Key Items are special items that can be gotten by achieving certain milestones in the game, such as finishing all missions or Fulton extracting a certain number of things. These are usually required in order to develop the more elusive items, and they are also needed in order to get the Collector achievement/trophy . The following list will show what you need to do to get the Key Item, as well as what it unlocks. Remember that the item that unlocks has to be developed in order to become available.
