Oh nice job there
Well now it most likely is xD
this is probably fake, becuase the description supposed to say how to get the achivement, like every other achivement, but in this one, it just says : “Difficult to extract with extrusion”.
and in the last archives achivement, it says : Complete Retribution with each of the 4 heroes.
Does it match her Noire Skin maybe?
