** This is the one where you have to kill all four zombie types in one Dead Eye meter.
I am having quite a time with this one. I have heard two good areas are El Presidio and then Jorge's Gap where there are dozens walking around.
I never see a bolter in El Presidio and never see a Retcher in Jorge's Gap.
I was thinking one strategy might be to go to Jorge's Gap, go into Dead Eye and use the Explosibe Rifle over and over until you got the right combination of kills -- but I am just not seeing any of those green Retchers.
Any help is appreciated!
