1. If you pop open a building and a necro spawns inside of it, does he place his spawn token in the room he appears in?
2. Just wanted to verify that with shove, I can push an arbitrary amount of zombies, and of any type; so even crows or abominations would be shoved. The rules seem clear, but that skill just seems ridiculously powerful so I wanted to double check.
You are correct here.
3. Scenario 1's objectives are to kill an abomination and a necromancer; and to hit all the objective tokens. If we've already killed abomincations and necromancers, do we win the moment we activate the final objective? I assume so. Just was weird in the game I played tonight because the necromancer's hidden lab happened to be the last one we searched (necro was spawned via the deck).
That's the case, yes. You just found the Necro and his experiment before finding the lab.
4. Scenario 1's map features a gigantic building with 9 rooms. Just wanted to verify that every room in this building spawns zombies the first time it's opened.
That is true, regardless of which of the 5 doors you open into that building (including the vault door).
