From the campaign:
An unthinkable crisis has struck the Echo Ridge Mall. A mysterious outbreak has claimed the lives of nearly everyone there... what's worse is they are crawling the stores and commons as Zombies hungry for flesh. Only a few Survivors remain. Are you among the Survivors? Or are you one of the ravenous Zombies? The choice is yours in Tiny Epic Zombies!
I'd say the campaign's doing well, being more than 21x funded. So you can jump in and see what all sorts of stretch goals have been broken and will hopefully continue to be broken for the next 20 days.
