Heroes Underpowered?

[Rullys]

I've only played a few games so far, but from my experience I also feel as though the zombies have an advantage. They swarm far too fast! For example, I played a round of Save the Townsfolk with 4 friends the other day; the zombie player had 12 zombies on the board by the end of the second turn, while the heroes struggled to search in safe distance. Poor Nurse Becky player spent most of her turns trying to run away due to zombies spawning in the dang hospital. lol. But I think we'll balance it out with more experience. We've only had a few games.
