root@hyperion-db:~$ cat description.txt

A Hyperion repeater that trades some of the brand's usual pinpoint feel for a Vladof barrel's faster pace, larger magazine, and lighter recoil. It still rewards sustained fire as the aim tightens, but it plays more like an aggressive close- to mid-range machine pistol than a careful precision sidearm.

A related Hyperion pistol, the Expeditious, appears in Borderlands: The Pre-Sequel. It only appears at green rarity or higher and drops randomly from suitable loot sources.
