Epic Games has released a new update for Fortnite on PS4, Xbox One, PC, Nintendo Switch, and iOS. Following the recent update 5.10, content update 5.10 marks the start of a new limited-time mode called Fly Explosives, which involves using jetpacks to cause mayhem. The update also pulls the Guided Missile weapon out of the Vault and puts it into play.

"The Guided Missile is back from the Vault and dropping into Battle Royale this update," the patch notes read. "In its time away, the Guided Missile has been tweaked and tuned down as it was too strong upon its initial release." The weapon now deals less damage, moves slower, and has a shorter fuse, among other tweaks. However, there are reports that might sometimes be invisible, which is a real problem.
