I would! That's what I enjoy about this idea... Our job is to create a zombie horde to destroy humanity! I also had imagined that the zombies wouldn't attack us, but it's your game, and I see your positioning. I figured difficulty would be increased with more powerful civilians... we'd be building a zombie army, after all, so they'd get increasingly concerned.

Ah... OK, sorry for the mis-understanding. Very well, then... Zobies WILL attack the NPC's if they are attracted to them by sound or sight.
