We played this scenario last night and it was a ton of fun! We had a question though:
A fire was blazing in the center square, and we had a hero death, which meant the new hero was forced to spawn in the center (that's the scenario rule). Do we roll for fire damage?
You roll for fire damage whenever one of these things happens:
-a fire starts in a model's space
-a model enters a space with a fire
-a model ends its move in a space with a fire
We debated this and decided that #2 applied, but agreed in the future we should house rule that since heroes have no choice, they shouldn't have to roll for fire in this situation.
-we said if fire was on a spawning pit, we would want zombies to roll for fire damage when spawned or placed there (e.g. via a card)
-escape in the truck scenario allows cheesy hero spawn for insta-win (which we also now house rule against)
Based on that, it seemed most fair for this play to roll for the damage.
I suggest FAQ/errata to clear this up. Perhaps give heroes option to spawn In a random building, but not in the hero start area.
