Hyperion repeater pistols are very accurate but they have the feature of "reverse recoil": the weapon has initial sway and only becomes accurate with sustained shooting. The listed accuracy on the weapon is what is achievable after the sustained fire increases their accuracy to maximum.
Due to its usage of the Vladof barrel, the Synergy has higher magazine size, higher rate of fire, and reduced recoil but decreased accuracy compared to other Hyperion pistols. It is a reliable pistol with medium to high-capacity magazine sizes and can quickly kill enemies at short to medium-range combat, especially in the hands of Zer0.
In addition to the Synergy, a variant of this weapon exists in Borderlands: The Pre-Sequel as the Expeditious, made by the "old" Hyperion.
The Synergy is obtained randomly from any suitable loot source.
