Fortnite gets a new vehicle today, the Quadcrasher. Its a quad bike with a snowplough on the front. Radical. The new vehicle comes in the 6.10 patch, which also brings with it a refined Disco Domination mode and the new in-game tournaments. PS4 players who play on a 4K TV will now notice Fortnite now renders at 1440p rather than 1080p.
