Hello all, brand new to Zombicide here. Gotta say I am loving this game. I do have a quick question though about doors. The game states that if there is no path the zombies will move thru doors as if they were open, but locked doors still stop them. I am a bit confused by this as all the doors are in fact locked doors. Also the lock it down ability allows you to simply close it again and not actually lock it. I am also noticing that with other expansions the doors are simply labeled as "door" and not as "locked door". Was this an oversight in the original book or am I missing something important? This question came up with my group when I purchased Black Plague and it's expansion. The first mission has a spawn point behind a couple doors. So I suppose in short, how do we determine whether a door is locked or simply closed and do closed doors still need to be battered/hacked open?
