One of Fortnite Battle Royale’s most divisive and exciting weapons, the guided missile, is being put in the vault indefinitely, according to developer Epic Games.

A critical bug with the guided missile was introduced in patch v3.5, which contained a few nerfs to the weapon. The changes were intended to make it a little less powerful, but instead, broke the guided missile’s animation, forcing it to be temporarily disabled. After temporarily disabling the weapon, and plenty of player outcry, Epic Games announced that the guided missile will be taken out of the game.
