I may add that when fixing the early "Deaddeard" error, but I wanted it so the cameras are very blury, so not much of them are seen.

As for the realistic approach, it kinda matches the quest-giving plants as well as the (of course) realistic feel that not all the plants and zombies want total domination for realism (and it's also to fuel the plot.)
