Basically it yep. You want free running where we are to get into the hospitals and police departments to get FAKs and Guns. Once you are you well armed you can go hunting, just take note of how many AP it took to get to the zed and then you can make sure you have enough to get back to Hutchinson.
Cheers, I'm going to go for the melee skill first then when I get to 100xp (on 81xp)as there are plenty round here with first aid kits to heal and I don't need ammo for guns (have axe plus axe efficiency).
