About the HRA mission
Within the story, Jesse will encounter people that were not taken over by the Hiss.
These people are all wearing HRA's, a torso belt that acts like a shield towards the Hiss.
Only Jesse and the Janitor don't need HRAs.
In the HRA mission, the machine in the HRA lab has to be configured so more HRAs can be produced so the people still stuck in the shelters could come out and help contain the Hiss.
