I had posted before, about this achievement not unlocking for me. At the time I was incredibly angry, and even now, I am a bit peeved about it.
Here is my situation folks.
Several months ago, I had started COOP with a friend of mine, and sometime later finished the campaign (Obviously). I had gone to my stats and awards and noticed that my "My Fellow Gears" achievement did not unlock. All acts and chapters were checked off, and the percent bar was at 100%, yet no achievement. So, after about a month or so of playing, I decided to get a group of people together to get the four person coop achievement, and succeeded in getting that. And yet again, still no "My Fellow Gears" achievement...I figured after I had completed it in four person, I would get the one for two, cause maybe I did miss something along the way. All four of us shot through the campaign in about 5 hours, so I know I did not miss anything.
My fellow gears lovers, I need your help!
If someone could please give me a suggestion as to what I could to to just unlock this, I would be grateful, and if it works, I will even dedicate a section of my signature to you (I am desperate, leave me alone).
People have told me to delete my data, and retrieve it, that sounds ok, except I do not know how to do it. And other people suggested "illegal" things I could do to get it....and I will not do that cause I want to avoid the EPIC banhammer.
A step by step way to fix this would be greatly appreciated.
