As my MC's name was not Jack, I can confirm that Mary can fight as well. However it is unclear to me how to get weapons without cheating.In combat does anyone other than Jack get to deal any damage? I can take a small group of what I believe to be the most combat valued characters in the game (especially the two super soldiers) to the practice fight but when the zombies start coming the only thing the extra bodies can do is take damage while Jack spends time shooting twice and stabbing once to take out a zombie.
