In order to make time for writing I must give up working or gaming...
Q1. When a lockdown event card is in play what should I do:
1) should I turn all the doors to locked face and should I unlock a door in the next turn
2) All the open doors stay's open and the next turn I can pass through them
I think the doors flip to the red (locked) side immediately. They stay that way until the next Event Card is drawn. The flip back to green (open) just before the next Event Card is read out.
Q2. Does noise passing through walls?
Yes, it seems so.
