Epic Games has detailed the latest patch for Fortnite on PS4, Xbox One, PC, Nintendo Switch, and iOS. Servers for the game were taken offline while update 5.20 was implemented and, among the various performance and gameplay tweaks, the update introduces new features to both the Battle Royale and Save the World modes.

One of the major additions in Battle Royale is the new Double Barrel Shotgun, which Epic describes in its Fortnite 5.20 patch notes as "devastating at close range." It continues: "the Double Barrel Shotgun packs a punch with each of its 2 shots." The update also throws a new limited time mode called Steady Storm into the mix: "This Storm waits for no player and there are no safe zones," Epic says. "Stay aware of the map and keep moving it to the center of the circle in the Steady Storm LTM."
