Apparently the "higher ups" decided to leave this planet to the Separatists. My crew and I fought our way out of there as quick as we could. We got to the evac point, and teamed up with the Galactic Marines, just as our shuttle off this rock was arriving.
This one, while not as cool as Mission 4.2, is still nice in my mind. I wasn't quite sure what to do for this one. I did come up with this idea though.
