These are shot from the bottom part of the beam, so in situations, you are positioned above the enemy, they act as mortar shots. A single beam of the laser is shot by it, which comes with explosive burgers. Do not be deceived by the name as this weapon is incendiary. The Iceburger Legendary Shotgun is not similar to a Hyperion weapon by any means, despite its appearance.
It will increase the chances of finding the Iceburger Legendary Shotgun in Borderlands 3 Revenge of the Cartels. We recommend you to put your game in Mayhem 1-3. Go through the quest and the boss fight till the end to acquire the weapon.
To start this quest, you need to finish a task given to you by Maurice and then you receive access to Villa Ultraviolet. You can find it in the boss fight at the end of the Revenge of the Cartels: Ultraviolet Nights, from mini-bosses that are paired up with Joey UltraViolet.
It is not possible to directly farm this legendary weapon as it does not have a direct drop.
