*Using various resources I have compiled a full list of all available missions and assignments that will help you toward this achievement. Each one can be clicked on to view a full walkthrough of that mission. Below are a few important notes before we begin:

1) Some of the missions won't become available until after you complete certain story related missions first.

2) Do as many of the side missions as possible! If you don't you may be cutting it very close by the end of the game or not get your achievement at all.

3) DLC does count toward this achievement.

*DOWNLOAD or VIEW a spreadsheet I created which you can use to keep track of the missions you have completed. It is fully interactive (hyperlinks included). This is my first spreadsheet so please be nice and give me constructive feedback. :)

*I will continue to edit and update this solution as new information becomes available. PLEASE CONTACT ME with comments and suggestions before downvoting.
