7D2D specifically. I want the overall gameplay to remain the same, but to have single player running as a human hunter.
Some additional thoughts, the hunter could be afflicted by the radiation. As such they are a tad faster and stronger than the survivors, and they do not suffer from inventory encumbrance (all slots unlocked). They can also harvest meat, bone, and fat from a slain survivor as they are a bit cannibalistic.
But due to this, they are ostracized from humanity, meaning they can never enter into a trader location, nor can they kill a survivor that is in the confines of a trader.
