In papa Jeff’s interview with IGN, he told them that the Overwatch team does not want to release any more male heroes. So Hammond, Maximillian, etc are WRONG
Edit: Unless Hammond suddenly becomes a female name or Hammond is secretly a trans chimpanzee, he will not be added.
Just because they don’t want to doesn’t mean they won’t. They’ll release heroes depending on what the game needs at the time we needed more supports so they gave us Ana, Moira, and Bridgitte. See what I mean?
