Action, Fighting, Multiplayer
Kirby: Battle Royale (sometimes written Kirby Battle Royale), known in Japan as Kirby Battle Deluxe! or Kābī Batoru Derakkusu!, is a game in the Kirby series set to release in January 19, 2018 in North America. However, it will release on November 30 in Japan, and on November 3 in Europe. It is a multiplayer action fighting game that will release for Nintendo 3DS in celebration of the Kirby series' 25th anniversary. The game features single-player as well as local and online multiplayer. While Kirby Battle Royale is not the first Kirby game with online features, it is the first to allow players to play directly with each other over the internet.
An image from the official Kirby Twitter in the series of "Bandana Waddle Dee's Battle Deluxe News!" pictures was recently released featuring Sword Kirby staring in surprise at three other Sword Kirby's wearing different costumes: one based on Gigant Edge, one based on Dyna Blade, and one based on an origami samurai hat made from newspaper. It's likely that other abilities will have alternate costumes as well, in a similar manner to Kirby Fighters Deluxe.
Gather! Apple Match (あつめて! リンゴマッチ): Team-based mode involving apple picking. Players collect apples from Twin Woods and deliver them to their base. One player can collect apples while the other operates the machine to collect the apples. Seems to also include an icy stage without Twin Woods. 
Battle Arena (バトルロイヤル, meaning Battle Royale): Standard free-for-all.
Treasure Hunting (トレジャーハンティング): Kirbys collect coins in a haunted mansion, but have to avoid the floating skull which will drain their money.
Attack Riders (アタツク ライダーズ): Mode involving collecting money from other Kirbys; a Wheelie can be driven to give the player an advantage.
Fly! Rocket Race (とばせ! ロケットレース): Kirbys collect green cubes and take them to their rocket, then ride their rockets to see who gets the highest.
VS Robo Bonkers (VS ロボボンカース): Players attack Robo Bonkers to obtain points.
Smash Hockey (スマッシュホーカー): Players knock around a giant hockey puck. Hockey puck can be hit with enough strength to instantly knockout another player on contact.
Ore Express (ぽいぽいトレイン, Poi poi torein, meaning Warm-Hearted Train): Players collect stacks of ore and dispense them into train carts.
Flag Shoot (フラッグシュート): Players in teams bring a colored ball to their flag.
25th Anniversary Poll
On the Official Kirby Website, there was a poll in which individuals could vote for their favorite Copy Ability; the Copy Ability that wins the poll may have a chance to be added into the game. Copy Abilities in this list which are already included in Kirby: Battle Royale are marked with Pink Star (a Kirby face). Copy Abilities marked with Red Circle cannot be added to the game. Every standard Copy Ability except for Smash Bros. is included. Voting was allowed once per day until the poll ended on October 2, 2017. The winner will be announced November 7; this means that, if applicable, the winning Copy Ability will not be available at the release of the game, possibly becoming downloadable content.
Abilities in Bold are already included in the game, abilities followed by a star (*) cannot be added.
As of September 23, 2017, the highest voted Copy Abilities were:
Excluding 3D Classics: Kirby's Adventure, which released before the launch of Miiverse, this is the only Kirby game for the Nintendo 3DS that did not have a Miiverse community. This is because the Miiverse service was discontinued on all devices on November 8, 2017, before the game's launch.
Likewise, this is also the only Kirby game for the Nintendo 3DS that cannot be played with stereoscopic 3D.
This is also the third Kirby game that won't release in Japan first, and the second game to be released in PAL/Europe first (the first game in both instances being Kirby's Avalanche).
Bandana Waddle Dee seems to be Kirby's partner/helper in Story mode, as seen in the trailer.
Nintendo UK's Copy Ability Poll states that Cleaning Kirby debuted in 2009. This is because Kirby's Dream Land 3, the origin of the ability, was not initially released in Europe. European audiences first got a chance to play it when it was re-released on the Wii Virtual Console in 2009.
Nintendo of America's copy ability poll says that Parasol debuted in Kirby Super Star. This is an error, because it debuted in Kirby's Adventure.
The same poll before also states that Bomb debuted in Kirby's Adventure, but it actually first appeared in Kirby Super Star.
The Japanese title may have been chosen to avoid association with the controversial 2000 film, Battle Royale.
Despite being one of the first different-colored Kirbys in the series, Red Kirby has yet to appear, seemingly replaced by Orange Kirby.
