After Shepard surrendered to the Alliance before the start of Mass Effect 3, Jack, oddly enough (given her criminal past), was recruited into the Grissom Academy's biotic training project, Ascension, as a teacher. In addition, at the request of the Directorate of the Academy, she now had to change her image and monitor her speech. Without even realizing how she agreed to this, Jack nevertheless quickly found a common language with the students. This variant of Jack is not found in the game, but, apparently, this is one of the interpretations of Jack at some of the important events of the academy.
The skin is made qualitatively and works in SAMP without any problems.
Have a nice game!
