Damn they suck at shooting. Look at that garbage grouping. That's like a 10 meter range too.

didnt UMP45 lampshade how sucky she was as a T-doll and this is prior to her character development

I had never thought about the effect of a suppressor on accuracy, but a quick googling told me one can't use it as an excuse.

There was a time UMP45 was far from being the A-Tier SMG that she is now.

Her accuracy is still awful, though. As were all the other SMGs.

Bonus: All SMG T-dolls never bother aiming at all.
