This is a great idea and should be done. - Add Women (no different from men) - Add kids (zombie kids included) Details: - Kids run faster, and can even run uphill faster instead of walking - They hold less inventory, and have worse accuracy during panic, after running, etc. - They are loud when they run - A group of bandit kids will be awesome! Aww how cute... until the 4 children overthrow you and loot you - Zombie kids should be one shot kills It adds to the realism. Oh, and no animal zombies as others suggested - it is a human virus.
