Old Hyperion is called Expeditious. New Hyperion (and, subsequently, the ones in BL2) are called Synergy.
That one is like old though , but same name. 1. It does not zero in, it gets more accurate but not pinpoint 2. Much slower fire rate 3. Its got the old color scheme.
I thought that was the pre-fix and for Maliwan, iirc. I’m pretty sure I have an Expeditious Thunderball Fists. I could be mis-remembering here.
I think your right about it being a prefix for the Tball Fist. I’m about 87% sure I had one at some point.
Expeditious does serve in both capacities. It’s the fire rate accessory for Maliwan pistols, as well as the name of the line of Old Hyperion pistols with the Vladof barrel.
Not sure I’ve ever run across that.
