not-Bottomless Holes torn in the landscape, revealing Coins or a Toad.

Nintendo eShop description
 The kingdom has been ravaged by an origami menace! Join Mario and his new partner, Olivia, as they battle evil Folded Soldiers, repair the damaged landscape, and try to free Princess Peach's castle from the clutches of King Olly in this comedy-filled adventure, only on the Nintendo Switch system.

Mario and Luigi receive an invitation from Princess Peach to attend an origami festival and excitedly hurry to Toad Town...but something's amiss. After investigating the eerily empty town, the duo finds a fearsome (and folded) Princess Peach-she's been turned into origami by King Olly, ruler of the Origami Kingdom! With five giant streamers under his control, King Olly binds Princess Peach's Castle and transports it to a distant mountain as part of his plan to re-fold the world.

On his journey to liberate Peach's Castle and repair the ravaged paper landscape, Mario meets Olivia, King Olly's sister, and the two join forces to put a stop to Olly's origami onslaught. Even Bowser falls victim to Olly's plot when his minions are turned into origami Folded Soldiers and betray their Koopa king, forcing him to ally with Mario and Olivia!

Battle the Folded Soldiers in ring-based battles the challenge you to strategically line up enemies to maximize damage! Out of battle, Mario can use the arm-extending 1,000-Fold Arms ability in specific spots to interact with the landscape to pull, peel, hit, and more! Join Mario, Olivia, and their companions on a journey of laughter and emotion, thrills, and a whole lot of folding.
