Just in time for spooky season, Borderlands 4's first free, limited-time Seasonal Mini-Event, Horrors of Kairos, will scare all players senseless from October 23 to November 6. During the event, world boss encounters change the weather to a terror-inducing blood rain, with new Legendary loot you have a chance to get from world boss kill rewards:
- "Murmur" Legendary Tediore Assault Rifle: Executes weakened enemies with guaranteed crits on targets under 35% health
- "Skully" Legendary Order Grenade: This death-dealing grenade fires out projectiles as it seeks out the nearest target
In addition, we'll be serving up some SHiFT code treats during the event: a "Gourd Your Loins" Vault Hunter (pumpkin) Head usable by Vex, Rafa, Amon, and Harlowe, and a "Hex Appeal" Weapon Skin that can be equipped to any weapon.
