Recently re-watched the first season of The Walking Dead. At the beginning of the apocalypse a lot of zombies can be seen eating corpses, which makes sense. I think this is a great feature that could be added to PZ (while obviously zombies would not eat other zombie corpses). While the zombies are doing this, they could be less aware of what is going on around them and less likely to notice the player. This would serve to lower the difficulty at the beginning of the game. After the first couple of days the frequency of this event should smoothly reduce to zero, as there are less survivors left. The animations for zombies consuming flesh are already in the game (as can be seen when the player is devoured). Due to this I think this feature could be added to the game easily.
I feel this addition would enhance the atmosphere of the game and make the world seem more real and frightening.
What do you think?
