I have completed 25 survivors too. I tried to get a mix of normal folks, and odd balls that tend to be seen in the B zombie flicks. They were from Reaper, Hasselfree, Heresy, and Comfy Chair Games.
This one is a mix: Comfy Chair, Heresy, and Reaper.
I plan on either having the survivor player roll for or draw from a deck for his survivors. That way the survivors should get a different mix every time. I will do groups of two to three as follows.
Grandma and the kids
Church folk and an entertainer
I need to find a priest.
Regular folk 2
I am planning on having them armed pretty much as shown at the start of the game.
Hope you like.
