In Mario Kart World, the Hammer item lets drivers throw hammers at rivals.
Using the Hammer gives a racer a way to attack opponents ahead on the track. The thrown hammers can interfere with rivals directly and can also remain on the course briefly, creating an additional obstacle for approaching drivers.
The Hammer is easy to mix up with the Super Horn, but the two items work differently. The Super Horn emits a short-range blast around the user, while the Hammer is thrown outward. A Bob-omb is also an explosive projectile, but it does not create the distinctive hammer obstacles associated with this item.
Mario Kart World adds several unusual items to the series' familiar selection. Alongside the Hammer are the Ice Flower, Coin Shell, Mega Mushroom and Kamek. These items help the game's long connected routes feel different from the traditional three-lap circuits in earlier entries.
