Yes, he does. The Unforgiven becomes spectacular with it.
On topic- sorry, I just got mine. I've been farming for a Two Fer Unforgiven for days, and finally got one. :3
Lol. It becomes worse.
Snagged a couple thanks to Redrum, and Im really not seeing where youre getting that they become worse.
Both guns have an abysmal fire rate, so doubling the projectiles per trigger pull does not make them worse. There's the off time or two that one of the rounds veers off of the other, but for the most part, both of the rounds are hitting and Im actually having fun with a gun that I had previously found to be worthless.
I have Dastardly versions of both Rex and Unforgiven, but they dont match what the Twofers can do for me.
