In Hard Duty, you play as Henry Jefferson. Barely acquiring his PhD in theoretical physics, distant and silent, after the mysterious disappearance of his wife, nothing appeared to look or sound normal. Henry joins the Black Mesa Facility and is bumped to an important position only a few days after. Soon, Henry will realize things are not what it seems like.
