Attack Riders is one of the ten game modes in Kirby Battle Royale. Players attack in a ring-shaped arena for ninety seconds and can ride a vehicle to get an advantage. Each player starts with 100 chips; the player/team with the most points wins. It is unlocked by default. The mode has similarities to Coin Battle from the Super Smash Bros. game series.
Attack Riders is first played in the first Bronze League Battle in Story Mode.
Players attack each other in order to steal chips; stolen chips are automatically collected and put in that player's backpack. If a player is KO'd, that player will drop chips that can be picked up as an additional penalty, along with receiving a notification of who they were "done in by." A vehicle will appear in the center of the battle ring to eventually be accessible to the players; vehicles are gray when not mounted, but change to blue or red depending on the player riding it. Players riding a vehicle can move, jump, and perform a powerful charge attack. Players can be forced off the vehicle by taking damage. After enough time has passed, a second vehicle will appear.
Attack Biker has two large platforms and lets players mount the Blaze Wheelie, which can perform a dash attack as its charge move. It takes a while to charge and has a slow turn. If two opposing Blaze Wheelies dash into each other, they will rebound.
Attack Tanker has no platforms, but lets players ride an Electro Shock Tank. It shoots electro shocks from its mouth, and has a quicker turn and charge than Blaze Wheelie. However, the lack of platforms can make it difficult to avoid players trying to steal the vehicle. If two opposing Electro Shock Tanks shoot at each other, the electro shocks will dissipate upon hitting each other.
