Thanks for the feedback! Currently all my posts need approval, so my interaction on my thread is a bit low because of that. I'm going to investigate that large zed spawn outside today. Thanks As for another floor, it seems very unlikely. Right now the 1st floor is a sandwich between ground and second floor where zeds can spawn. So it could unhinge gameplay. On top of that there is a serious performance penalty of having fully populated open floors like that. I agree it would be cool, but I'm going to focus on making things better in their current state.
