Please see the link below, it is a walk thru for the mission. This mission cannot be skipped and there are missions that are need to be done prior to this one and there will be missions that follow it. There are links on this page that will get you to those missions' walk thrus. Skyfiredancer (talk) 07:13, September 19, 2015 (UTC)
