Borderlands 4 has added one of its biggest updates since launch, and it includes a number of quality-of-life fixes and upgrades, as well as a limited-time Halloween-themed event, Horrors of Kairos. As part of that, players will get a chance to earn two new Legendary weapons: the Legendary Order Grenade and Legendary Tediore Assault Riffle.

Horrors of Kairos is a free event that will run from October 23 to November 6, and it even transforms the weather during boss encounters into “a terror-inducing blood rain.” Players will get chances to earn the Legendary weapons by defeating the world bosses. Gearbox also revealed what each of the new weapons can do.
- “Murmur” Legendary Tediore Assault Rifle: Executes weakened enemies with guaranteed crits on targets under 35% health
- “Skully” Legendary Order Grenade: This deadly grenade fires projectiles as it seeks out the nearest target
Gearbox’s update notes included instructions for PC players with NVIDIA GeForce hardware to update their drivers to version 581.57, which was released on October 14. According to the studio, the update addressed “a number of GPU crashes.”
