Borderlands is officially ten years old this month, so Gearbox is throwing a party to celebrate. Instead of cake, though, you'll get a month of special loot events in Borderlands 3. It's sort of like busting open a birthday pinata, if the pinata were full of guns.

Every week for five weeks, Borderlands 3 will offer a special theme. The first week, which is already underway, is called "Boss Week." During Boss Week, several bosses will have increased odds of dropping a unique legendary. You can check out the bosses and their loot rewards below. Boss Week will last until October 8. It will be followed by Rare Spawn Hunt, Show Me The Eridium, Mayhem on Twitch, and Spooky Surprise events.

Details of the other four events are forthcoming, though the Spooky Surprise in late October would line up with what we heard about the Bloody Harvest free DLC. But, Gearbox may have other Halloween haunts planned as well.

Meanwhile, Gearbox is also issuing a patch and hot fix that addresses some balance and performance issues. For more on Borderlands, check out some of the best anointed weapons and how to grab some great loot with Shift Codes.
