San Antonio Church Zombie Assault

It's just another day at church, when all of a sudden, a horde of zombies tear through the parking lot and proceed to devour any breathing humans. Optimal setting: try 300 survivors, 20% armed, 35% accuracy, 50 zombies, Direction: Map Wide, Speed: Normal. Usually results in a (narrow) zombie victory. Mess around with these settings and see if there are any other combinations that work well. Enjoy.
