The All Terrain Kart, or ATK, is one of the more exciting details about the just-released season five of Fortnite. And it looks like the new vehicle is going to reward teamwork.

“The All Terrain Kart has room for your entire squad,” the Fortnite team wrote in the game’s official patch notes. You’ll get a speed boost from drifting, and players can use the roof of the vehicle as a bounce pad. Players will have to time their jumps to get over bigger obstacles, however.
