That's actually kind of interesting to think about.

I remember them saying they upped the spawn amount a ton and that the dev team had a bunch of fun with zombies everywhere, but the play testers at the time didn't seem to be too enthused. I think they posted a picture of a large group of the zombies too, I wouldn't mind hearing some more of these.

Answered directly or in a stream either would be awesome. The question I have is "Has anything been worked on and put in game that sounded like a cool idea and was later decided to be a horrible idea for gameplay and removed?" 

My question for the devs.
