Fix requests:
One of the zombie spawns is missing light, so they are in pitch blackness.

People tend to grab magnums and go outside near the police car. Especially when only one zombie spawns, it is real hard to kill them. Perhaps make zombies spawn near the police car in the middle too.

Big house stairs is pretty easy to supercade, perhaps make it more challenging for survivors to create balance.
House when you take right at black car near (the house next to the television dawn of the dead house), should have less furniture perhaps, but zombies can still break into this one with many unlike the house supercade.
