I don't think you need to worry about locating the hunter. This is a coliseum-like battle. Everyone is on the ground level, so that hunter is at the mercy of the rats and hawks. That's why I didn't pick him. fukk is a rifle gonna do when a grizzly bear and a gorilla is coming at you?
Both of those alone are gonna take multiple rounds and if they're coming at you from multiple angles, that lil gun ain't gonna do shyt.
