New Super Mario Bros. 3 (Sonic for Hire and The Random Block)

New Super Mario Bros. 3 is an upcoming side-scrolling 2.5D platform game for the New Nintendo 3DS and Nintendo Switch. It will be the fifth and latest installment in the New Super Mario Bros. series. It will be released worldwide on September 09, 2018, and will be the second New Super Mario Bros. game not to include Bowser Jr., the second New Super Mario Bros. game not to include the Koopalings and the first New Super Mario Bros. game to feature Mark.

Story
Standing on the balcony of her castle, Mario, Luigi, Wario and Toad wave goodbye to Princess Peach to fly in their capes. After the flight begins, they discover Mark running through the grassy field. However, as soon as they return, Bowser suddenly appears, grabbing them with a giant mechanical fist, as well as damaging Mario and co., making them lose their cape power-ups. Bowser reveals that Princess Peach is possessed as "Princess Faker". The giant mechanical fist launches the heroes towards the Chestnut Hills. Mario and co. crash into a tree. Mario, Luigi, Wario, Toad, and Mark then tumble out of a tree while they're at it, and look into the horizon to see Bowser beginning a possession from Princess Peach's Castle to Faker's Castle, setting Mario and co. to go on a new adventure and stop Princess Faker.

As the game progresses, the view occasionally shifts to Peach's Castle being possessed, showing the flags being replaced by dark blue flags with Faker's crown and the castle being surrounded by a thin tornado-like cloud that is made thicker, entirely obscuring the castle. Mario, Luigi, Wario, Toad, and Mark also have to deal with Bowser's forces, including his minions and Fake Bowsers. None of them is enough to stop the heroes from progressing. Mario and co. head out into Shish-kebab Castle. However, they reveal that Faker is now in her now-possessed castle.

After reaching Faker's Castle and defeating Bowser, the group moves onward, but Faker appears and spreads her magic across the arena. After heading into the castle exterior, Mario and the others see Bowser now in a giant size. Eventually, Bowser is defeated, but Princess Faker appears in an attempt to stop Mario and the gang. After defeating her and the regular-sized Bowser in his Koopa Clown Car (equipped with both its boxing gloves and a Missile Bill Blaster), Faker is changed back into Princess Peach, and Mario (or Mark) gets to bows down to her, and is then kissed by her, to their shock and delight, as the clouds surrounding the castle disappear, changing Faker's Castle back to Peach's Castle.

Gameplay
The game now features a 5-Player Multiplayer and Boost Mode. This time, Boost Mode is controlled by Mark. Strongly based off the other New Super Mario Bros. games and Super Mario 3D World, most of the elements and design make a heavy reference to Super Mario Bros. 3 and Super Mario World. The goal is to collect 1,000,000 coins. Getting 1,000,000 coins will award a new title screen with a Gold Mario statue. The reward for maxing out the coin counter at 9,999,999 coins is both a Gold Cape Mario Statue and Gold Mark Statue.

Power-ups return. The game introduces also two new power-ups: The Super Berry, which transforms Mario and co. into their weasel forms, giving them the ability to scratch enemies with claws, run at a crouching height and sprint quicker (not as Wario); and the Invincibility Feather, which transforms Mario and co. into their white cape forms, giving them the same abilities as Cape Mario or Superhero Wario, as well as being invincible. Every time a White Cape character defeats an enemy, they will get bonus points or 1-Ups.

The camera angle can change dynamically in some levels where Cannon Warp Pipes and Clear Pipes are found, showing more areas and perspectives of the scenery.

Playing as Mark
Instead of playing as Mario in Single-Player mode, the game introduces Mark. He cannot use power-ups. A new Rocket Launcher appears, making Mark blow multiple projectiles he collects. Using the Rocket Launcher, Mark also can build defending places.
