I have been trying to get the achievement: "Agent of the Unseen". I only have 1 update left to get it and it's the questline called "Tracking a traitor". I assume this is a defiant only achievement because it follows the story line of Kira and Uriel. I have searched online and have tracked down one thing, that I should have a quest item called Kira's signal. I checked my quest items and I don't have this.
Can anyone out there point me in the right direction? Or at least tell me how to re-start this quest so I can get the signal again.
Thank you for any replies
