Storm is the title of a group of submachine guns in Borderlands 2 and Borderlands: The Pre-Sequel. They are manufactured exclusively by Hyperion and features the shock-only Maliwan barrel.

Usage & Description

The Storm is part of a sub-group of SMGs that only can spawn with a fixed-element Maliwan barrel. They feature the higher-than-usual elemental damage/second and element chance granted by the Maliwan barrel. These parameters achieve even higher values, if the SMG is equipped with a Maliwan grip.

Despite the low rarity designation of these weapons, their high elemental chance and status effect damage can make them excellent choices for combat until a more suitable (or less common, e.g. Legendary) weapon is obtained.


  • The Storm is only comes in green or higher rarity.
  • Other SMGs in this grouping manufactured by Hyperion include the Backburner (incendiary), Weisenheimer (corrosive), and Wellness (slag)/Cooler (cryo).
  • In addition to the Storm, a variant of this weapon exists in Borderlands: The Pre-Sequel as the Brainstorm, made by the "old" Hyperion.
  • The Storm is obtained randomly from any suitable loot source.
