The figure in the picture is the three-sense image of DNF female machine. The prefix after the three senses is the same as the male gun profession. At the same time, it exposes the three senses of the four occupations of female guns, and the appearance has also changed greatly intuitively. I believe that the three-sense vertical drawing of the female machine will be loved by the majority of male players, especially the one who pushes glasses.
