What if you could discover the US Open without ever leaving Fortnite? Ultimate Tennis Storm brings the energy of the US Open to Fortnite through a fast-paced multiplayer experience created by the USTA, Chartis and leading Fortnite creators Birdo and Dagwummy. Built into one of the game’s most popular user-created maps, Minigame Box PvP, the experience puts a tennis spin on the familiar Blade Ball-style gameplay. Instead of dodging a blade, players face a giant tennis ball that locks onto one player at a time. With only a split second to react, players swing their racquet to return the ball to another opponent. Every successful hit makes the ball faster. Miss your return and you’re out. Survive the rally and become the last player standing. The entire experience is transformed through the visual world of the US Open, from the giant tennis ball and racquet to the arena, effects, and player-facing interface. Launching alongside the 2026 US Open, Ultimate Tennis Storm is more than a momentary brand activation. It will remain playable through the 2027 US Open, giving players an ongoing way to discover the competition, energy, and spirit of tennis inside a world they already love. It’s the US Open, reimagined for a generation that doesn’t just watch culture—they play it.
