Are corpses created at any time other than by using the Raise Dead action? (For example, when investigators, zombies, or cultists die?)
Can action cards be used more than once per turn? For instance, could a Keeper use the Raise Dead card once to create a corpse, and then again to create a zombie from that corpse in the same turn? If a number of players were in adjacent spaces, could the keeper repeatedly use Take Sample to take a sample and then move onto the next player, allowing even the humble zombie to move up to five times in one turn?
Can creatures carry more than one sample?
Should every room with nothing of interest have a "Nothing of Interest" card on it?
Can (Or should) gameplay continue during another player's turn if that player is working on a puzzle?
What action is it to try to solve a puzzle? Is it the same kind of action as revealled the puzzle? (Move action to attempt to open a locked door, explore action to attempt an obstacle)
Is there any reason for a player to not die before the finale? It seems like the occasional death means you get to refresh your HP and sanity for free.
What useful tricks have players come up with to speed the game along?
