This part of the game is very difficult, I lost two characters including Jedi to manage to kill all the mercenary that were keeping the door of the tunnel. I just stayed with Atton, I had to retreat constantly to manage to kill those two towers that stay in the ramp. I stayed without grenade and without Packages of energy. Do anybody also had problems in this part to manage to kill the rebels?
Or it will be that I was mistaken ha hour to choosing better my attributes??
