Old-style Hyperion's SMGs have higher damage output at the cost of significantly lower accuracy and fire rate than their modern analogs. They also have a limited version of Hyperion's "reverse recoil" when aimed down the sights only.
This SMG does not have any stats that stand out amongst the other old-style Hyperion SMG weapons. The only aspect improved in it is a reduced recoil thanks to the Dahl barrel that it comes with.
In addition to the Confidence, a variant of this weapon exists as the Presence, made by the "new" Hyperion.
The Confidence only comes in green or higher rarity.
The Confidence is obtained randomly from any suitable loot source.
