It’s not even that rare, you won’t find them as much as Volcanos or Equalisers, but in comparison to Atlas/Hyperion legendaries it’s super common.
Getting a ZPR with big mag, mat3 and a decent barrel is the real challange.
Also: when I say “speed glitch” I don’t mean the one where you activate Beserk and instantly hit the Inventory button, I’m talking the REAL speed glitch:
The one where you activate Beserk and instantly get into a car, then get out.
I’m not sure if the type of car effects it, but if I’m in Knoxx I use a racer anyway. But a vanilla Runner is just as stupid fast.
It’s pretty game breaking though, if you sprint it’s almost Phasewalk speed. I only use it to cheese Craw (you can backpedal his spit) or just having fun. If I’m playing properly I don’t use it, since it feels so weird.
