This was actually a hard decision for me to make.
On the one hand, I'm a naturally lazy, greedy, beer-swilling opportunist that would have lots of fun exploring all the freshly "liberated", no-longer-private property available. This puts me squarely in the "other survivor" category.
On the other hand, I love to play with large caliber automatic weapons, explosives, fire, and causing mayhem with various military tracked vehicles (or any vehicle, really). This draws me towards the "Zombie Hunter" camp.
In the end, I chose Zombie Hunter. I think you would have to be a good Hunter to enjoy all of the sudden opportunities available, AND keep from getting nibbled.
