Nah, they were only in Blackwater, and there were only so many of them. Probably about 30-40 when it started, but eventually we killed them all and they don't respawn or anything.

The townsfolk were perplexed by the zombies and didn't know what to do with them. They'd casually ride along on their or horses or stroll by the zombies and wouldn't attack them, regarding them as fellow citizens. Until a zombie started to try and harm them and then they'd start blasting, but by that point it was too late. The townsfolk did not turn into zombies following their demise, however.

But it's the closest thing you're going to get to Zombie Free Roam.
